Living With a Low-Yield Well

Slow wells and running out of water are no jokeSlow, low-yield water wells are no joke, as I learned when I nearly ran out of water one summer. Yikes! Running out of water is seriously Not Fun.

How did we fix our problem? More importantly, how can you fix your problem?

Can you need a new well? Maybe not! With the right setup, you can have all the water you need with a very slow well. We do fine with a well that gives only a quart per minute.

What is a Low-Yield Well?

A low-yield well (also called a “slow well”) is a water well that has delivers water more slowly than you need. Since a well is basically a hole in the ground that water seeps into, if you pump the water out of it faster than it’s flowing in, eventually the water coming out of the pump falls to a trickle or stops altogether.

Symptoms of a Low-Yield Well

If you have a low-yield well, you’ll have at least one of these problems:

  • Running out of water. Everything is fine for a while: you have plenty of water and plenty of pressure, but after a while the flow and pressure fall dramatically, possibly to zero. If you turn off the taps and wait, everything recovers after a while.
  • Low water pressure, low water flow. For example, shower dribbles instead of spray.
  • Dead pumps. Your water pumps don’t last long before burning out.

When I first moved to my farm in Oregon, we could water the lawn for about an hour, and then our water pressure would fall almost to zero and we’d get only a trickle of water. If we turned off the hose, our water pressure would recover in about twenty minutes, but would quickly fall again if we turned the hose back on. We’d have to wait hours to get another chance at watering the lawn.

Depending on your particular well, you might run out of pressure even faster: partway through a shower, for instance.

Also, the problem may be seasonal, with plenty of water during months where the water table is high, and little when the water table is low. Your well may still give water during the driest months, but not enough—unless you take the steps I describe later on.

It’s All About Your Local Geology

If you’re in an area where it’s easy to drill a well that gives you all the water you need, you’re lucky! Here in the Pacific Coast Range, we suffer from the irony that we get a lot of rain, but the aquifers yield up water grudgingly. Good wells are few and far between in my area, so we learn how to get the most out of poor ones.

Anatomy of a Basic Well System

A home water system is a pretty simple proposition:

  • Drill a hole in the ground until you hit an aquifer and water pours into the well.
  • Drop a pump down the well and connect it to your household pipes.
  • To keep the pump from running 24/7, add a pressure switch to turn the pump off when no water is being used.
  • Add a pressure tank to hold enough water at pressure so the pump doesn’t have to turn on every time you open a faucet.

Typical domestic water well


If water pours into the well faster than you pump it out, you’ll always have plenty of water and plenty of pressure. You don’t have a low-yielding well.

How Much Water is Enough Water?

When I bought my farm, the rule of thumb lenders preferred was that the water system should be able to produce 600 gallons over the course of two hours, or five gallons per minute. It can be difficult to finance a home purchase if you can’t pass this test.

What if your aquifer is stingy, and simply can’t deliver this much water?

My well produces only about a quart per minute, or 360 gallons per day. How can I pass a 600-gallon flow test, let alone have enough water during peak usage periods during the day?

Water storage, that’s how. Clearly, through the miracle of a full-to-the-brim 600-gallon storage tank, anyone can pass a 600-gallon flow test. You could have a dry well and still pass, if you have a water holding tank and pay someone to truck in the water to fill it with.

So the test the lenders use doesn’t actually measure the water well yield. Which is nice, but what about after you move in? If your lack of water is driving you nuts, it’s time to do something about it.

The Slow Flow Paradox

One thing about my quart-per-minute well is that a quart per minute is somewhere between a trickle and a dribble. It takes more than six minutes to cycle a 1.6 gallon/minute toilet, and taking a shower is almost impossible.

On the other hand, there are 1,440 minutes in a day, and in that time my quart-a-minute well produces 360 gallons. This is plenty of water for a family of four. So if I capture all the water my well is capable of yielding, we have plenty of water.

How do we capture 360 gallons per day, so we can use it whenever we want? We need to acquire some storage. A cistern, a reservoir, a storage tank, a holding tank—call it what you will.

Why? Because, unless you have an artesian well that has water flowing right out of the top, without a pump, every well fills itself up to a certain level (the static water level), and then stops. No more water flows in. If you pump some water out, more flows in. But once it’s filled to the static water level, it stops.

I need to be able to harvest my well’s pathetic dribble of water. I can’t afford to have it sit around at the static water level most of the time, not producing water for me. So we need to do one of two things:

  1. Drill the well with a large diameter that there’s plenty of water storage inside the well itself.
  2. Add a storage tank for the well water, and run the pump often enough that the water in the well doesn’t reach the static level.

Storing water in the well itself

Storing water inside the well shaft works just fine with a simple well setup: well, pump, pressure switch, pressure tank. The pressure tank really only stores a few gallons, so that’s no help. But you can store water in the well itself. That’s what a well is: a hole in the ground with water in it. You can create storage by making the well wider, or deeper, or both.

My older well has the aquifer at 85 feet, but the well is 145 feet deep. That extra depth acts as a reservoir that holds about 150 gallons. Using extra depth for storage is a side effect of the luck-of-the-draw nature of the well-drilling process. You’re never sure what you’re doing to get, and if you hit a shallow aquifer with a disappointing flow rate, you tend to keep going, hoping to find more water further down. If you don’t, at least you’ve created some water storage.

So let’s do the math. If my well yields a quarter-gallon per minute, and the well has 150 gallons of water capacity, how long until it’s full again? Ten hours (600 minutes).

How long until I have water pressure again? Depending on how things are set up, you might have a dribble of water continuously, but the water pressure won’t rise to normal levels until you’ve been using no water at all for a while. For example, a low-flow toilet uses 1.6 gallons of water, and if the toilet is flushed after the pressure has fallen to zero, the household pressure won’t rise until sometime after it fills. On a well like mine, pressure doesn’t come back for tens of minutes.

Using a Storage Tankplastic_water_tanks

Our original well, with its 150 gallons of in-well storage, worked okay for us for a couple of years, once we gave up on the idea of watering the lawn during the summer. Later, as we got into the broiler butchering business, we started running out of water at inconvenient times. So we added a 1500-gallon holding tank. We got one that’s basically a big black plastic tank about eight feet in diameter and six feet tall. They’re light. The guy who delivered it just rolled it off his trailer by hand, rolled it across the grass to where we wanted it, and got a couple of us to give him a hand in tipping it upright. Easy.

In my mild climate, you can just set one up outdoors and forget about it. In a climate that’s hotter or colder, you’d either build a shed around it or get a concrete tank instead and install it underground.

With a storage tank, you have a two-pump system. One pumps water from the well into the storage tank. The other pumps water from the storage tank into the house. The well pump is controlled by a float switch in the storage tank. The household pump has a pressure tank and pressure switch, just like the basic water well setup.

When we installed the tank, it went from being empty to having 400 gallons in it overnight, which was wonderful. In a few days, the tank was full, and it stayed full from then on, unless we did something that used a great deal of water (usually leaving a faucet on by accident).


Protecting the Pump and Well

“Is my well dry, or is my pump bad?” Preventing the pump from going bad is the simpler part of that question. Electric pumps rely on the water passing through them for cooling. The pump in a slow well tends to have long periods when it’s running, but not much water is passing through it, so it overheats. This also tends to use up electricity to little purpose. What to do?

There are several solutions for this:

  • Use a float switch or water level sensor down the well that turns off the pump when the water level gets low. End of problem, but it involved dropping an extra cable down your well. I’ve never tried this.
  • Install a Pumptec pump-protection box. This is what everyone actually uses. The Pumptec basically does what a down-the-well float switch would do, without putting anything down your well. It’s an electrical box installed in series with the power to the pump. It monitors the current load of the pump, and if it sees it running with very little load, it infers it’s running dry and shuts it off for a programmable interval. More on this later.
  • Install a cycle timer that only allows the pump to run a set number of minutes every hour or half-hour. If you set this right, the pump will never quite have enough time to pump the well dry. I used to do this, but it confused the electrician and he took it out, and I haven’t put it back. More on this method later.
  • Use a smaller pump that can’t over-pump your well. The 3/4 horsepower submersible pumps I have in my wells pump water 20 times faster than my wells can deliver it. A tinier pump would be better-matched to the task.
  • Put a valve inline with the pump and close it most of the way so the output of the pump is about the same as the production rate of the well. Seems sorta wasteful…

Protecting Your Pump with a Pumptec

protect your slow well with a pumptecIf you have a low-yield well, you want a Pumptec unit to protect your pump. This is a device that sits up in your pumphouse and monitors the load on the pump. If the well runs out of water, the load on the pump goes to zero, and it can burn out. The Pumptec box turns off the pump as soon as it detects the no-load condition, and won’t let it come back on for a while, at which point there will be more water. Mine is set for a two-hour delay, but you’d set it for a shorter delay if your well isn’t as minimal as mine.

Protecting Your Well With a Cycle Timercycle timer for slow wells

But it’s better if you don’t pump the well dry: the well lasts longer if it’s mostly full all the time. If you have one gallon a minute (I wish!), and a pump that delivers ten gallons a minute, you’d never pump the well dry if the pump was allowed to remain on for only six minutes out of every hour. I’ve used a timer with a 30-minute cycle, which would be set for an on-time of three minutes out of every 30 in this example. When you have an external storage tank, you don’t much care exactly when the pump is on.

I don’t know how much this actually helps, and neither of my wells have a cycle timer on them anymore, though both have Pumptec units.

All-in-One Solutions

I’m aware of two companies that create packaged solutions to take care of the entire problem, using fancier controllers than mechanical cycle timers or even Pumptecs. These are:

  • Well Manager, which emphasizes its compact rectangular water storage tanks that you can sneak into your basement, behind the stairs, etc., in addition to its controllers.
  • Well Booster, which controls up to five wells with a single controller.

Redeveloping Your Well

With a storage tank, a Pumptec unit, and a cycle timer, all was well for several years. Then, one day, I discovered one day that the tank was nearly empty. A day later, it had gained only 50 gallons from the day before. Hey! It used to gain 400 gallons overnight! Our well had clearly become less productive over the years.

redeveloping a slow water well with compressed airSo I went down to Mainline Pump in Philomath and got on the calendar to have them show up, along with Corvallis Drilling, to “blow out the well.” This is also called well redevelopment or well rehabilitation. Wells can get themselves crudded up over time with silt and harmless slime bacteria, and this can often be reversed by removing the crud by one means or another. I knew I had a slime bacteria problem. This is not a subtle problem, since the hydrogen sulfide smell in the water and the slime on the water filters and in the toilet tank are a giveaway.

When the day arrived, Mainline pulled the pump, and we removed about a bucketful of slime was clinging to the pump and drop pipe even before the main event started, and plenty more came out after Corvallis Drilling dropped their hose down the well and blasted it out with a combination of compressed air and water (airlift pumping). It was an impressive spectacle, but unfortunately the yield we measured at the end of the operation was under a quart a minute. Sigh. There are no guarantees in the well business. You give it your best shot, and you get what you get.

Drilling a New Well

corvallis drilling rotary well drilling rigSo we asked Corvallis Drilling to drill us a new well, not far from the old one. Heck, the rig was already there and everything! The old well was blown out on Friday, and they drilled us a new well on Monday. This was done with a truck-mounted air-rotary drilling rig, which is pretty much the standard these days. The well is six inches in diameter, and after the first few feet, the whole operation was through rock. Most of it was crumbly, easily drilled sedimentary rock, with occasional barriers of harder sandstone. Usually the water is found above these harder layers. The drill turns very slowly. Water is injected as a lubricant, and compressed air blows out the chips as the drilling continues.

I kept sneaking out to watch the drilling in spite of a deadline that was supposed to be keeping me in my office. (But I met the deadline, too.)

In our neck of the woods, there’s no real reason to drill a new well very far from the old one, since everyone’s experience is that nearby wells don’t interfere with each other, and a well thirty feet away from an existing one may find water at depths and quantities totally unlike the first one.

After looking at the well logs of all the wells drilled in my neighborhood in the last forty years, it seemed like we’d probably find all the water there was within 100 feet of the surface, though there was an off-chance of finding more very deep—300 feet or more. Sometimes that deep water is salty, sometimes it’s fine.

We hit water at 55 feet (the old well, thirty feet away, had hit water at 85 feet), but the amount was disappointing, around a quart a minute. I wanted to quit at 100 feet, but the driller offered to go down to 130 feet, and if he didn’t find any more water, I wouldn’t pay for the last 30 feet (except for the 30 extra feet of PVC well liner). So we did, but no dice.

Mainline Pump showed up to put the old pump down the new well, and … it was a disappointment, about the same yield as the old well. Enough to scrape by on if we were careful. Sigh.

I was reluctant drill yet another well (among other things, the State of Oregon charges fees that cost nearly $600 per well, let alone the drilling costs), so we moved on to Plan C, which was to put both wells into operation. Mainline Pump came out yet again and put a new pump down the old well.

Success! In the 24 hours after both wells were in operation, the storage tank gained 500 gallons, and has basically been full ever since.

Hanging Onto the Last Few Gallons

If float_switch_water_storage_tanksomeone leaves a faucet open, all your hard-won storage can vanish in a few hours. But you can create a reserve supply easily. Here’s how:

  • Put a float valve near the bottom of your storage tank and put it in series with your household pump. Use the normally-closed version of a float switch, so when the water falls to, say, one-quarter of a tank, the switch opens and your household pump stops running. This will prevent your household pump from burning out and will also protect your last few (hundred) gallons.
  • twist_timer_for_wellsWire in a twist timer in parallel with the float switch. That way, you can go out to the pump house and bring the pump back to life for a limited time. Twist timers are available with durations up to six hours. (You could just install an override switch, but if you’re like me, you’ll forget to put it back in the “Normal” position after the water emergency has passed.)

Making Your Well Last: Disinfection

One thing that well owners are supposed to do is to disinfect the well to control bacteria, including bacteria that can cause disease and slime bacteria that can plug up the well. I’ve been doing this all along, but obviously not very effectively!

Shock Chlorination

use bleach to shock chlorinate wellsThe usual technique is shock chloriniation, where you dilute a appropriate amount of bleach (in my case, 3 quarts for each of my wells) in five gallons of water and pour it down the well, then circulate the water by running the pump and pouring the output back down the well. Then you let it sit as long as you can (at least eight hours, though 48 hours or longer is even better), and finally pump it out onto the grass, since you don’t want all that chlorine in your septic system. This beats back the bacteria. More on shock chlorination.

I recently learned a better system that’s available to those of us with storage tanks, which is to fill the well up to the top with water from the storage tank after adding the chlorine. This water will run backwards, into the aquifer, and kill off bacteria that are relatively far from the bore of the well. Then recirculate and wait as before.

Hydrogen Peroxide

hydrogen peroxide to disinfect and deodorize well waterAnother technique I learned about more recently is the use of ordinary 3% hydrogen peroxide instead of chlorine. This hasn’t been adequately researched, so it counts as a backwoods rule-of-thumb technique rather than something that will put a smile on the face of an inspector. The way it was described to me was, “Pour a couple of pints down the well and a couple of pints into the storage tank, and forget about them.”

The theory is that hydrogen peroxide is safe at those levels and doesn’t put any annoying tastes or smells into the water, so you don’t have to dump the water in the pump and the storage tank. Simple.

I wrote two different state agencies in Oregon to get their opinion about this, and basically they feel it doesn’t have enough research backing to be considered reliable, though they didn’t see anything scary about it.

One thing is certain: hydrogen peroxide works great for getting rid of sulfur smells in water, and it’s used routinely for this. When I got a new water heater, I was plagued by rotten-egg small in the hot water, and it went away instantly when I put some hydrogen peroxide in the system.

Because sulfur smell has been a problem for me, I expect that I’ll shock-chlorinate my well every year to stay within the usual parameters (after all, I have a state-licensed chicken and egg operation here), and use the peroxide in between. While I hope that its effects are more far-reaching than this, I won’t count on it.

Water Conservation

I saved this until last because people who don’t have enough water are already conserving what little they have. Just a few tips:

  • It’s ridiculous, unbelievable how much of a difference a low-flow toilet makes. In a family of four, I wouldn’t be surprised if our old adorable antique toilet used 100 gallons per day! Compared to this, all other conservation methods combined were a bit of an anticlimax.
  • If you used to have low water pressure, you probably couldn’t get low-flow shower heads and faucets to work right. I sure couldn’t! But after I added a storage tank and had separate well pumps and household pumps, I had tons of pressure, and swapping out my fixtures worked great.
  • If you insist on sending precious well water through lawn sprinklers, always use one of those timers that shut off the water after the specified time.

  1. I had no idea that there were so many steps that you could take if your well wasn’t producing a lot of water. I always figured the easiest solution would just be to drill another well, so I’m glad you had that listed. All of your other suggestions caught me a little off guard though. I have a well that hasn’t been giving me quite as much as I’d like, so I’ll have to try some of these things out. Thanks for sharing!

    1. Can you please tell me the name of the pump cycle timer you referenced in your post? We have a well that produces about 2 gallons a minute, for about 15 minutes, and then the pump saver kicks the pump off. I’ve only been able to find timers with a 15 minute minimum run time. I really need to find one that can handle a 3 horsepower pump that can be controlled down to 5-6 minutes, and also be set to run hourly.

      1. Dante,

        I’ve been using the Paragon JW Series 30-minute cycle timer. I suspect this is no longer manufactured. recommends the Intermatic CT2000 timer, which you can set for a cycle time between 30 seconds and 4 hours, with an on-time per cycle selectable between something like 3% and 97% of the on time. So setting it for a few minutes per hour is well within its range.

        This is a 1 HP switch, so you’d want to find a beefier version or use it to control a relay that’s rated above 3 HP.


  2. Thanks for the great information. Now that the hot & dry weather is back in beautiful Boerne, TX we will be referring to this information when our customers water pump and water well systems show signs of running out of water or other related water system repair & service.

  3. i could not have asked for a more excellent description of your situation which, in many ways, mimics my own. we are sustainability experts who apply our knowledge to our own home/family of four. as such, our 200 foot (arizona), < quart/min, 700 gallon storage tank, pump-tec, pressurized system is similar to your own in many ways. when it rains it pours around here so we harvest rain. however, in our heat, the veg garden, chickens etc. are thirsty so we do water from the well. our usage in the home is likely 30 g / day on a bad day (e.g., niagra stealth toilets at 0.8 gpf, water saving adapters and appliances, frugal usage etc.) so our low-producing well with the pump-saving pump-tec works just fine. but we travel and our house sitters routinely drain the well and storage tank and create costly risks for our system (e.g., pump between tank and house running dry) so we are moving on your suggestion about a lower-level float switch to stop the loss when a hose is left running. Your timer switch is an ingenious idea… i will steal that one outright.

    this has been the most educational post i have yet found on this topic.

    so, i have three remaining questions:
    – 1. will pouring the bleach shock solution directly into the metal storage tank be good enough? or must i really send it down the well (I don't yet know how to do that).

    – 2. our 1970's metal water holding tank seems fine on the outside but inside it is quite corroded. is this a health problem or are we just boosting our iron? tests of water from the house faucet come back sublime.

    – 3. if we were to replace the water holding tank from metal to plastic… or some other material… what material would you recommend (assuming you've looked into this) in terms of water quality for health considerations?

    again, thanks so very much. a GREAT post… best i have ever seen… by far. (and I've looked around.)

    1. Peter, thanks for the kind words!

      Let’s see if I can answer your questions:

      1. Shock chlorinating the well is done partly to keep the aquifer open by discouraging slime bacteria in the well bore. Only stuff you actually pour down the well helps at this task. If you do a Web search on shock chlorinating domestic water wells, you’ll find plenty of information. Disinfecting the storage tank is also a good idea, and many pages on shock chlorination cover both.

      2. I don’t know much, maybe not anything, about the implications of corrosion in metal water tanks. Like everyone else, I’ve had to replace rusted-out water heaters, but I never gave much thought to any aspect other than the water and steam shooting out the rust holes.

      3. For my reservoir, I used a standard black plastic 1,500-gallon tank, the same kind everyone uses. It didn’t occur to me at the time to research the differential health risks of different materials. (Presumably the options are plastic, concrete, steel, maybe fiberglass, and perhaps wood. For added confusion, you could take any of these and line it with something else.) As far as I know, the dominant issues come from geometry: the ease with which the tank keeps the wrong things from getting in (insects, bird droppings, etc.), and the ease of access for inspection and (god forbid) cleaning.

      1. We started using a white storage tank , within a week we had a real bad green algae slime problem, I added bleach which seemed to “kill” the green stuff, now we have some kind of white gunk growing. Could we paint the tank?
        Will bleach or peroxide down the well take care of this problem at the source?

        1. I’ve only ever used a black storage tank, so I don’t have any special insight. I’d assume that painting it on the outside with something opaque will make your tank behave like mine, or better, since my black tank allows the water to get warmer than I’d like in the summer.

          When I put peroxide down the well, there’s no sign of it by the time the water gets pumped into the tank, and I assume that all of it has reacted with the stuff in the well. So I also put peroxide in the tank. Bleach leaves a horrible taste no matter what I do, so when I put it down the well, I pump out the well onto the grass, wait several hours, and pump it out again before letting it pump water into the tank. For the same reason, I try not to put bleach into the tank.


  4. I like that you described what a low-yield well was. If I had a slow well I would want to know what the professional was talking about when they described what was happening.

  5. First class practical information from a expert with first hand experience. . Only article you need to read if you have problems with a tube well. I gained a lot of information in a few minutes reading this article…..and I have wasted many hours looking through the internet. Many thanks.

  6. Dan from Well Manager, LLC. Robert your personal experience speaks for itself. Good information and accurate. Well Manager is the only patented well collection system on the market today. Our standard Well Manager system includes a 210 gallon storage tank and easy to use controller. Our goal is to eliminate the harm from over pumping a well while providing maximum amount of water collection possible from a low yield well. We then deliver water to the home at pressure never experienced before. With over 1000 systems in the field across US and Canada we guarantee more water from a low yield well.

  7. I really like how the hydrogen peroxide option won’t leave any bad after taste. I have been wondering recently what other kinds of chemicals can be used to clean rather than chlorine. I’m so glad that you wrote more about how to treat your water tank and well. I definitely learned a lot.

  8. Hi Robert, I have an old time 250 gal. (estimate) galvanized tank, check valve and pressure switch. The well was not keeping up with my irrigation needs so I installed a 2,500 gallon storage tank with a float ball (no float switch). This worked pretty good, but I had 2 well experts tell me my well is not producing as it should. The pump is 18 years old. I plumbed the storage tank water feed on the galvanized tank side and kept the INLET gate valve to the original tank open and also the gate valve to the green storage tank open. The pressure switch set at 30/50 kept everything working. Since I installed the Pumptec Plus, things are working a bit differently and I am not sure if it is operating as it should. I have everything wired up from the outside electrical breaker panel to the pressure switch (which used to take the MI, M2 wires to the Franklin Control box to the pump), but now, the M1-M2 wires from the pressure switch are routed to the L1-L2 connections on the Pumptec controller with the timer set a #1 and from there, the line goes to the original Franklin control box. However, what is happening is that following Pumptec calibration, the LED display clicks on to SOLID YELLOW and remains there until the RESTART timed duration and then the unit will pump water for about 35 seconds with the PUMPTEC Green Light Flashing. Then, the Solid Yellow LED lights up until the next restart timed restart attempt. All of this time…the Pressure Switch Contacts are ALWAYS in the closed position, even when NOT pumping. So, the system is now being controlled by TIME instead of by PRESSURE. The Pumptec unit is over-riding the former pressure-regulated set-up. One other thing I noted is that even with the Pumptec timer set a setting #1 for a One Minute Restart time, it actually is taking around 5 minutes between Restart attempts. So, it would indicate that the Pumptec Protection system is reading an Under-load condition of the pump and is waiting until there is sufficient current present as indicated by water recharge, even though the timer is supposed to tell the pump to restart in one minute. I appreciate your insights into this. Before I installed the Pumptec unit, my pump would start every 25 or 30 seconds and run for about 20 seconds. It would only take about 5 hours to totally fill up my 2,500 gal. storage tank. At this point I would just as soon bypass the Pumptec system altogether. Will setting the Pumptec timer to the 0 setting effectively bypass the Pumptec functions and allow the Pressure Switch to resume regulating pump ON and OFF activity? Thank You

    1. Very well written and highly informative article. I’ve separately been through the exact same progression in Corvallis MT with a well 485’ deep, set at 470 (not much static level!). I went with a 1500 gallon buried concrete, and the pump protection (although I think mine it a different brand called Coyote), and even get to water my lawn, with a water timer that does 3 sprinklers set to run three times a night, 20 minutes per cycle, 2.5 hrs rest after each 60 minute total set. Runs from dusk till before dawn. I’ve found that to be the best compromise with what the well actually produces, or around August I can eventually outrun my system with watering grass when our valley irrigation use lowers the water table each year in the driest part of the year.

      I never post reviews or comments, but I ended up on your site at the electric fence for poultry article (fox issue a couple of days ago has me looking for solutions beyond a huge run of 6’ tall chicken wire with a perimeter of heave rocks laid on the 12” I placed on the ground), and this one just caught my eye because I have context and was curious. I learned the peroxide alternate, you you helped me here, and i’ll be sure to use your links when I purchase my electric fence stuff from Amazon. I thank you; you richly deserve every referral click!

    How to Save Your Well With Muriatic Acid
    Water wells are used as a water source for livestock, houses, farms and gardens. They are a great way to provide a much-needed resource without the higher costs of public water utilities, but they are not without their own issues. Well screens within the pump area slowly build up with mineral deposits from the water and slow or stop the flow of water. To clear this up, you will need to use muriatic acid to dissolve the deposits.

    Step 1
    Go to the well pump and find the priming plug port just before the pump inlet.

    Step 2
    Measure out a small amount of muriatic acid and pour it down the plug port. The acid eats away at the buildup that is clogging the well screen. Muriatic acid comes in granules for easy application and fewer chemical fumes. A minimal amount of approximately 1/4 to 1 cup is generally all you need. If this doesn’t work, you can always add a little more in a second application.

    Step 3
    Wait approximately one hour to allow the chemical to work. In granule form, it is slow to release. Test the water flow to see if it has improved. If not, continued to test it off and on over the next few hours. You should notice better water flow. If not, then apply 1/4 cup more of the muriatic acid granules to the plug port and wait a while longer.

    1. Muriatic acid is another name for hydrochloric acid (nasty stuff, so let’s all be careful out there), but other than that I don’t know much about this technique. Nor is my well plagued with mineral deposits, but biofilms, which all I’ve really looked into.

  10. It makes sense that the low-yield wells are going to output water much slower than what your needs are. My brother is thinking about getting a new well on his property this month. He needs to make sure it’s installed properly so that he can rely on it for his home’s water supply.

  11. A water stockpiling tank holds clean water from your converse assimilation framework until an interest for water is started in the house or business. Water is siphoned into the tank from the water source, similar to a well or an opposite assimilation framework. The tank aggregates water until it is full. You provide many useful and unique tips. Thanks a lot for sharing the idea’s.

  12. Know this is an older post, but info is still valid.
    I’m using a 500 gallon tank with a Tork EJWT percentage timer, available on Amazon. It sends a 120V (could also do 24V) signal through my float switch to a contactor (<$10) that turns on the submersible well pump. You select the interval BETWEEN submersible well pump cycles from 30 seconds to 24 hours, then select what percentage of that cycle you want to run. I run 5% every 2 hours, so a 6 minute run every 2 hours (5% of 120 minutes). That’s long enough to cool the submersible motor but not so long as to deplete the water column. A benefit is that it avoids water, sand, and gravel cascading/raining down to the motor like the Pumptec system will do and is also very easy on the motor.
    I use a float switch wired as ‘Normally-Closed’ (ON) in the ‘down’ position to stop the Tork timer signal to the contactor when the tank is full. The Tork still sends a signal every 2 hours, it just doesn’t get past the float switch when the tank is full and the float is in the ‘up’ position.

  13. Robert, thank you so much for this information, here on Vancouver Island our water supplies are patchy and unpredictable. We have a very shallow well 13′ which tested out for house purchase at 5gpm in mid September 2017 Well test was fraudulent and not properly performed. Likely 1gpm or less. Of course now in 2021 we have seen increasingly dry/drought summers and our well into summer is increasingly slow. Your article is a life saver indeed and supplies information that none of the other “water information” talks about.
