My livestock water is pumped out of a brook that have the usual kinds of crud in it -- bits of plant matter, bugs, silt, etc. These tend to clog livestock waterers and also the foot valve at the bottom of the inlet pipe. Sure, the foot valve is screened, sort of, but the screen is too coarse, and sometimes I have to pull the twigs and crud out of it.

So I got tired of this and looked for a finer screen. My eyes fell on an old orange string glove. Bingo! I pulled it over the foot valve and held it on with a zip tie. The water is running cleaner and the foot valve probably won't clog for a year.

This is probably the weirdest improvised repair I'll do all year.

Update, August 15, 2009: The glove clogged with silt and I removed it. It didn't look a lot different when clogged, so I'm going to replace it with something that looks a lot different when clogged -- window screening, perhaps. It sure worked while it lasted, though!
