I'd like to start collecting rain water from at least one barn into a poly tank, then hook it to a tank/float setup. My biggest question is what float is going to give me flow with a small amount of head pressure. Hudson valves list needing 8 psi minimum. Jobe ROJO valves say they work from 0 psi up. Tank would be in the 500-600 gallon range, but it would be mounted only about 4-5 feet off the ground near watering tank. [Reply]   [No Email]

They are cheap, dependable and easy to adjust. Believe it or not, they use them to keep the level right on the devices that fill wine bottles at the smaller wine makers.   [Reply]  [No Email]

Dad would srill the small float hole out a bit bigger when he had 60 cattle, I just use as is for the 25-30 head. With lower pressure, the hole can be bigger and the float will handle it. --->PAul   [Reply]  [No Email]

Costs about $15 and the last one is at least 10 years old. It's totally controlled by the water level and has nothing to do with pressure. cheap float   [Reply]  [No Email]

Adjust, to keep the tank full, but not overflowing. I do this with my herd, about a 1/8" trickle, will keep 6 cows wet, year round, and won't freeze, in all but the coldest weather, here, in MD.   [Reply]  [No Email]
