|Typical floatless valve. There are many brands, all work and look exactly the same|
Floatless fill valves are excellent for farm use. Originally designed for the tank of a toilet, these things are extremely accurate on water level, and operate with no externally moving parts inside the water tank. There are, however, a few gotchas!
1. always install near the bottom of the tank, the max water level allowed is about 2 feet. If you need water deeper than that, just move the valve higher up the side of the tank.
2. Use a standard toilet tank water connector to connect hte supply. This will adapt the weird 5/8 inch thing on the bottom to standard male pipe threads. You can then use 1/2 inch nipple and 1/2" npt to water hose adapter. Simple and dependable.
3. Be sure to install this right! That is the part that took a while to figure out. This valve work on differential pressure.. it compares the pressure of the water level inside the tank to the air pressure outside the tank. To accomplish this, it MUST be installed exactly as shown.
|This is the OUTSIDE of the nut that holds the valve in place. (the other side of the above pic). This side, with all the little compartments, must face away from the wall of the tank. Turn it around and you will go nuts trying to adjust the level.|
