Which Best Float Valve Kit For Your Water Pressure?

Which Best Float Valve Kit For Your Water Pressure?

The Best Float Valve (aka Watson valve) is the most durable and simple livestock water tank float valve on the market. They are full-flow valves that are almost impossible to clog up. The arm is made of steel instead of flimsy brass, and the float is aluminum with a chain or pigtail rod to attach. We have no plastic pieces anywhere in any of our kits. There is no minimum pressure requirement for any of our valves. They will operate properly even with water pressure that won't trip the gauge.

Our valves come with 3/4”, 1”, 1 1/4”, or 1 1/2” pipe fittings. The mini valve is 1/2". The regular valve flow is 13 gpm on a 1 ½” line at 5 psi and 50 gpm on a 2” line with 45 psi. There are various stainless steel options, and all but the mini valves can be ported and plugged for ice prevention or continuous flow.

Our mount kits are designed to attach to the 3/4" valves. While the mount kits can handle a good amount of pressure, some of the pressure capacity is lost when they are used. If you are pushing 90 psi, we recommend pairing the side mount with a High Pressure Premium Kit to function best. 


These valves come in 1 1/4" & 1 1/2" and will handle twice the amount of volume flow as our regular water trough float valve kits. On a 1 ½” pipeline with gravity flow at 5 psi, our high volume valve flows up to 26 GPM. On a 2” pipeline at 45 psi, our high volume valve flows up to 110 GPM. They can also be ported for ice prevention or continuous flow. We also have a High Volume Valve Mount Kit that was designed to connect to our high volume valves. As stated before, our valves don't have a minimum pressure needed to function properly.

For colder climates, check out our MicroSweeper. We also have a Bleeder ValveExtension Kits for continuous flow. These products can be added to any ported valve. We have other Float Valve Kits available. And if you have questions, we would love to help you! Let us know today.
