FAQ’s about the All Plastic Float Valves

Q. How does the all plastic float valve work?

A. This valve has a chamber. Inside this chamber is a cylinder with holes around the top, and below the holes is an O-ring. When the valve is open, water enters the chamber and flows through the holes into the cylinder and out through the bottom of the valve. When the tank is full, the float is pushed up by the level of liquid in the tank it lifts the cylinder. The top of the cylinder with the holes slides into the cavity, and the O-ring seals it off. This stops the flow of water through the valve.

Q. How do you mount them?

A. There are four threaded mounting holes in the top of the valve.

Q. How do you connect them to your water line?

A. You can use rigid piping and go over the wall of the tank using two 90° elbows, or you can run your piping through the wall of the tank using a bulkhead fitting.

Q. Where is the inlet on the valve?

A. The inlet is on the side of the valve opposite the float. The inlet is a female national pipe thread.

Q. Where is the outlet on the valve?

A. The outlet is on the bottom of the valve at a 90° angle from the inlet.

Q. What is the overall length of the valves, including the float?

A. The 1/4", 3/8", and 1/2" are 12.63" long and the 3/4" and 1" are 15" long.

Q. What is the diameter of the float?

A. The 1/4", 3/8", and 1/2" are 4.5" in diameter and the 3/4" and 1" are 4.75" in diameter.
