Watts PB1 Float Valve, Glass-Reinforced Nylon

The Watts PB1 is a 1" pilot-diaphragm tank and reservoir fill valve that runs at full flow until it shuts off, cutting pump wear on large pump-fed tanks. It features a glass-reinforced nylon body and a buna-n seat.

This 1 inch tank valve has a very large flow rate. It utilizes a differential dual weight system that reduces pump wear and saves electricity. This valve is diaphragm activated and has a steel pin that runs inside the pilot center which acts as a self cleaning mechanism which is unique to Apex valves.

Features

• Designed to help control water levels and prevent backflow in water tanks
• Features a large flow rate
• Built for durability and long life using UV-stable fiberglass-reinforced nylon and Acetyl (POM)
• Fully serviceable for long-term use

Common Questions

Does this include the float ball and rod?

Yes. This valve has an integral float and installs complete; there is no separate float ball or 3/8"-16 rod to buy, unlike the Watts bronze lever-arm float valves.

Can I use it on drinking water?

No. This valve is not certified lead-free and is for non-potable service only — cooling tower and refrigeration make-up, irrigation, livestock watering and tank fill. Do not install it on a potable water supply.
