Pool Drain Check Valve

The Hayward TC10150ST is a 1-1/2 inch PVC check valve designed for pool and spa plumbing systems. It prevents backflow in vertical installations where a single-flow mechanism is required. The true-union body allows easy removal for cleaning or winterising without cutting pipe. Suitable for residential and light-commercial pool equipment pads.

3 psi Cracking Pressure

The valve opens at a cracking pressure of 3 psi, meaning flow begins once downstream pressure drops below that threshold. This low opening pressure suits gravity-fed and low-head pump circuits. The Viton seals and seat resist chlorine and common pool chemicals across the rated temperature range of 40 to 140 degrees Fahrenheit.

Sustained Pressure Rating

Under continuous operation the valve withstands 235 psi water pressure at 70 degrees Fahrenheit. The PVC body and Viton internals maintain seal integrity during extended filter cycles and heater runs. Full-flow design keeps pressure drop minimal so the pump curve is not altered during long duty periods.

Questions about this item

What does the 40 gpm flow rating mean when the valve is installed in a pool plumbing line?

The valve can pass up to 40 gallons per minute of water when fully open, so it will not restrict typical residential pool pump flow rates.

How does the FNPT x Socket connection affect what pipe or fittings can be used with this check valve?

One end accepts a 1-1/2 inch male NPT thread and the other end solvent-welds to 1-1/2 inch PVC pipe, letting you join threaded equipment and plain pipe in the same run.

What space and orientation are required to mount the TC10150ST in a vertical pipe run?

The valve must be installed vertically with flow moving upward, so allow enough straight pipe above and below for the true-union body to be removed for service.
