Pool plumbing check valve

The Hayward TC20075ST is a CPVC inline true union check valve with FNPT and socket connections for 3/4 inch pipe. It uses a Viton seal and a single flow-design mechanism that opens at 3 psi cracking pressure. The valve is rated for 235 psi water pressure at 70 degrees F and handles temperatures from 40 to 190 degrees F.

Suitable for vertical pool lines

This valve installs vertically in pool and spa circulation systems where back-flow prevention is required and CPVC chemical resistance is specified. It is not for horizontal runs, steam service, or installations that demand a lower cracking pressure or a different body material such as PVC or metal.

Sustained pressure and temperature performance

Under continuous operation the CPVC body and Viton seat maintain sealing integrity up to the 190 degree F limit and the full 235 psi rating at 70 degrees F. The 10 gpm full-flow capacity remains stable without the pressure drop spikes that can occur during brief start-up surges.

Questions about this item

What pipe size and connection type must my existing plumbing have to fit the 3/4 in FNPT x Socket check valve?

Your plumbing must be 3/4 inch nominal size with a female NPT thread on one side and a solvent-weld socket on the other to match the valve's FNPT x Socket connections.

Can the CPVC valve rated for 235 psi at 70 Degrees F handle the pressure from my older schedule 40 PVC pump line?

Yes, standard schedule 40 PVC at 70 Degrees F is rated well above 235 psi, so the valve's 235 psi limit will not be exceeded by the older line.

How can I confirm the valve is operating correctly after installation?

Run water through the line; flow should pass freely in the forward direction and stop completely when the pump shuts off, showing the 3 psi cracking pressure is sealing properly.
