1/2" CPVC Check Valve Trap for Pool Plumbing

The TC20050ST is a true-union inline check valve built from CPVC with Viton seals. It accepts a 1/2 in FNPT connection on one side and a socket connection on the other. Designed for vertical mounting, it prevents back-flow in pool and spa circulation systems.

Thermals and Pressure Limits

The valve handles water up to 235 psi at 70 Degrees F and operates between 40 Degrees F and 190 Degrees F. A low 3 psi cracking pressure lets flow start easily while the full-flow design keeps restriction minimal during normal pump operation.

Installation Fit and Function

The true-union body allows the valve to be removed for cleaning without cutting pipe. CPVC construction resists common pool chemicals and the Viton seat provides a reliable seal. Vertical orientation is required so the mechanism seats correctly under gravity.

Questions about this item

How do I install the 1/2 in FNPT x Socket CPVC check valve and what step is often missed?

Thread the FNPT end into the female pipe fitting and solvent-weld the socket end to CPVC pipe; the step often missed is orienting the valve vertically so the internal mechanism seats correctly.

What maintenance or replacement will the CPVC check valve with Viton seals need later?

Inspect the Viton seat and seal annually for wear or chemical attack; replace the entire valve if the seat no longer seals at the 3 psi cracking pressure.

At what pressure limit does the valve reach its maximum rating under sustained 70 Degrees F water pressure?

The valve is rated for a maximum of 235 psi at 70 Degrees F; sustained operation at or above this pressure will reach the limit first.
