1/2" PVC Check Valve

The Hayward TC10050ST is a true-union inline check valve built for 1/2-inch FNPT and socket connections. It suits pool and spa plumbing where automatic back-flow prevention is required. The Viton seals and PVC body handle chlorinated water without degrading.

Thermal and pressure limits

Rated for continuous operation between 40 and 140 degrees F, the valve withstands 235 psi at 70 degrees F. A low 3 psi cracking pressure lets flow start with minimal head loss. Full-flow design keeps restriction low during normal circulation.

Upgrade and replacement scope

Replaces worn swing or spring check valves that leak or chatter in vertical lines. The true-union ends allow removal without cutting pipe, saving labour on service calls. Not suited for steam lines or systems exceeding the stated pressure and temperature envelope.

Questions about this item

How do I install the 1/2" FNPT socket check valve and which step is often missed?

Apply thread sealant to the FNPT end, solvent-weld the socket end, and orient the valve vertically so the arrow points up; the step most often missed is the required vertical mounting orientation.

What maintenance will the Viton seals need later?

Inspect the Viton seat and seal annually for swelling or cracking caused by chemical exposure; replace the seal kit if leakage appears at the union or seat.

At what pressure limit does the valve reach its maximum rating under sustained use?

The valve is rated for 235 psi maximum water pressure at 70 °F; sustained operation above this pressure will exceed the design limit.
