What this check valve does

The Hayward TC10050STE is a PVC inline true-union check valve with a 1/2 inch FNPT by socket connection. It allows flow in one direction while preventing backflow in pool and spa plumbing systems. The valve body uses PVC construction with EPDM seals rated for water temperatures between 40 and 140 degrees Fahrenheit.

Pressure and flow limits

Maximum water pressure is 235 psi at 70 degrees Fahrenheit and the valve is not rated for steam service. Cracking pressure is 3 psi with a full-flow design rated at 6 gpm. Vertical mounting orientation is required for proper operation and the seat material is EPDM.

Installation notes and common issues

The true-union design lets you remove the valve body without cutting pipe, but solvent-weld sockets and FNPT threads need clean, square cuts and compatible sealant. Over-tightening the union nuts can crack the PVC body and debris on the seat will prevent a tight seal.

Questions about this item

Should I pick the 1/2 in FNPT socket version or another size for my plumbing?

This model is built for 1/2 in FNPT x Socket connections; match it to the same pipe size in your system for a proper fit.

What does the 3 psi cracking pressure mean once the valve is installed?

The valve begins to open when upstream pressure exceeds 3 psi, allowing flow in one direction while preventing backflow.

How does the FNPT x Socket interface limit pressure at 70 Degrees F?

The PVC body with FNPT x Socket ends is rated for 235 psi at 70 Degrees F, so do not exceed that pressure at that temperature.
