Pool check valve for flow control

The Hayward TC20075STE is a true-union ball check valve built from CPVC with EPDM seals. It installs inline on 3/4 inch FNPT-by-socket piping and opens at a 3 psi cracking pressure. Vertical mounting orientation is specified for correct operation.

True union eases service and replacement

The union ends let installers remove the valve body without cutting pipe, reducing downtime during maintenance. EPDM seat material handles chlorinated water and typical pool chemicals through the rated temperature range of 40 to 190 degrees F. Full-flow design passes 10 gpm without restriction.

235 psi pressure rating at 70 degrees F

This maximum water-pressure figure decides whether the valve suits the system head and pump curve. Steam service is not rated, so the part must not be used in steam lines. Buyers who need higher pressure tolerance or steam-rated construction should select a different valve.

Questions about this item

How often will the EPDM seals in this TC20075STE check valve need replacement under normal pool service?

EPDM seals typically last several seasons in chlorinated water at temperatures up to 190 Degrees F; inspect annually and replace if cracking or leakage appears.

What is the first performance limit reached when this 3/4" CPVC valve runs continuously at maximum flow?

The 10 gpm full-flow rating is the primary hydraulic limit; sustained operation above this rate increases pressure drop and may accelerate seat wear.

How much heat does the valve body generate when water at 70 Degrees F flows at 10 gpm all day?

The CPVC body adds negligible heat; fluid temperature rise is dictated by the system, not the valve, and the valve is rated for continuous service up to 190 Degrees F.
