Pool Check Valve True Union 1-1/4 in

The Hayward TC10125STE is a PVC inline check valve with true union ends for 1-1/4 inch FNPT connections. It prevents backflow in pool and spa plumbing systems where vertical mounting is required. The EPDM seals handle water temperatures from 40 to 140 degrees Fahrenheit. It is rated for 235 psi maximum water pressure at 70 degrees Fahrenheit.

Cracking Pressure 8 psi

The valve opens when forward pressure exceeds 8 psi, making this the critical figure for pump sizing and system design. Below that threshold the ball remains seated and blocks reverse flow. Exceeding 8 psi allows full flow up to 30 gallons per minute through the unrestricted bore. Steam service is not rated for this model.

True Union Ends Simplify Service

The true union connection lets you remove the valve body without cutting pipe, reducing downtime during seasonal maintenance or seal replacement. EPDM seat and seal materials resist common pool chemicals across the stated temperature range. No additional software or accessories are bundled with this plumbing component.

Questions about this item

What does the 30 gpm flow rating mean when the valve is installed in a pool plumbing line?

The valve will pass up to 30 gallons per minute at full flow without restricting the pump or filter circuit.

The FNPT x FNPT connection caps the pressure at what level in daily use?

The threaded joints are rated for 235 psi at 70 Degrees F, so normal pool pressures stay well within that limit.

How much vertical clearance does the true-union ball body need to fit between two pipe runs?

The inline true-union design lets you unscrew both ends for installation, so the valve body itself only needs its face-to-face length between the pipes.
