3 in Socket PVC Check Valve

This Hayward TC1300S is a 3 in inline true union check valve built for pool and spa plumbing. It uses a PVC body with Viton seals and a single flow design that opens at 3 psi cracking pressure.

Suits vertical flow lines up to 150 psi at 70

The valve handles water temperatures from 40 to 140 Degrees F and delivers 150 gpm full flow. It is not rated for steam service, so installers needing steam rated components must select a different valve.

3 psi cracking pressure

This fixed opening pressure decides whether the valve will operate correctly in your circulation system. Verify the system head before purchase because the cracking pressure cannot be adjusted.

Questions about this item

What does the 3 psi cracking pressure mean for flow direction?

The valve opens when upstream pressure exceeds downstream pressure by 3 psi, preventing backflow until that differential is reached.

What pipe size and joint type does the 3 inch socket connection require?

It fits 3 inch Schedule 40 PVC pipe; each end is a solvent-weld socket so you prime and cement the pipe directly into both ends.

How do you install the true-union body without stressing the pipework?

Unscrew both union nuts, solvent-weld the tailpieces into the pipe, then thread the nuts back onto the valve body — do not glue the nuts themselves.
