Pool check valve for CPVC systems

The Hayward TC20100STE is a true-union check valve built for 1-inch CPVC piping. It suits pool and spa installers who need reliable back-flow prevention in vertical lines.

3 psi cracking pressure and 18 gpm flow

The valve opens at 3 psi cracking pressure and delivers a full 18 gpm flow rate when open. This single figure decides whether the valve matches the pump curve and system head of the installation.

True-union socket and FNPT ends simplify service

The inline true-union design lets the body be removed without cutting pipe. Install vertically with flow upward; the EPDM seals handle 40 to 190 degrees F and 235 psi at 70 degrees F.

Questions about this item

What does the 18 gpm flow rating mean when the valve is installed in my plumbing system?

The valve allows up to 18 gallons per minute of water to pass through when fully open, with a cracking pressure of 3 psi to start flow.

How does the FNPT x Socket connection limit the pipe sizes I can use?

One end accepts 1 inch female NPT threads and the other end fits 1 inch CPVC socket, so both connections are fixed to that size.

What clearance is needed to mount this check valve vertically?

The valve must be installed in a vertical orientation; allow enough straight pipe run above and below for the true union body to be assembled and serviced.
