Product identity

The Hayward TC10200ST is a 2 inch inline true-union check valve made from PVC with Viton seals. It uses an FNPT by socket connection and opens at a 3 psi cracking pressure to allow one-way flow in vertical installations. The valve handles water pressure up to 235 psi at 70 degrees F and operates between 40 and 140 degrees F.

Ideal applications and limits

This valve suits pool and spa plumbing that needs reliable back-flow prevention in a vertical line with a 2 inch pipe size. It is not for systems requiring steam service, horizontal mounting, or a different connection type such as flanged or threaded both ends. Builders needing a higher temperature rating or a non-PVC body should look elsewhere.

Build integration

The true-union design lets the valve body be removed for cleaning without cutting pipe, freeing up maintenance time. It requires a 2 inch FNPT male adapter on one side and a 2 inch socket solvent weld on the other, plus vertical orientation to function correctly. The 70 gpm full-flow capacity supports typical residential circulation pumps.

Questions about this item

What pipe size and connection type do I need to install this 2" FNPT socket check valve?

It fits 2-inch pipe with a female NPT thread on one end and a solvent-weld socket on the other, so you need matching 2-inch PVC pipe and a male-threaded fitting for the FNPT side.

Will this inline true-union valve align with my existing vertical 2-inch PVC plumbing?

The valve is designed for vertical mounting and uses a true-union body, allowing it to connect directly to standard 2-inch PVC pipe and fittings in a vertical run.

How can I verify the valve is sealing properly after installation?

Pressurise the line up to 235 psi at 70 °F; the Viton seat should hold with no leakage, and flow should open once pressure exceeds the 3 psi cracking point.
