Pool check valve with Y-pattern body

The Hayward YC10100S is a one-inch socket PVC check valve designed for horizontal or vertical mounting in pool and spa plumbing. Its Y-pattern body allows full flow with a low one psi cracking pressure, making it suitable for circulation lines where backflow prevention is required.

Simple solvent-weld installation

The valve uses socket connections on both ends, so it is solvent-welded directly into Schedule 40 PVC pipe without threading or flanges. The only common issue is applying too much cement, which can restrict the internal seat, and failing to support the pipe on each side, which stresses the joint over time.

Rated for 150 psi at 70 Degrees F

The maximum working pressure of 150 psi at 70 Degrees F is the single figure that determines whether this valve matches your system design; it also operates between 40 and 140 Degrees F with an FPM seal and delivers nine gpm at full flow.

Questions about this item

How can I verify the valve is operating correctly after installation?

With the pump running, confirm water moves freely in the intended direction and that no back-flow occurs when the pump stops; the valve should open at roughly 1 psi cracking pressure.

What comes in the box and what extra parts are needed?

The box contains the 1" socket PVC Y check valve only; you will need PVC pipe, primer and solvent cement to make the socket connections.

Which version should I choose for a horizontal or vertical run?

The YC10100S is rated for both horizontal and vertical mounting, so a single model covers either orientation.
