1/2" PVC Y Check Valve for Pool Plumbing

The Hayward YC10050T is a 1/2" threaded PVC Y-pattern check valve designed for pool and spa drain lines. It uses an FPM seal and seats rated from 40 to 140 degrees F. The valve cracks at 1.0 psi and handles up to 150 psi water pressure at 70 degrees F.

Suited for Low-Flow Horizontal or Vertical Runs

This valve suits installations needing a compact Y-body that mounts horizontally or vertically with a full-flow 0.8 gpm capacity. It is not for steam service, high-temperature lines above 140 degrees F, or systems requiring a cracking pressure different from 1.0 psi. Buyers needing larger pipe sizes or metal bodies should look elsewhere.

Simple Threaded Installation

The FNPT x FNPT threads connect directly to 1/2" pipe without special tools. The Y-body allows horizontal or vertical mounting, but debris in the line can prevent the seal from seating fully. Over-tightening the PVC threads risks cracking the body, so hand-tight plus one turn is standard practice.

Questions about this item

What size threaded fittings do I need on my existing pipework for the 1/2" FNPT connections?

The valve has 1/2 in FNPT x FNPT ends, so your plumbing must provide matching 1/2 in male NPT threads on both sides.

Will the 1.0 psi cracking pressure allow flow from my low-head pump without stalling?

The valve opens at 1.0 psi, which is low enough for most residential pool pumps operating around 70 Degrees F and 150 psi max water pressure.

How can I confirm the FPM seals are holding after I install the YC10050T?

Pressurise the line to working pressure and watch for leaks at the threaded joints and valve body; no seepage means the FPM seat and seals are sealing correctly.
