4" Flanged PVC Wafer Check Valve

The Hayward WCV1400E is a 4-inch flanged PVC wafer check valve designed for inline installation in pool and spa plumbing systems. It provides automatic backflow prevention with a single-flow wafer mechanism. The valve suits horizontal or vertical mounting orientations. Builders and service technicians use it to protect equipment from reverse water flow.

Replaces worn swing or spring check valves

This wafer-style unit replaces older check valves that rely on heavier internal mechanisms or larger body profiles. The upgrade is worth it when space between flanges is limited or when a lower cracking pressure of 1.0 psi improves pump priming. It handles a maximum water pressure of 150 psi at 70 degrees F and delivers a full-flow rate of 315 gpm.

Installs between standard 4" flanges

Installation requires bolting the valve between two mating 4-inch flanges with a gasket on each face; no solvent welding or threading is needed. The compact wafer body fits tight pipe runs where a full-bodied valve would not clear. Common issues include debris preventing the wafer from seating fully and EPDM seal degradation if operating temperatures exceed 140 degrees F.

Questions about this item

Will the 4" flanged PVC wafer check valve fit between standard 4" ANSI flanges?

Yes, the valve uses a wafer-style body with flange-by-flange connections designed to fit between standard 4" flanges in either horizontal or vertical orientation.

What is the correct way to orient the valve during installation, and what do installers often get wrong?

The valve can be mounted horizontally or vertically, but the flow arrow on the body must match the actual water direction; reversing it is the most common error.

How often will the EPDM seat and seal need replacement in a pool system running near 140°F?

EPDM seats typically last several seasons, but at sustained temperatures near 140°F and 150 psi pressure, plan to inspect annually and replace the seat if cracking or leakage appears.
