Description

The Hayward 4-inch PVC Socket True-Union Y-Strainer (YS10400SEU) is built for high flow and high demand environments. With true-union socket ends, you get simpler maintenance access without disturbing pipe alignment. The EPDM O-rings ensure the unit remains leak-tight even under chemical exposure. Rated for 150 psi non-shock at 70°F, its sturdy PVC body and standard 1/32″ screen protect downstream equipment from debris, while maintaining strong flow. Whether used in commercial pool systems, industrial water handling, or heavy municipal applications, this strainer delivers performance and durability.

Pro Tip

When installing, orient the screen downward and install a shut-off upstream to facilitate cleanouts. Keep a finer mesh screen on hand for times when the water condition worsens. Always check and lubricate the EPDM seals when servicing to avoid leaks. Use solvent cement rated for PVC socket joints to ensure proper bond.
