About This Item
The Hayward Stand Pipe and Underdrain Assembly (VLX4001A) is the OEM replacement stand pipe and underdrain assembly for compatible Hayward sand and valve-on-top filter systems.
What It Does
The stand pipe and underdrain assembly forms the internal collection and distribution core of the filter tank. The underdrain sits at the base of the filter vessel to support the filter media and collect filtered water, while the stand pipe channels that water upward to the valve and return line. Replacing this assembly restores the filter's internal flow path when the existing components are cracked, broken, or otherwise compromised.

Poolaroo Pro Tip
Before ordering, confirm the part number against the exploded diagram in your filter's installation manual or on the original part itself. Stand pipe and underdrain assemblies vary by tank diameter and valve-port configuration — an incorrect assembly will not seat properly and may allow unfiltered water to bypass the media. Consult manufacturer specifications for confirmed model compatibility if your filter model is not listed above.
