Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Poolaroo Pro Tip

Before installing, cut the inlet tubing cleanly and squarely — a clean cut ensures a secure, leak-free connection on both ends of the valve. Confirm the flow direction marked on the valve body aligns with the direction of flow in your feeder line before finalising the installation.
