Pentair Valve & Gauge Assembly for System 3 Filters | 24850-0105

Description

The Pentair Valve & Gauge Assembly (24850-0105) is the OEM replacement air relief valve and pressure gauge kit for Pentair (formerly Sta-Rite) System 3 Modular Media, Sand, and D.E. Filters.

IMPORTANT: THIS IS A MULTI-PIECE KIT, NOT A SINGLE COMPONENT
This listing is one complete Valve & Gauge Assembly, sold as a kit. It includes the 2 in. pressure gauge, air release valve, nipple, adapter bushing, and O-ring — not an individual gauge or valve alone.

This assembly combines the filter tank’s air relief valve, 2 in. pressure gauge, nipple, and adapter bushing into a single replacement kit. It lets you purge trapped air from the filter tank and monitor system operating pressure from the same top-mounted location, so a worn or leaking valve or a stuck/inaccurate gauge can be corrected in one service action.

Fits Into

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

When you replace this assembly, check the gauge reading with the pump off and the system fully depressurized — it should read at or near 0 psi. A gauge that won’t return to zero, or an air relief valve that continues to weep water after the manual purge is closed, points to a failed O-ring seal at the valve base rather than a bad gauge, and this kit resolves both in one part.
