Proper air relief is essential to safe and accurate pool filter operation. The Swimables Pentair Style Air Relief Valve with Pressure Gauge (SW-26-900) is a direct replacement designed to safely release trapped air from the filter tank while providing a clear, accurate pressure reading for Pentair-style pool filters.

During system startup and after filter cleaning, air becomes trapped inside the filter housing. If that air is not released, it can compress and lead to inaccurate pressure readings, inefficient filtration, and unsafe operating conditions. This replacement air relief valve restores proper venting and pressure monitoring so the filtration system operates exactly as intended.

The SW-26-900 combines a manual air relief valve with an integrated 0–60 PSI pressure gauge, eliminating the need for separate components. Manufactured for durability and precise fit, it is ideal for routine maintenance, service repairs, or replacement of leaking or unreliable original assemblies.

Safe Air Release and Accurate Pressure Monitoring

This air relief valve allows controlled venting of trapped air during startup, ensuring pressure stabilizes before normal filtration begins. The integrated gauge provides continuous system feedback, helping establish a clean-filter pressure baseline and monitor performance over time.

Durable Replacement for Worn or Leaking Assemblies

Original air relief valves and gauges can crack, seize, leak, or give inconsistent readings due to chemical exposure and pressure cycling. The Swimables SW-26-900 restores dependable operation without requiring filter lid modifications or additional fittings.

Compatible with Multiple Pentair Filter Models

The Swimables SW-26-900 is engineered to fit Pentair-style filter lids commonly used on residential and commercial pool systems.
