Proper air release is essential for safe, efficient pool filter operation. The Swimables Purex-Style Air Relief Valve for Pentair Pool Filters (SW-26-207) is a direct-fit replacement designed to restore reliable air purging on Pentair Purex-style filter systems.

This air relief valve allows trapped air to escape from the filter tank during startup, maintenance, or normal operation. When an air relief valve becomes clogged, cracked, or stuck, air can remain trapped inside the filter, leading to pressure issues, reduced circulation, and unnecessary strain on equipment. Replacing it with the correct Purex-style valve helps maintain stable pressure and consistent water flow.

Manufactured to OEM-equivalent specifications, the Swimables SW-26-207 provides dependable performance and fit without the higher cost of factory-branded parts.

Restores Safe Air Release and Stable Pressure

Air buildup inside a filter tank can reduce filtration efficiency and cause pressure fluctuations. This replacement valve allows air to be safely released, helping the system reach proper operating pressure quickly after servicing or startup.

Consistent air removal supports smoother circulation and protects internal filter components.

Designed for Pentair Purex-Style Filters

The SW-26-207 is engineered specifically for Pentair filters that use a Purex-style air relief valve. Proper threading and sealing surfaces ensure a secure installation and reliable seal, reducing the risk of leaks or improper air release.

Using the correct valve style is critical for maintaining filter safety and performance.

Durable Construction for Pool Environments

Air relief valves are exposed to constant moisture, pressure, and pool chemicals. This replacement valve is made from durable, chemical-resistant materials designed to hold up in outdoor pool equipment environments.

Its simple, effective design ensures smooth operation and long service life with routine maintenance.

Why Replacing a Faulty Air Relief Valve Matters

A worn or non-functioning air relief valve can compromise both performance and safety.

• Allows trapped air to escape safely
