Why Air Relief Valves Matter
Every pool filter builds up air during operation. If that air isn’t released, it can cause:
-
Inaccurate or fluctuating pressure readings
-
Reduced filtration efficiency
-
Pump priming issues
-
Unsafe pressure conditions in the filter tank
By replacing a worn or broken valve with the Swimables SW-26-908, you keep your filter balanced, efficient, and safe.
Signs You Need a New Valve
Air relief valves are exposed to pressure cycles, chemicals, and the elements, and they wear out over time. Look for these signs that your valve needs replacement:
-
Air bubbles consistently returning to the pool
-
Leaks around the valve housing
-
Difficulty bleeding air from the filter
-
Cracks, brittleness, or corrosion on the valve body
-
Inaccurate or unsteady pressure gauge readings
The Swimables SW-26-908 resolves these problems quickly and reliably.
