The Importance of an Air Relief Valve with Gauge
Your filter tank relies on both a pressure gauge and air relief valve to function safely. Together, they allow you to monitor system performance and vent trapped air before it becomes a problem. A faulty unit can cause:
-
Unsafe pressure buildup inside the filter tank
-
Reduced filtration efficiency
-
Air bubbles entering pool return lines
-
Strain on pumps and plumbing components
-
Incorrect system monitoring leading to delayed maintenance
Replacing both components with the Swimables SW-26-900 ensures your system runs smoothly and safely.
Signs It’s Time to Replace Your Valve and Gauge
Don’t wait for complete failure—look for these signs that replacement is due:
-
Gauge needle sticking or not returning to zero
-
Inaccurate or fluctuating pressure readings
-
Water or air leaking around the valve
-
Valve difficult to open or close
-
Visible cracks, corrosion, or fogging inside the gauge lens
The SW-26-900 combo unit solves all these issues in one simple installation.
