How to Use a Pool Filter Pressure Gauge and Air Relief - INYOPools

Pressure Gauge. To get a read on this, your filter has a pressure gauge usually found on top of the tank. The gauge has a round face numbered 0 - 60, a needle that indicates the pressure in pounds per square inch (psi), and a clear protective lens. This small part is key to maintaining your filter and therefore your entire pool.
