Pool Filter Pressure Gauges
Use pressure gauges on top of your pool filter or on a pool cleaner line. When filter pressure is 8-10 lbs over the clean, start up pressure, backwashing is indicated. Vacuum gauges, required on some commercial pools, are used before the pump, to measure the suction and can indicate a clog in the impeller, pump basket or plumbing line.
A pool filter pressure gauge is one of the most important pieces of equipment and one that you should look at very regularly. Sand filter pressure gauges usually have a back mount connection, although a bottom mount will suffice in many cases. DE and Cartridge pool filter pressure gauges are usually bottom mount, with the connection on the bottom, rather than the back of the gauge. Pool pump pressure gauges are a vacuum gauge, when threaded in place of the pump basket drain plug, will measure pump suction, displaying a vacuum reading.
