Your pool filter requires a lot of pressure to clean water, which you can keep track of with the pressure gauge on top of the filter. You’ll need to check on this measurement periodically to ensure the system is getting cleaned out properly. Learning how to read it will help you provide the correct pool maintenance.

Normal vs. Abnormal Pressure

A pressure gauge will typically range from zero to 60 pounds per square inch (psi). However, there’s no set number to aim for since individual pool pressures vary. The ideal pressure for your filtration system is the number recorded right after having it installed. However, a close second can be read right after changing the filter or thoroughly cleaning the pool. 

During regular pool maintenance, always check the filter’s pressure. If the gauge is 10 psi or more than the normal reading, it is considered high. This is a signal that the filter is not allowing water to flow through quick enough, so it should be cleaned or replaced. 

A too low reading is when the pressure is five psi lower than normal. In this case, the water is unable to reach the filter fast enough and usually indicates a blockage or leak in the system. Avoid this by checking the pump basket and impeller for debris and the main drain covers for blockages. If low-pressure readings cannot be resolved on your own, call a professional pool maintenance service for help. 

How to Relieve Air-Related Pressure

Sometimes increased pressure is a result of air building up in the system, which can occur after the pool has been inactive for a while or the water levels are too low. An air relief valve lets this extra air escape, so water can flow smoothly and the filter maintains optimal pressure. 

Check your air pressure gauge at least once a week, and if you notice it is too high or low, contact the professionals at the family-owned and -operated M & M Pool Services in Honolulu, HI. They provide comprehensive pool maintenance and repair services to all of Oahu.
