Pool Filter Pressure Too High - Now What?

From https://www.swimmingpoolsteve.com/pages/filter-pressure.html this video talks about what to do when your pool filter pressure is too high. First, the system can operate anywhere from zero to 30 PSI safely. Every pool has a unique number for your "normal" filter pressure. Generally, your normal filter pressure, or "clean operating pressure" as we call it, is the baseline for determining when to clean your filter. When your filter pressure rises 7 PSI above your clean operational pressure then it is time to clean your filter media. This should resolve high pressure and reset you to the clean operational pressure again.

Sand filter tip - Run the filter in recirculate mode which bypasses the filter media. If the filter media is the problem, the filter pressure will reduce a lot when you run in recirculate. If this does not improve the filter pressure, then the problem is not with the filter media.

Cartridge filter tip - When you clean a cartridge filter you must soak in a degreaser to remove the oils which are saturating the paper. It is not usually the physical debris that causes problems with high pressure, but the paper becoming saturated with sweat, oils, makeup, sun tan lotions etc. and a degreaser is needed to break this up. If you only rinse your filter without a degreaser soak, your filter pressure will continue to be high. Also, ever use a pressure washer to rinse paper filters. This drives the debris deep into the paper and will ruin your filters.

Faulty pressure gauges cause a lot of problems with high filter pressure. Test yours by removing it from the system. It should reset to 0 PSI when removed. If it says any number other than zero then it is garbage and can not be repaired. Replace with a new one.
