A pool filter should have a pressure of approximately 1-1.2 BAR. Anything over 1.2 BAR  is considered high pressure and can damage your pool equipment. To resolve the issue and bring the pressure back to normal, check for the following: Clogged filter. This is the most common issue when it comes to excessive pressure. Over time, the filter can get jammed up with fine debris, chemicals, and oils. Removing larger debris does not free the filter of these other materials. Use a filter cleaning products to restore the normal water flow. Clogged breather tube. Filters often have a tube designed to automatically expel air trapped at the top of the filter. If this tube becomes jammed, high pressure results. Check this tube and clear it if necessary. ( Some filters may not have this due to special designs) Suction air leak. A large suction leak may cause the pump to lose prime before the pressure builds up. But in the
