In order to achieve maximum output from your filter, regular upkeep and maintenance is required. It is therefore important to understand when your filter requires cleaning. One of the most important part of your pool filter is the pressure gauge. The pool filter functions at low pressure. As the cartridge collects dirt and debris from pool water the flow of water through the pump decreases. Consequently, the gauge pressure rises. When the pressure goes beyond 10 psi which is above the normal pressure, it is time to clean or replace the pool filter.
