I put a new filter elements in my filter when my pool was replastered about six months ago. There is a large element and small element, just curious if a person should just clean these when the pressure rises or if there is a time frame? The pressure remains very low, around 3 psi. It always has showed low pressure because there's a large surface area. No issues, water is clear, just curious if a guy should be cleaning them on a regular basis or is it all dependent on pressure rise?
