Hey everyone. New here. I have a Hayward DE filter that's tired(10 seasons), and looses pressure after about 15 minutes of use requiring me to go "bump" the pressure. When I do that, its fine for another 15, all the while the pump has stayed on and running seemingly smooth. Do I just need a new filter? Or do they go hand in hand? Its really a pain to take apart the filter and clean off the tenticles. Any input would be appreciated!
