My pool DE filter suddenly has only 5 lbs of pressure when it is usually at 20-25 depending on how recent I back washed. I tried moving the pump in waste mode and backwash mode and the water trickles out of the waste conduit. We did get a sudden abundance of l;eaves in the pool this week as our oak trees are shedding their leaves early this year. How do I determine when the clog is and how do I clear it?
