I recently took apart my DE Filter to wash it out. After I put it back together, the back pressure was 10psi, which is about what it normally is after cleaning it, so I was happy. Recently, however, the back pressure has dropped. It's currently 2 psi. I've also noticed that the water is not reaching the top of the clear lid on the pump like it normally would. It only comes up to about a half inch to an inch below the lid. Does anyone know what the possible cause might be?
I was out of town for about two months this summer and while I was gone, my wife asked a friend to come over to clean the filter for us. When I got back I asked him if he recharged with DE powder and he said he did not. I know this can cause damage, and when I took apart the filter I noticed a small tear in one of the grids where a small piece of debris was lodged in it. I had this happen once before (and have since replaced those grids), but that didn't cause low back pressure like I'm getting now. Do you think that may be the culprit this time?
Thanks in advance for your help!
