Ok I took the plunge and cleaned the filter myself. It is a DE Natilus filter. I took it all apart and boy did it have a lot of built up DE inside. So got it all cleaned off, cleaned each grid and all parts. Pulled out the drain plug and it has what looked like a black seal on the inside. So I took the plug out so the remaining dirty water in the bottom of the pump could drain. So got it all put back together and have some questions.
1. My pressure is in between 0 and 10. This is the first time for a full take apart. Usually when I backwash my pressure drops down a little below 10. So I assume this pressure between 0 and 10 for a full take apart is ok.
2. Second question is when I put the drain plug back in I made it as tight as I could. Around the drain plug there is a slow leak. What do I need to do to fix this? Do I need to pull a sealant around the inside of the plug or do I need a new one?
3. I got it all put back together and I have 4 places around the top and bottom that are leaking. Is this the sign that I need a new round seal or is there something else I need to do? I took it apart and put it back together and still have the leaks. I thought maybe I had not got something tight enough but it did it again the 2nd time around as well.
4. Also having a hard time determining how tight to put the screws around the metal round part that you put on last.
If pictures would help I can get pictures as well.
Thanks for all the help.
