I am cleaning my DE filter for the 3nd time since I bought the house last Sept. The pressure was going up slowly until yesterday, when I posted about whether it would harm my filter or pump to have it on at that psi. After I sent the email and kept running it, I continued to check the psi and it went from 18 to about 24 in a couple hours. The pool is pretty dirty after we were on vacation for 3 weeks, definitely I have lost the clarity of the water and it's foggy. I'm working on getting the chemicals sorted as well.
I must've cleaned the pump basket, filter and sweeper bag about 6 times or more yesterday - thinking it was debris and dirt (I have a ton of dirt on the bottom that may or may not be from the dog swimming) and doghair that might be raising the pressure. It didn't really help.
Following some instructions I got from simicrintz the last time I cleaned my filter, I backwashed and the water was clear? Is it supposed to be clean when you backwash?
After the backwash, I popped the top of the filter and took out the panels (can't remember what you guys called them). They came out easily this time (much easier than last time) and I noticed that four or five of them are caked with gunk and the others have nothing on them - including DE. Is the filter supposed to spin in the casing - so in theory all of the panels would get junk on them, right? Anyhow, I popped them out and I'm going to start cleaning them soon but wanted to see if perhaps there is something else I should be checking.
Finally, is it normal that when I turn off the pump, dirty water from the filter would fill it up a bit?
Thanks for all your help. Bruce has been great but I thought I'd give him a break from my incessant questioning. I'm getting close to thinking I need to hire someone to help me get this sorted out and I'd really like to work it out on my own.
