I thought I would start a new topic, since my last topic on low waterflow and air in my pump basket that I started is no longer relevant as the issue was solved by removing the filter..
Anyways, to expand on what we found out in the previous topic..I have a cartridge filter for my pool. Recently moved into the house and am in the shock process of getting rid of algae. pool is at the point of being nice a blue, with it being a bit hazy and hard to see the drains in the 5 ft deep area...but otherwise looking great compared to the beginning of the week.
I have not been able to get my pressure below 20 psi since I moved in and had HORRIBLE water flow..basically none, so I finally found the problem with the help of my other topic and it was the filter..it looked clean and I had sprayed it off several times before, but I soaked it last night in dishwasher detergent (maybe didn't use enough?) to try that and now with it clean it is reading 8 psi when I run the pump...huge difference compared to what I was used to seeing!
All good and great, but after 30-45 minutes the pressure slowly rises up to 18-20 psi, and my flow starts falling to basically nothing again. I have cleaned the filter 3 times today and been monitoring it. I take it out and it looks ALMOST as clean as it was when I put it in..if I put it back in without cleaning, I get the same 20 psi, but if I clean it again (spray it down really good) im back down to 8 psi...What am I missing? Can it be getting plugged up that fast, especially since I can't even see what is plugging it? Spraying it down seems to do the trick, but like I said it only helps for about 45 minutes, then I am out there cleaning it again.
Maybe this is normal through this process and others have had to do the same thing, but I haven't read anything on that when searching so I need to figure out why it is doing this.
