I cleaned my Hayward DE filter about a month ago as I noticed the pressure was zipping up to about 20 PSI when 10 PSI is normal. By cleaning I mean disassembled and sprayed out with a hose. I then added the right about of DE in the simmer (4lbs) and all was normal for about 2 weeks. Then I noticed again the pressure shooting up again. So Backwashed for about 1 minute and without adding DE just turned it back on. Was fine for about another week then again pressure starting shooting up. That was last night. Backwashed again and pressure back down to 10 PSI. Now this morning less than 12 hours later pressure was all the way up to 30 PSI. A quick backwash and it came back down but its already climbing again.
Why does my pressure keep going up like this?
Thanks for any help.
