I opened my pool on sunday. I wanted to get some cya in because we are in the midst of a heatwave. Problem is I need to backwash, the pressure reading went up 10 psi over the normal reading of 15.
i did the sock trick in front of return. Its only been a few hours since I put the sock in. Almost all 4 lbs. is already in pool.
Next question is I replaced my pressure gage because old one broken. Looks to be same type of gage. My question is could you get different readings on 2 different gages? I seem to be about 5 psi over when I first did start up.
