I need to know if you can help me with a question I have about my pressure. When I start my pool up in the summer my pressure gauge reads at about 10 psi, but I get a lot of air when my main drain and both skimmers are open. I use the recommended amount of d.e.. But when the pressure gets to about 18-20 psi I can ope all 3 and no air bubbles.
When it is at 10 psi the pressure of the water coming out of the return is huge and you can't even be next to the return it almost hurts on the skin..Do I need to increase my amount of d.e to start up at a higher psi. Can't figure out how to keep the psi at 18 or above because if I try to backwash it goes back to 10 psi and I have to run the pump along time to get up to 18 psi.....
