I checked the pressure on my Hayward 4030 filtering system, and it's running at 20 PSI, a little higher than yesterday. Normally it runs at 14-16 PSI. The green needle is set to 14, and the red needle is set at 24, and this was set by the pool builder.
I looked at the Hawyward manual and it says the ideal pressure is 7-10 psi. Have I been running at a too high psi level all this time? How do I lower the psi? Should I clean the filters again? (I've already cleaned them only 3-4 weeks ago).
