    Water pressure

    What PSI # does GD recomend should I adjust my water pressure regulator to? To avoid damage internally.

    I use an adjustable pressure regulator and keep it between 45 and 50 PSI. I believe the systems are tested to over 100 PSI, but I don't want to tempt fate.

    We run 45 psi on our pressure regulator and have had no issues.

    I set my adjustable regulator at 40. No issues, and there is enough pressure to shower in comfort.

    I set ours at about 55 psi. No issues so far. However even at that level the pressure is way too weak.
