The pressure in the home is not sufficient enough to properly run the sprinkler system. The pressure is at 60PSI on the front hose Bibb. The pressure drops to 18-22PSI whenever the sprinklers are ran. At first, it was believed that the regulator was bad. The current regulator was installed Feb 2023 by Southside Plumbing. A different regulator was installed today and the same results occurred. The pressure could not be raised over 60 with a regulator on the main. The regulator was removed all together and the pressure is now at 62PSI in the same location. Without the regulator, the pressure drops to about 45-50 PSI when the sprinklers are ran. The home was left without a regulator installed.
