Checked the water booster pump. The pump is locked up, going off on thermal overload. I checked the water pressure before the backflow device. I replaced a pressure gauge on test port#1. The reading is at 50 psi. I had Jeff flush some toilets the pressure dropped to 45 psi before the backflow. That is telling me that after the backflow system, the water supply pressure is at 40 to 38 psi. The building should be fine at that pressure. The booster pump was installed years ago when Lemont had low water pressure. If I remember right, it was at 20 psi before the back flow, which is why the pump was put in. I bypassed the pump and turned the switch off to the pump.
