Low Water Pressure
When connected to city water the inside water pressure starts off good then drops. It drops fast. When using tank water and the pump, the flow rate is fine. I checked/cleaned all the aerators and filters on the faucets. It's not that. The pressure regulator is at 55/psi. All the screens looked cool. I measured the flow rate from the hose and filter which was 5.6/gpm. Inside the coach, I removed the cold water hose from the faucet, using that as the source to test the flow rate in the coach got 1.1/gpm. Got about the same from the faucet when I reconnected the cold water. Taking into assumption that modern faucets flow at 1.8/gpm I don't expect the 5.6/gpm. Would be nice though. Where am I loosing the pressure? How do I fix it? It would be nice to take a shower and actually get wet in a timely manner.
