Using fresh water tank now and pressure is good. Tried with & without pressure regulator & still no flow in the camper. 99% sure it's on the camper side. The backflow check valve moves in and out easily. It almost has to be in that check valve though right?
Sounds like the check valve on the inlet since you have good pressure with the demand pump. I would also make sure it is not the CG water. You may have good flow with the CG water but the pressure might be very low and once there is a restriction it drops even lower. Has this happened at other CG's?
