City Water Inlet has a 'check valve' so when using pump water does NOT flow backwards theu the city water inlet connection...otherwise when using pump the water would leak out the inlet
Pump has an internal check valve so when using city water source the water doesn't flow backwards thru your pump
With pump switch on (and water in fresh water tank) the pump will NOT run unless the RV Plumbing System pressure is lower then the pump pressure switch Start set point......
With city water connected and pump RUNS the system pressure is low enough for pump to supply water demands and city water flow is static due to inlet check valve going closed due to pump discharge being hogher then city water source (plus inlet check valve has a spring to assist in closing it)
So either City water supplies the RV Plumbing System OR the Pump sucks water from fresh water tank and supplies the RV Plumbing System
