Now, I'm curious. I'm trying to think of how the water circuitry is designed, such that you can access the same distribution system from city water and also with the RV's water supply,....without a selection valve. There has to be at least a shutoff valve where you connect the city hose.
I don't know for sure but logically thinking I think they work without a shutoff valve because the city water connection is on the other side of the pump. I assume the internal water pump valves are one way only so when the city water is connected the pressure will shut those preventing water from going through the water pump and backfilling the fresh tank. However, if this is the case I don't know what prevents pumped water from exiting the city water connection when city water is not in use. Perhaps there is a one way valve on that line. Our other RV has all the lines exposed and I don't see a valve on that one either. Now I'm curious on that too!
