2013 3150RL - I have water getting by the valve that lets you select between your city water hose connection to the RV. Normal position applies pressure to the trailer and Fill position routes water to the fresh water tank. Over time with the valve in the Normal position to go to the trailer, water will start coming out of the fresh water overflow. As the valve is not working correctly I would like to replace it.
Can someone help with the correct nomenclature for the valve so I can search??
