Put handle in NORMAL City water position. Do you have City water at the faucets inside? This is the first thing to do. Maybe the fill inside water filter screen is clogged if you get no City Water inside. Also, this system may also have a Check Valve that is stuck. Doug
That is a three way ball valve and they do go bad. I have one right now on my coach that started acting up. When I am hooked up to city water, it has a small leak to where it is also filling the big fresh water tank and before I new it, I saw that there was a small drip coming off the over flow hose under the coach. So I looked up the part and if you get the original it runs close to four hundred dollars. So when I get a chance to change it out I am just going to replace it with a three way valve for water. It should work and for a cost of only around thirty dollars.
