elibedarn Report post Posted September 3, 2022 (edited) Fresh water tank will not accept water input? Thinking maybe the inlet valve was defective so I by passed that with a new hose inlet creating a direct input by passing the off on valve. Do animals, bugs, etc, bed in over flow tubes possibility causing an air lock. I am going under the rig tomorrow to see if I can access the tank. It is not under the bed. Do you ever clean your RV overflow pipes? My RV fresh water tank has 2 over fill drain hoses. I have never seen how overflow pipes work. I check if the tank is full by physical check at the overflow pipe but that is it. Wondering if they have check valves in the tubes that may go bad?
