Is there a return line to the fresh water tank with a return valve? And if so, where is it located??? Was hooked up to city water for 7 months in Las Vegas, but ran the pump once a month to exercise it. Problem did not start until started driving again.
Losing hair over this one.  |
From the Shurflo troubleshooting section:
- Are the valves held open by debris or is the rubber swollen?
- Pressure switch operation. By-pass set higher than shut-off.
So take it apart to see if debris is inside which would allow the H2O to return to the tank. As for the by-pass setting, you will have to read the applicable manual.
Good luck!
