Shurflo water pump

In our 2021 320 CS, we found the water pump would continue to run after pressurizing. The Shurflo pump has an Allen wrench set screw on the pressure switch; turning it about 90 degrees clockwise (as viewed from above) solved the issue.

    Thanks, I've never considered adjusting the pump.
    Mine is mounted upside down . . . so adjusting will be a project day activity.

    I did do some additional web-research and these two items might be helpful:

    A]   Good video on Adjusting Series 4000 Pump

    B]   Bits and pieces of the installation manual
