Host Mammoth Question.

Thanks for the info Brinson! I've had my Mammoth for over a year and honestly did not know that the city water valve needed to be in the shut position when using city water. To clarify, I have 2 low point valves, a water tank drain valve (all 3 marked), and I believe the valve on the vertical PEX pipe just to the right of the pump is the city water valve. Yours appears to be marked and mine isn't. From you post, you may have labeled the valve yourself. I am correct in my assumption? Nothing in the owners manual.
