If you have the same light switches as our 2011 Bus I find we are always turning the water pump on by accident. I wrote Tiffin and suggested they either remove the water pump switch from the light switch panel or install a separate pump cutoff switch.
I would frequently see that the red water pump light was on in the service bay and we were connected to shore water with no need for the pump to be on.
I went to the outside service bay and cut one of the electrical wires leading to the water pump then installed a single throw (OFF /ON) switch in the circuit. Now regardless how many times I accidently turn the pump on by hitting the wrong switch on the light panel the pump won't come on unless I turn it on outside.
