water temp fluctuating

[jpeterman57]

When using on board water from any faucet in my 2004 Fleetwood Prowler TT 24BH, the temperature fluctuates hot/cold as the water pump cycles on and off.
I've also noticed the water only heats to luke warm regardless of gas or electric operation.
I hope someone can give me a solution.

Re: water temp fluctuating

sounds to me your water heater bypass valves are not right....actually the cross over valve is still open and needs to be closed.

I agree w/ Ken!!! I had the same problem the first year we were full-timing. DH and I had done the winter to summer clothes switch over and all of a sudden the water temps were completely screwy!! It took several days for me to find the bypass valve -- positioned at the bottom of the closet!!! Clearly the process of moving the clothes back and forth nudged the valve to the partially open position! Once in proper position -- we have had NO PROBLEMS!!! Biggest challenge was FINDING the darned thing!!! :laugh:

Usually located right on the back of the water heater.

Thanks Kenneth and Lynn, I'll look for it next time I'm down at the farm and let you know what I found out.
Thanks again.

Removed 4 screws from the inside panel behind the water heater and found two valves at the heater tank. Took a wild guess and turned one off and tried the water. That fixed the problem.
I suppose it had been left in that position from the previous owners winterization.
The space behind the heater is cavernous with just a few wires and waterlines. This space could be utilized for storage or something.
