We just brought our newly purchased 2008 Pleasure-Way Lexor home yesterday. While testing the hot water heater, we find that we're getting large surges of cold water every time pump cycles off. The hot water heater is not adjustable. Any suggestions as to what might be causing this? THANKS!

There should be a valve near the water heater that isolates it for winterizing. If the valve is in the wrong position it could allow cold water to bypass the water heater. Just a thought.

If it only comes from one faucet the faucet may be bad...if you have an outside shower if the valves are open but the water is turned off at the show-head it permits the entire water system to mix.
Not my specialty, but just a couple of ideas.

Other than the items covered (bypass valve open/leaking thru, shower turned off at head, bad faucet) the other item to check would be if you have a mixing valve at outlet of water heater.

It was in winterizing mode. I feel a little silly that we had to ask, we SHOULD have figured that out on our own. MANY THANKS for answering. All is working beautifully now.

If the hot water heater was bypassed, you shouldn't have been getting any hot water at all. Your post made it seem as if you were getting hot water with surges of cold water.
I guess it doesn't matter at this point, since the problem seems to have been solved...but were you getting hot water with the hot water heater bypassed?
I just really hate being confused.
Best of luck with your "new to you" Pleasure-Way.

Well, it wasn't HOT hot, I guess it could be described as warmish. But mostly cold. So possibly we had a small amount of hot water getting through? It does seem to be working fine now, I suspected all along it was "operator error"...LOL.

Hi Lynn,
It was probably not truly bypassed but left with all three valves opened in which case water can flow direct cold or partly thru the heater. When bypassing the two valves to the heater must be closed and the bypass valve opened. In normal operation the three valves switch position. I hope that makes sense.

All I know (and want to know) about the 3 valves is that I turn all 3 in the opposite direction when winterizing and again when de-winterizing. If I try to think about what the valves are actually doing my head starts to hurt.
Just wondering, though...will the flame turn on for the hot water heater if the tank which holds the water intended to be heated is empty (i.e., has been emptied and bypassed)? I might've asked this before, but can't remember the answer. It seems like a potentially hazardous situation.

Lynne - Yes, the water heater will ignite. It does not know if there is water in the tank. Not sure how soon it will automatically shut off as air is easier to heat than water.
