water heater hot not hot at faucets

Nothing weird about it at all. The same thing can happen in a residence when a shower is equipped with a handheld shower head with a separate shutoff that's left off with the valves on. It may take longer for the problem to show up in a residence, but that's just a function of the longer pipe runs. It can be fixed with a set of check valves at the inside and outside faucets, but it's probably not cost effective for the few times the issue occurs.

It does sound weird. Sometimes I wonder if RV mfgs should really tone down on the "save weight" issues and simply not skimp on the plumbing. We need good plumbing!

YEP......anytime fixtures are left valved in (not turning off using the hot/cold knobs) the fixture itself becomes a 'mixing chamber' which allows the hot/cold to mix diluting the hot making LUKE WARM water

Same thing happens after de-winterizing'........bypass on WH gets left open or not fully closed. Again LUKE WARM water due to hot/cold mixing


Glad to hear Fleetwood Customer Service was aware and clued you in.
Most just don't have a clue and diagnosis issue as a problem with the WH itself like you found when calling Atwood :S

BTW bad check valve results in limited flow on hot water side or NO hot water flow.......not luke warm water
Same with element..they heat or don't

Happens all the time....folks leave their outside shower valves on but have the hand held sprayer off...thus no hot water inside at faucets.
