Question No hot water !!!!!

Yesterday I had a problem that completely baffled me. This 2008 Bounder 37D is new to us, so I'm still figuring things out. This is our second outing in this MH. Went to use some hot water and found it was barely warm. Thought "water heater", but it was full on HOT water. Came back inside and turned on the kitchen water and ran awhile, still warm. Turned on the bathroom water and the kitchen water got HOT.

Called the dealer we purchased from and talked to the service manager. He said the bi pass valve must have gotten turned. I checked but it was in the normal position. I turned it off and back on and now I have HOT water again at all locations.

While it is fixed, I can't figure out what was wrong in the first place. Don't want to go through this on a regular so I'd like to know what caused the problem and why moving the bi pass fixed it ?

Bill

If the service manager was right about the problem being the bypass valve, maybe there was some type of debris partially blocking it, which was dislodged when you turned it.

yep probably crap inside the valve. I had a customer come last week with no hot water. After checking the basics the thought was mixing valve at the heater, but then I thought for half a second and went and checked the faucets and lo and behold the outside faucet shower cold had been left on - thus acting as a mixing valve. Shut it off and hot water again at all locations....

Nuts......On occasion, this problem is caused by the outdoor shower. If it's turned on at the knobs, but turned off at the head, it will cause hot water flow issues. Make sure it's turned off at the knobs.

Yup, I'm in the habit of using the outside shower to bleed water pressure from Hot and Cold before I disconnect the water hose when de-camping, since it is right next to the hose connection. One time I left the knobs turned on, and couldn't figure out for a day why the water in the coach was luke warm at best.
Ooops !

If you do not have an incoming water filter....those are the types of reasons to have one. A simple one like this will catch the sediments before it reaches valves and faucets.

Thanks

Don,

Thanks, I believe you have hit the problem right on the Hot Water. I had been using the outside shower that day, as I was doing a bucket wash on the MH. I don't remember messing with it during my trouble shooting, but I'll bet I did and shut it off !!!

Thanks
Bill

#1 cause of the symptoms you mentioned is that outside shower #2 is the inside shower.

One more thing not many talk about. There is a back flow valve at the HWT THAT may stick. Bug that doesn't tell me why hot in bath and not in kitchen. Still looking for thelogic it this happening.
