The only thing I can see with that shower head is if the hot is turned on and the knob at the head is shut off to block water at the head, then the shower head is acting as a mixing valve. It is mixing hot and cold. Don't know how it could be happening on city hook up only. Never fixed anything in that area...

Can you explain why? I KNOW this worked in my case, but not sure how the outside shower faucets have this effect.

Just wondering if it is as simple as the pilot light for the heater went out, that is the first thing I would think of....Not being a mechanic or anything,

no, I had hot water when using the water pump, but no hot water when hooked to city water.

Other posters have said that the outside shower might be the culprit. If the faucets on the outside shower are turned on and the valve at the shower head is turned off (to close the flow), then hot and cold water are mixed and so your hot water becomes lukewarm. The faucets act as a mixing valve. Did you check to see if your outside shower faucets are both closed?

the exterior valves were both open, but the shower head sprayer was closed, thus mixing hot and cold. After closing both valves, I was able to get hot water indoors thru both the city water and 12v pump.

no hot water on city

However, being on city water does not matter because the pump is supplying the same system the same way, so that is not it.
I just bought a 08 Cardinal M-33TBH (Forest River); the first time I hooked it to city water a pipe just flowed out near the water pump & leaked all over the board etc.
After drying it out & 2 very nice neighbor campers sealed the pipe I made a few discoveries about the camper.
There was no hot water flowing no matter what direction I turned the valve for winterizing!!!
Then I discovered the they had removed the outside shower faucet & replacedthe bathroom shower with them!

After reading this article, I realized there is a relationship involved...
The hose that was flowing quite well ended in a tee under the bathroom shower near the pump & also the converter (inverter?). I was very lucky no one got shocked when it got so wet in that area! I should have had someone outside while we were working on the valve under the sink!
If anyone has any ideas, I would very much welcome the advice!
This forum has been so helpful; my thanks to all!!
Cheers,
Paul
