Steve,
So, where is your trailer, UK or Newport? As I understand it, the trailer is in CA, you're in UK..
If you want, I can help you next time you're in town. I live close to Newport Beach.
I wonder if the trailer has a water heaer bypass that is in the bypass mode? Or a blockage somewhere.
I think he's saying no water flow on the hot water side at all - at least that's how I read it. Think uwe is on the track. If you turned the bottom bypass to bypass but didn't open the top bypass valve - would that not shut down the flow all together. The opposite combination would do the same I think...
I had the same problem with a '68. I was going camping the next morning and was testing every thing first. I found the problem after a bit of testing. It ended up that there was a Calcum build-up( from hard water) in the HOT out pipe in the tank. Right where the Copper flair fitting attaches. I could get the tank to fire, fill, drain but not water presure. I just CAREFULLY drilled out the blockage (RELESE THE PRESHURE FIRST), flushed the tank, let it fill and spill out the open line to clean it. Put the line back on and it worked great. Hot water tanks are one of those things the allways gets over lookes at maintenence time.
Good advice so far....but there is another possibility that has not been mentioned.
If he has a check valve on the hot water outlet fitting at the tank, it may be calcified shut or simply defective. In either case, it should be replaced.....preferably with an all metal one.
I see this a lot when folks hit FL and can't get any hot water flow from their heater.......only problem is that the access to the check valve is usually almost impossible!!!!
After looking at the bypass, I would pull that check valve (if it is there)and replace it!!!
