Ahh..lol. yes, cold water heater. Anywho... I checked behind the heater, which took forever looking in every nook and cranie. There is no shut off valve. Oh well. I was hoping to be able to work on it for a few days without having to shut off the water to the whole plumbing. Thanks for the help.

how about shutting down the water to the camper, open a faucet to drain off pressure, remove the water heater, and install a shutoff valves on the inlet and outlet pipes .... by doing so you can use the camper while working on the water heater

I doubt a heater that old would have a valve. Cost you know. Old plumbers joke. "why do you want to heat hot water"

Thanks. I'll check it out.

@Tim Pusher...lol

Why does it have a "hot water heater"? :)

back of the heater if there is on that old of trailer may not have one

Shut off valves for water heaters are located on the backside of water heater tank (inside RV).

MFG. use different ways......
Some use just 1 valve (3 way valve) on cold inlet with a check valve in hot outlet


Some use 2 valves.......one on cold inlet, a bypass valve (connects cold/hot lines) and a check valve in hot outlet


Some use 2 valves (3 way valves) on cold inlet and hot outlet

Now you just need to find the backside of your WH tank..and which valve system you have :B
