water heater bypass

We have a 1970 Sovereign. I need a bypass on the heater so we can winterize it each fall. Were they equipped with a bypass? All I can see from the outside is the drain plug, lighting area, etc. Where would I look for a bypass? The water heater on the inside takes up part of the white linen storage cabinet that is in the bathroom.

I don't believe that any of the 70's trailers had bypass valves on the water heaters as they came from the factory. If one has been installed by a previous owner, you will find a couple of valves on the back side and a pipe between the top (hot) water outlet and the bottom (cold) water inlet. If there is nothing but a hot and cold pipe to the heater then you don't have one. They are not too difficult to add, but that depends on your access to the rear of the heater and how corroded the pipes may be to the tank.
