If you have a bypass kit installed, there will be a pipe on the back of the hot water tank between the cold input and the hot output line. There are several ways the bypass is done, with one three way valve in the cold line and a check valve between the tee and the tank hot output, two three way valves connecting the bypass pipe, or three valves and tees (the bypass pipe is connected by tees, and there is a valve in between the tank outlets and the tees and one it the bypass line.

Check the back of your tank to see if you have a bypass kit installed and tell us how it is connected and we can tell you how to set the valves.

Here's a picture of one set up:

Here is a clearer picture of a one valve set up from JohnB:

In the files area under Plumbing, I placed a file that describes all the different types of bypasses. It has been there for over a year. I suggest you download it. It will help you understand them better, and if your unit does not have a bypass, it will help you decide what kind of bypass to purchase.

Given the age of your unit, I suspect your bypass, if there is one, will be the two valve type.

If there is no bypass installed, then the one valve/one check valve bypass is very easy to install. Available at RV parts counters and online.

I remembered seeing your description and was loooking for it as an attachment to a post, never gave looking in the files section a thought.
