Is there a valve either on the incoming or out going side of the water heater?

Is this a domestic hot water line. Or a radiant slab heating line?

not much info. Shut off the water to the house all togother. Now shut off the power or gas Off on the water heater . Now run a new line over head to the other hot outlet's .Now this is going to be a hard thing to do. Now you are going to have to run to each hot water fixture. Or the water will go back to the open line where you cut it off at the hot side of the heater. That is a lot of work. But look's like that is your answare ? I didn't read and other post's . May be some other post's

First turn the little knob from run to pilot (gas water heater). Or shut off the breaker (electric).

There should be a valve right above the heater that will kill the cold water into the heater.

Open hot faucets upstairs and drain two or three gallons from the valve at the bottom of the heater tank. This should get most of the water out of the pipes so it doesn't get all over you when you cut a pipe to make new connections and repairs.

Have water flowing from hot faucets before turning the heater back on.

My uncle had this problem and he had a plumber come in and string a new hot pipe from the water heater overhead to the kitchen etc. The plumber did have to drill through a brick wall. My uncle didn't realize there was a leak until he found that his electric bill was $400. higher one month (it was an electric water heater).

Running the plumbing through the attic willonly work in warmer climates or in 2 story houses. You may need to hire a leak detection company to find the leak exactly. Then you will know your options to repair it.

Do it yourself Leak Deteciton is why companies like our exist. I can tell do it yourself on either re-route or a spot slab repair, but you have to know where the leak is coming from first. In the Midwest (through Google) I already advertise on this page. I was trying to help out, and suggest advice for the gentleman to have a complete enough information set to do his own work. With out it,(and based on the posts so far) I think there is a good chance he will spend too much or not do the job correctly. My post is a best suggestion for him to work towards fixing his own problem without making the mistake of making a hole and not finding the leak or re-routing and not needing to. Thanks,
