Hi John too funny I was talking to a guy that works for true green. They use the 5 grand version of the thermal imaging machine. I was asking him about locating slab leaks. He said he can use the product for hot water leaks and cold will not show up. What you would have to do is hook up a hose and back feed the hot into the cold water pipe to locate with that machine.
