  • Slab Leak Locating idea...

    I had a customer with a slab leak but water was not getting above the slab, the customer could hear running water at night which generated the call...
    I decided to try something a bit different

    I back-fed Hot water into the cold water system and used a non-contact thermometer on the concrete to narrow down the jackhammer area as this was the customers living room.

    I marked the area that mapped the warmest area in white and started demo.

    I think I'm going to do this from now on..

          This was waaaay easier then using a mic IMO and it worked really well with a $60 temp gun

            I was in a crawlspace from he!! today. But I have to say that slab repairs seem like such a b!tch.

            Way to think around things Bill. I see you got your braze on.

                Before all of today's new technology existed I was considering training a dog to do my locating for me.

                    i use my ir thermometer to routinely find the waste lines and test fixtures. i can aim the laser at the overhead piping and get a reading while running hot water. no ladder needed and i don't have to touch the pipe.


                    now pair your ir with a pipe locater and you'll be dead on. when the target area is large, such as on a hot water line, you need to know where the pipe is running and narrow down your area. also compressed air works good for noise generation.

                    a lot of my leak locations are nothing more than a good ear and compressed air, after locating the pipe path with my scout and navitrack transmitter.

                    good job, but why the sharkbite in the photo

                      Rick,
                      I used the sharkbite to cap off the line after I cut out the damaged section to verify there were no more leaks upstream and I did the same on the downstream side by back feeding water... They are just easy to put on and take off for testing.

                        Post, The linked tool is basically (a different brand) what I used...

                        I used a pencil and wrote the temperature readings on the slab in a 2" x 2" grid then I could see what direction the pipe was running once I could see where the pipe was it was just a matter of marking the hottest area and removing enough concrete to make the repair.

                          when i was in NY we had a lot of copper heat pipes in the slab and i used a stethoscope to find mine
