finding a radiant leak in concrete

Derheatmeister Member Posts: 1,514
Thermal Camera works good also i use a Audio listening devise ,or a laser scanner from the auto parts store may work,and if you believe in it the well finding technic works to:

#1: Take two pens(I used the papermate) take the case only

#2 Take two pieces of wire (Approx 18") bend a 90 angle at approx the length of the pen chase 5 1/2"

#3 stick the wire into the pen case and hold the cases in your hands approx 4 to 6 inch apart..

#4 hold the pen cases steady and try finding a body of known water i.e. a well or toilet.. You will know it when you find it: the wires will cross.

Once you "mastered" the fine art of finding a body of water
try it on your radiant leak!

Some say it's: "Hokus pocus" but it has worked for me before with in 8" at 3 feet deep

Good luck..

    finding a radiant leak in concrete

    has anyone had to find a leak in radiant tubing in 4" of concrete? (1/2" Viega hepex). I'm working on renting a thermal imaging camera, but seeing if there are any other options out there. The pressure seems to drop faster the hotter the tubing is

    Devining rod

    Heatmiester, I have a friend that does that trick to find buried field tile in farm fields. He uses a couple of pieces of bent brazing rod and swears by it!

    I actually used the brazing rods a couple weeks ago to find my daughter's sewer line in her back yard. Approached it from several different angles and came up with the same spot. Dug down 3 feet and Viola, found the sewer line. I'm a believer.

    Damp Mop

    Take a damp mop and mop the floor. You'll see the layout of the tubing as the floor dries, except where the leak is.

    For any Wallie, I'd be happy to UPS my cat to any address in the USA! She loves the warm spot at the leak! She finds it every time!
