Trying to locate leak in radiant loop

Mike Lampkin_2

One of the radiant loops was damaged during the concrete
pour in a 4 inch slab on grade. There was a good air test
on the loops before the pour, but at completion of the
pour, it was noted that the pressure had dropped. The
faulty loop has been found, but I haven't been able to
locate where the actual leak is occuring under the slab.
I'm looking for different ideas fot trying to find the
leak. I have tried wetting the floor with soap and water
to see if any air bubbles were coming to the top of the
slab, but nothing showed up. The slab has only been poured
for two days. Thanks very much for your help.

filling loop with water and increase pressure with air, then go looking for the wet spot. may take a little while. marc.

Floor leak .....

You have it pumped up with air ........what about a "stethoscope"? If filled with hot water , use a infered thermometer and look for a flume....

What Ed said...

Thermal energy has proven itself to be one of the best leak locators I've used over the eyars. I find it with heat and verify it with ultrasonic leak detection equipment prior to operating...

If all else fails, Google Leak Busters or AMerican Leak Detection and see if theres someone in your neighborhood. THey have ALL the coolest equipment.

Let us know what you find. PRobably a concrete rake tooth hole...
