Concrete scanning for leaks

hr

would probably be an infared camera. Check around to see if utilities or fire departments inn your area have one. it sees hot spots quickly and accuratly. Maybe check the flir website for dealers or owners inn your area.

I have used leakbusters on several ocassions, www.leakbusters.com A bit expensive but they located multiple leaks within a few inches on both jobs i used them for. They generally have the latest detector "stuff" and know how to use it!

You could spend hours, or days borrowing listening devices, or helium sets and still get goose eggs. It might pay to sourse it out.

Scanning concrete for leaks

Is there anybody located in southern Wisconsin that could scan concrete through carpet to find a leak. A friend of mine has about a 20 year old in-floor copper radiant system that will not hold pressure. When filling, the auto fill valve will not do the job unless it is switched to fast fill, then loses pressure (water) after 2 days. Sounds kind of screwy, but true. There is no sign of wet carpet, or any smell indicating water leakage. Thanks in advance.

That leak will kill the system in no time.....

Try using a staphascope (excuse spelling) to locate leak.

Do you mean a stethascope like a doctor uses to listen to your heart?? This could take a long time. How would you be able to tell the sound of circulation from a leak? My guess is somebody shot a nail into the pipe when framing basement walls. God forbid they use metal stud track with 3/4" mushroom anchors. Thanks...

try this from an old friend of mine....

....he once told me that he does this by filling the system with warm instead of cold water and an infra-red thermometer gun. The area where a leak would be shouldbe noticd with the infra-red gun. At least where the leak is being collected or filtered through. This should get you close enough to a leak.

This is just one option and to be honest, I have not tried it myself. But this fellow who told me, has been a great inspriration and mentor to me for years.

Hope this helps.

thermal imaging cameras

Thats the way I would go . They are very temperature sensative. You can touch a wall with your hand for just a few seconds and see your hand print through the camera. Most all fire departments have these cameras now. You may have to come up with a creative story to get them to come out. Make sure you heat up the floor before you call them out.

Yep

I would try to hear the running water first...Would be the cheapest and easyest way. A bucket or glass turned over may pick up sound.......No luck then move on to heat or the big guns, what ever works, I agree.

...no matter how you end up doing it, it would be very nice of you if you updated us on what you did and how you were successful.

Thanks in advance,

Low Tech

I agree infra red camera's are great if you can find someone that has one, but an easy low tech thing you can try has worked for me several times. Just lay down clear plastic sheat over the whole floor or suspected areas with the system running, the area with the leak will begin to show condensation in no time...
