How do I pinpoint a leak in a slab foundation?

You may need someone who can inject high pressure air into the water line; he will have listening equipment to pick up the sound of air.

How do i pinpoint a leak in a slab foundation?
Hey joe, You call in a leak detecting service, such as Sleuth. In my area we call them when we have a slab leak. They come in and pinpoint the leak using sensitive a listening device. They then jackhammer up the slab and dig down to the leak and bag the dirt. All we have to do is drain the system down and repair the leak. Does that answer your question OK ? Cheers, Tom

Ground Penetrating Radar will work too.

GPR is a litlle bit of an overkill. Listening will work well for your home setting. In the Midwest, I work with United Leak Detection (http://www.unitedleak.com) they are in Indiana, but travel. There are others around too
