How to find pipes under concrete floor.

The first indicator is the presence of water or damp spots on your floor. My problem is letting them drill without hitting the 1 2 inch pex in the cement. Feel your floor for warm spots. This is a snake that is put into the your house sewer line and on the end of that snake is a signal that s is bounced to the hand held locater that it finds exactly where the sewer line is and tells you the depth of it.

I do have pictures of the floor before it was poured but not in enough detail to be certain to not hit a tube. If the spot stays hot for over 24 hours it might be over a broken hot water pipe. If you find one mark the area with masking tape. It s the perfect way to locate a sewer line as long as there is a clean out or a drain to get into.

Also depending on the way it s routed i might still opt to run the new drain line along the ceiling depending on how much damage i would need to do to the finished floors in the basement. Cut a channel where the pipe is with a grinder then get an sds breaker and take out all the screed if its buried in concrete then highly unlikely you will be able to get to it if it is old and copper then just put a new pipe in complete length with no joins under the ground perhaps in channel under the floor or inside a duct. These will be particularly pronounced on tile or wood floors. Luckily there are several signs that indicate a leaking pipe under your slab.

Leaking hot water lines can also create warm spots on your floor.
