Hi all, We have a mystery pipe here which we really need to locate. It is an unused 2" electric svs pipe (grey) that goes from our panel inside the house to "somewhere" outside. It goes under slab and is at least 50 feet long, as we put a snake down it and ran out of snake! We assume it exits somewhere logical for a planned extension, but short of digging down 2ft deep all the way round the house there appears to be no way to locate it. The builder is long gone..weve tried tapping with a mallet on the slab and listening, tapping on the pipe inside.. were at a loss..
Any tricks here? We could really use this if it is found to be accessible..
Any help appreciated.
