i'm curious what different people use to detect a slow leaking water main that will not expose itself.
this is a pretty interesting subject. i have worked on project with up to 200 miles of pipeline and have seen some really slow leakers. the worst one was a pvc pipe that had rubbed on the delivery trailer and the water was "misting" out of the rub marks. this was probably a half a cup an minute leak but it was enough to fail a pressure test. to find it we cut the line in half and tested. then cut it in half again. then again. and again. and again.
most of the time a person can drag your feet long enough and a leak will surface. i have not seen anything really great that can help you detect one in pvc pipe. i have tried listening devices but had little luck
i would to see this thread continue to grow.
