Can anyone help me with ways and hints to locate a broken pipe from freeze damage in a wall? There is no attic space and I was on the road while the freeze occurred and did not discover the pipe broke until 3-4 weeks after the damage. There is an area of water damage (peeling paint, damaged sheetrock) that goes most of the length of the wall. I considered obtaining a stethoscope and turning the water on to locate/pinpoint where I should be cutting out the possible area. The little converted garage apartment has been recently updated in its interior so I would like to minimize any destruction/construction in the repair? Thank you.
