Hello all,
We have a 1” diameter copper (ASTM B88 Type K) line embedded in mass concrete that is part of a Piezometer system that is not holding pressure in a hydro dam project.
Prior to concrete placement it was tested and held a test pr of 290psi, but post concrete placement the pressure quickly falls to 125psi, then gradually to 0.
Total length is about 30 meters, with 6 nos of 1" elbows - so we are expecting the leak somewhere around first 15 meters.
As this is embedded no way knowing where the leaks are - so looking for an expertise, suggestions or experience in dealing such situation
