Re: Corrosion Issues at Jail

Steve, Two suggestions: - Could it be that the drops are filled with water (due to flushing) and the branches are dry (due to draining or otherwaise)? - Could it be that the fittings on top of the drops are warmer than other fittings in the system (due to rising moist air from the room below)?

Are we talking about XL? I would guess that the crew that performed the final cutbacks threaded the pipe too shallow. If the space above ceiling is plenum space, the leaks may never show themselves below ceiling. I would be interested to see a fitting cut in half in order to find out whether
