Sent from Samsung Mobile -------- Original message -------- Subject: RE: Testing for Air Leaks in Dry Fire Sprinkler System From: Plumbco <[email protected]> To: [email protected] CC: Years ago we had a customer, on his own, use the refrigerant gas method, his problem was that he had ammonia systems for refrigeration. After the ammonia ate the brass seats in the sprinkler heads and the rubber gaskets in the grooved couplings, the pinholes in the pipe seemed pretty insignificant. Depending on the weather and occupancy we prefer to fill them up and look for the wet spots.
