Once all the air is released, the valves between the existing distribution system and the pipe to be tested are closed. Thus, a loss of a little over 5 psi at ground level might indicate a small leak, whereas if the 200-psi test pressure drops to the city water pressure of about 50-60 psi, it indicates that there is a catastrophic failure in the system. Sprinkler Testing, I read your blog on daily basis. 4.3 Larger mains of higher capacity will require the simultaneous testing of several hydrants. Automatic versions of both types of standpipe are pressurized (wet with water, dry with air), enabling anyone to simply turn a valve to access water, which is often already connected to an onsite hose within a pinrack unit. 1 Pressure testing involves applying stored energy to an assembly of parts, in order to verify its strength, its integrity and/or its functionality. The test pressure applied to the water main for the leakage test shall be maintained as constant as possible for not less than two (2) hours. NFPA 25 is unclear about what constitutes an acceptable drop in pressure, noting “Minimum leakage existing only under test pressure is not cause for repair.” That said, the separate NFPA 13 guidance on hydrostatically testing underground pipes in fire sprinkler systems may provide some insight: 10.10.2.2.1* All piping and attached appurtenances subjected to system working pressure shall be hydrostatically tested at gauge pressure of 200 psi (13.8 bar) or 50 psi (3.4 bar) in excess of the system working pressure, whichever is greater, and shall maintain that pressure at gauge pressure of ±5 psi (0.34 bar) for 2 hours.
