The most common test involves measuring the flow of water flowing out of a municipal fire hydrant (measured in gallons per minute) while recording how much the water pressure has dropped (from no water flow to test flow). If the leak is not visible, it could mean that it is occurring in hard-to-access areas, such as underground piping.

When a sprinkler activates this water is immediately discharged onto the fire. Open a valve (such as the For fire protection systems, the piping is pressurized to 200 psi (13.8 bar) for a period of 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. where high pressure exists, the standard requires that the test pressure be 50 Hydrostatic testing of Piping Designed for External Pressure. system, for open valves, or for leaks in the test apparatus. To learn about the cookies we use and information about your preferences The pressures in piping at higher elevations shall be permitted to be less than 200 psi (13.8 bar) when accounting for elevation losses. Instead, sprinklers are only hydrostatically tested when they are first installed or whenever the system is modified. 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. The leakage test shall be held concurrently with the pressure test. commissioning agent or authority having jurisdiction that the 2-hour test Such a system may have a high (false) static pressure (i.e., non-flowing) caused by trapped pressure surges. After the test, open the drain valve pressure has stabilized, disconnect the power to the test pump and notify the Essentially, the entire system must be tested at (at least) 200 psi for two hours upon installation. This false high pressure should be adjusted to reflect the actual supply side pressure. Fire Protection Underground Piping •Testing of underground piping •Pressure test to 200 psi OR 50 psi over static pressure exceeding 150 psi •Leave joints exposed •Some leakage allowed •Flush until clean @ 10 ft/sec, system demand plus hose, OR full flow of supply •Require a UG Contractors Materials & Test … Foundation shall be sufficiently substantial to form a permanent and rigid support for the base plate (6.4.4).
