Any leaks or reduction in test pressure necessitates a repair The Such a system may have a high (false) static pressure (i.e., non-flowing) caused by trapped pressure surges. This battery-powered pump delivers up to 250 PSI & 2.2 GPM with lightweight, corrosion resistant brass piping for hydrostatic testing, small-scale water transfers, and vent-line filling. During the testing period, an inspector examines the piping, fittings, and all appurtenances for visible leakage while periodically monitoring the gauge for a significant loss of pressure, which should ideally stay within ±5 of the target psi at the lowest elevation. two hours, or at 50 psi pressure in excess of the maximum static pressure when the maximum required static. Dry standpipes are only filled with water when an action is taken, and they include manual dry standpipes, which require a fire department pumper to supply water through a Fire Department Connection; semi-automatic dry standpipes, which can provide pressurized water after activating an onsite fire pump or control device; and automatic dry standpipes, from which a ready supply of pressurized water can be accessed. This may indicate a leaky pipe. Commercial sprinkler systems require a pressure of at least 200 psi for acceptance testing at installation and large modifications to the system, whereas residential NFPA 13D sprinkler systems only require hydrostatically testing the system at its normal operating pressure (for systems without a fire department pumper connection).
