FIRE PROTECTION WATER SUPPLY – UNDERGROUND MAINS General Water Supply Guidelines 1. Local governing authorities may require the installation of various system components. Use Factory Mutual Research Approved components. Components should be made in accordance to American Water Works Association (AWWA) or to similarly recognized standards. 2. Hydrostatically test all new yard piping at not less than 200 psi pressure for two hours or at 50 psi over the maximum static pressure when the maximum static pressure is above 150 psi. If a booster pump is present, consider the pump shut- off (churn) pressure in determining the maximum static pressure. Submittals for: Water Supply, Underground Mains, Associated Appurtenances Submittals for water supply piping installations should, at minimum, include the following items: 1. Complete set of manufacturer’s specification sheets for all components. 2. Detailed drawings indicating the location (relative to proposed or existing
buildings), depth, and sizing of all system components. 3. Sizing for thrust blocks or other pipe restraint devices FIRE PUMP/BOOSTER PUMP INSTALLATIONS General Fire Pump/Booster Pump Guidelines
1. The fire pump/booster pump and all associated, applicable components should be FM Approved. 2. Where the supply for a fire booster pump takes suction from a public main, the pump should not draw the public supply below 20 psi when operating at 150% rated capacity.
