Washington, DC Fire System Testing
The District is one of the most standpipe-dense jurisdictions we work in: height-limited but wall-to-wall mid- and high-rise construction, much of it with manual or combination standpipe systems that require truck pumping to test properly. We perform 5-year flow tests, hydrostatic tests, and hydrant flow tests under the DC Construction Codes and NFPA 25, and we coordinate hydrant permits with DC Water in advance. Coverage includes Downtown & Penn Quarter, NoMa & Union Market, Navy Yard & Capitol Riverfront, Dupont & Logan Circle, Foggy Bottom & West End, and more. DC Construction Codes (IBC/IFC-based) enforced by DC Fire & EMS Fire Prevention Division and DOB.
