Standpipe Systems

Installation, inspection, testing, and repair of standpipe and hose systems for multi-story and large-footprint buildings across the Central Valley.

What Is a Standpipe System?

A standpipe system is a network of vertical piping installed inside a building that provides fire hose connections at every floor. During a fire, firefighters connect their hoses directly to these outlets instead of stretching lines from the engine on the street — saving critical minutes in multi-story buildings where time and vertical distance are the biggest obstacles to an effective response.

When Is a Standpipe Required?

Under the California Building Code and NFPA 14, standpipe systems are generally required in buildings that exceed a certain height or floor area. Most buildings over three stories, high-rises, large assembly spaces, underground structures, covered malls, and stages require standpipe systems. Your local AHJ may have additional requirements depending on the occupancy type and building configuration. If you’re unsure whether your building needs one, we can review your plans and let you know.

Types of Standpipe Systems

There are three classes of standpipe systems. Class I systems provide 2½-inch hose connections for fire department use and are the most common in commercial and high-rise buildings. Class II systems provide 1½-inch hose connections intended for building occupant use. Class III systems provide both 2½-inch and 1½-inch connections, combining fire department and occupant capabilities in a single system. We install and service all three classes.

Installation

We install complete standpipe systems including vertical risers, floor control valves, hose connections, fire department connections (FDC), roof manifolds, and all associated piping and signage. Standpipe installations require careful coordination with the building’s structural and mechanical systems — especially in high-rise construction where pipe routing, seismic bracing, and pressure zone management are critical. We work closely with general contractors, engineers, and the AHJ throughout the process.

Testing & Inspection

NFPA 25 requires regular inspection and testing of standpipe systems to ensure they’ll perform when needed. This includes visual inspection of piping, connections, and signage; flow tests to verify adequate pressure at the most remote hose connection; hydrostatic pressure tests at required intervals; and functional testing of all valves, gauges, and pressure-regulating devices. We provide certified reports documenting all test results and any deficiencies found.

Repair & Maintenance

Leaking connections, corroded piping, damaged hose valves, malfunctioning pressure-reducing valves, and missing or illegible signage — we handle all standpipe repairs to keep your system fully operational and code-compliant. If your system has failed an inspection or received a deficiency notice, we can assess the issues and complete the corrective work to get you back into compliance.
