Fire service lines for commercial buildings

A building with automatic sprinklers usually needs its own fire service line: a larger pipe from the water main that feeds the sprinkler system, separate from the domestic service that supplies sinks and restrooms. Its design, its materials and its testing are governed by the fire code, the water utility and the fire protection engineer.

A fire service project typically covers:

The tap

A connection to the main and a valve, arranged with the water utility, which may perform or witness the tap.

The line

Pipe of the size and material the design calls for, laid with restraint at bends and fittings so it stays in place under pressure.

The entry

Where the line rises into the building to meet the sprinkler contractor's work, including backflow protection as the utility requires.

Testing

Pressure testing and flushing, witnessed as the fire authority and the utility require, before the system is put into service.

An existing building that is adding sprinklers, or a fire line that has failed, is handled the same way. We also handle domestic water, lateral, storm and conduit work for homeowners and small businesses in West Des Moines.

Iowa One Call before excavation

Under Iowa Code chapter 480, excavators notify Iowa One Call before digging. Iowa Code section 480.4 requires 48 hours of notice, counted from 6:00 a.m. on the next business day without weekends or holidays, and a ticket stays valid for 25 calendar days. Include the exact address, as the city spans more than one county.
