A Dry Pipe Sprinkler System

A dry pipe sprinkler system is a system with automatic sprinkler heads attached to a piping system containing air or nitrogen under pressure.

The release of this pressure (as from the opening of a sprinkler) permits the water pressure to open a valve known as a dry pipe valve and the water then flows into the piping system and out of the open sprinkler head.

Dry pipe sprinkler systems are installed in areas where wet pipe systems may be inappropriate, such as areas where freezing temperatures might be expected.

Dry pipe fire sprinkler systems are often installed incorrectly where the piping is not properly pitched, which results in trapped water. Having trained and qualified professionals to service your system is critical as we can identify your low points and drain trapped water annually, or more often if needed, before freezing temperatures in winter ruin the system piping. We provide winterization preparation services, draining trapped water and even reinstalling piping to proper pitch to best prevent our customers from needing unnecessary repairs.

Our sprinkler fitters complete a five-year formal union apprenticeship program before working alone as a foreman.

During this training, they are exposed to extensive hands-on and classroom setting training, including specifically resetting a myriad of new and old dry valves. NFPA 25 requires that your dry valve be internally reset, cleaned and maintained at least annually. Our trained professionals will take the extra time to leave your system clean and in proper working condition.
