Wet pipe, dry pipe, pre-action, and deluge systems designed, installed, inspected, and maintained by licensed California contractors. Serving commercial and industrial properties statewide since 1990.
Automatic fire sprinkler systems are the most effective tool for controlling a fire in its early stages — buying critical time for evacuation and dramatically reducing property damage. Delta Fire Equipment handles every phase of the sprinkler lifecycle, from hydraulic design and permit coordination through installation, annual NFPA 25 inspections, and emergency repair.
We work with property managers, general contractors, building owners, and facility engineers across California to keep systems code-compliant, operationally ready, and properly documented year-round.
Sprinkler systems reduce the risk of death in a commercial building fire by over 80% and reduce property loss by over 70%. Yet many California properties operate with aging, non-compliant, or un-inspected systems — creating serious liability and code violation exposure.
From light hazard offices to high-challenge cold-storage facilities, we select and install the right system type for your occupancy, climate, and risk profile.
The most common and cost-effective system type. Pipes are permanently charged with water, so any activated sprinkler head immediately discharges. Ideal for heated spaces where pipes won't freeze.
Pressurized air or nitrogen fills the pipes until a head activates — then water rushes in. Essential for unheated spaces, parking structures, and areas prone to freezing temperatures.
A two-step activation: the system must receive an alarm signal AND a head must open before water flows. Used where accidental discharge would cause severe damage — data centers, archives, museums.
All heads are open simultaneously — the entire system floods a hazard area at once when triggered by a detection system. Used for high-hazard occupancies requiring immediate, total suppression.
We cover the full sprinkler system lifecycle — so you never have to juggle multiple contractors for the same system.
We produce permit-ready hydraulic drawings and coordinate submittal with your local fire department or AHJ — handling the paperwork so you can focus on your project.
Full installation for new construction and major renovations — from underground mains and risers through branch lines, heads, and final trim and test.
Annual, quarterly, and 5-year ITM programs that keep your system compliant and your certificate of inspection current. We document everything for your records and the fire marshal.
Broken heads, corroded pipe, valve failures — our technicians respond fast to restore system integrity and get you back into compliance.
Remodeling, reconfiguring, or adding sprinkler coverage to an existing space? We design and install retrofit systems that integrate with your building's existing riser and water supply.
We test, certify, and repair backflow prevention assemblies on sprinkler supply lines — a common requirement for annual fire inspection sign-offs in California.
California sprinkler systems are governed by overlapping federal standards, state regulations, and local amendments. We keep up so you don't have to.
The primary national standard governing design, installation, and component requirements for all commercial fire sprinkler systems. All Delta installations are NFPA 13 compliant.
Simplified installation standard for residential buildings up to four stories. Commonly required for multifamily apartment buildings and hotels in California.
Governs the ongoing ITM requirements for all installed water-based fire protection systems. California fire inspectors cite NFPA 25 non-compliance as one of the most common violations.
California's state-level fire safety regulations adopt and amend national standards. All Delta work is performed by contractors licensed under Title 19 requirements.
Delta Fire Equipment handles fire alarms, suppression systems, extinguishers, and emergency lighting in addition to sprinklers — giving you a single point of contact for all life safety compliance.
We track all your inspection due dates across every system and notify you proactively — so you're never caught off guard before an AHJ visit or insurance renewal.
A sprinkler line breach or failed dry pipe valve is an emergency. Our field teams are dispatched statewide and respond with parts on the truck to restore your system quickly.
We understand how your sprinkler system interacts with your fire alarm, detection system, and building controls — and can troubleshoot the full stack instead of just one piece.
Whether you need a new system designed from scratch, a retrofit for a tenant improvement, or an overdue NFPA 25 inspection — call us today for a free quote.
