Your Complete Sprinkler System Partner

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.

  • Hydraulic calculations and permit drawings included
  • CSFM-licensed contractors and NICET-certified technicians
  • Coordination with local AHJ (Authority Having Jurisdiction)
  • Annual, 5-year, and ITM (Inspection, Testing & Maintenance) programs
  • Retrofit and tenant improvement sprinkler work
  • Emergency response available statewide

Why Sprinklers Matter

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.

Fire Sprinkler Systems We Design & Install

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.

Wet Pipe Sprinkler Systems

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.

Office Buildings Retail Hotels Most Common

Dry Pipe Sprinkler Systems

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.

Parking Garages Cold Storage Warehouses Unheated Spaces

Pre-Action Sprinkler Systems

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.

Data Centers Archives Museums Libraries

Deluge Sprinkler Systems

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.

Aircraft Hangars Chemical Plants High-Hazard Industrial

Sprinkler Services from Design to Repair

We cover the full sprinkler system lifecycle — so you never have to juggle multiple contractors for the same system.

System Design & Hydraulic Calculations

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.

  • Hydraulic design per NFPA 13
  • CAD permit drawings
  • AHJ coordination & plan check support

New System Installation

Full installation for new construction and major renovations — from underground mains and risers through branch lines, heads, and final trim and test.

  • All system types (wet, dry, pre-action, deluge)
  • New construction & ground-up builds
  • Coordination with GC and other trades

NFPA 25 Inspection, Testing & Maintenance

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.

  • Annual, 3-year, and 5-year NFPA 25 programs
  • Flow tests, trip tests, obstruction investigations
  • Certificate of inspection provided

Repair & Emergency Service

Broken heads, corroded pipe, valve failures — our technicians respond fast to restore system integrity and get you back into compliance.

  • Head replacements & pipe repairs
  • Valve and trim replacements
  • Emergency response statewide

Retrofit & Tenant Improvements

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.

  • TI sprinkler relocations & additions
  • Coverage extensions for new occupancies
  • Head change-outs for temperature, finish, or coverage changes

Backflow Prevention & 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.

  • Annual backflow testing & certification
  • Backflow assembly repair & replacement
  • Water supply analysis for system upgrades

We Know the Codes That Govern Your System

California sprinkler systems are governed by overlapping federal standards, state regulations, and local amendments. We keep up so you don't have to.

NFPA 13

Standard for the Installation of Sprinkler Systems

The primary national standard governing design, installation, and component requirements for all commercial fire sprinkler systems. All Delta installations are NFPA 13 compliant.

NFPA 13R

Sprinklers in Residential Occupancies Up to 4 Stories

Simplified installation standard for residential buildings up to four stories. Commonly required for multifamily apartment buildings and hotels in California.

NFPA 25

Standard for Inspection, Testing & Maintenance

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.

Title 19

California Code of Regulations — Fire Safety

California's state-level fire safety regulations adopt and amend national standards. All Delta work is performed by contractors licensed under Title 19 requirements.

Why Single-Vendor Maintenance Matters

  • Accountability: One contractor owns the entire system — no finger-pointing between installers and inspectors.
  • System history: We keep complete records from installation through every inspection — invaluable for permit renewals, insurance, and AHJ audits.
  • Faster response: When something goes wrong, the team that installed your system can diagnose it faster than a contractor seeing it for the first time.
  • Lower total cost: Bundled inspection, maintenance, and repair contracts typically reduce per-service costs compared to piecemeal vendor relationships.
  • Compliance continuity: Code interpretations and AHJ expectations shift. A long-term partner stays current and proactively flags upcoming requirements before your next inspection.

Everything Under One Roof

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.

Unified Compliance Calendar

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.

Emergency Response Across California

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.

Cross-System Expertise

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.
