Receive a compliance notice from Glendale Water & Power (GWP)? Keeping your water supply safe and maintaining legal municipal compliance requires certified annual backflow preventer testing. We provide fast, accurate, and fully certified backflow prevention assembly testing, maintenance, and repair services throughout Glendale, CA, and all surrounding communities within a 10-mile radius.
Our licensed testers ensure your property meets all local cross-connection control standards quickly, keeping your water flowing safely without interruption.
Complete GWP Cross-Connection Control Compliance
The City of Glendale enforces strict regulations to protect the public drinking water system from hazardous cross-connections. Under Chapter 13.32 of the Glendale Municipal Code, commercial facilities, multi-family residential complexes, and specific dedicated irrigation or fire lines must undergo testing by a certified specialist every single year.
We specialize in handling the entire GWP compliance process for you. When you book your inspection with us, we will:
- Arrive on schedule with calibrated testing gauges.
- Perform the testing procedure with minimal water disruption (usually 20 to 45 minutes).
- Complete all official city paperwork with accurate device serial numbers.
- Submit the formal Backflow Assembly Test Report directly to Glendale Water & Power on your behalf.
Our Core Backflow Prevention Services
We test, certify, and service all types of mechanical backflow prevention assemblies to protect domestic plumbing, commercial spaces, and municipal infrastructure.
Commercial Backflow Inspection
We provide comprehensive testing for property managers, retail centers, warehouses, and office buildings across the Glendale Tri-Cities area. We keep your business fully compliant and protect you from costly municipal code violations or water service shutoffs.
Irrigation & Lawn Sprinkler Backflow Testing
Lawn sprinkler systems carry high risks of siphoning fertilizers, pesticides, and stagnant soil water backward into your clean drinking lines. We certify standard residential and commercial irrigation assemblies to keep your landscape watering setup legally secure.
Fire Sprinkler Line Certification
Fire suppression networks hold stagnant water that can quickly grow bacteria or collect pipe rust. We test high-hazard commercial fire line preventers to guarantee they shut tightly against back-pressure while keeping your property safe.
Backflow Assembly Repair & Maintenance
If your assembly fails its initial pressure test, you do not need to scramble to find another contractor. Our service trucks are stocked with common factory replacement seals, springs, and rubber gaskets. We can diagnose the failure point and perform same-day repairs to get your device certified immediately.
