If you’ve received a notice from Glendale Water & Power requiring your backflow prevention assembly to be tested, you’re not alone. Every year, thousands of residential and commercial property owners in Glendale must complete certified backflow testing to remain in compliance with local water regulations.
Whether you own a home, apartment building, restaurant, medical office, or commercial property, understanding the testing process can help you avoid missed deadlines and keep your property’s drinking water protected.
Why Is Backflow Testing Required in Glendale?
Backflow prevention assemblies are installed to protect the public drinking water supply from contamination.
Normally, water flows in one direction—from Glendale’s water distribution system into your property. However, if water pressure suddenly drops because of a water main break, firefighting activities, or another event, water can reverse direction. This is known as backflow.
If backflow occurs and a properly functioning backflow prevention assembly is not in place, contaminated water from irrigation systems, fire sprinkler systems, boilers, chemicals, or industrial equipment could enter the public water system.
Annual testing helps verify that your assembly is operating correctly and continues to protect the community’s drinking water.
Which Glendale Properties Need Backflow Testing?
Backflow prevention assemblies are commonly required for:
- Commercial buildings
- Restaurants and cafés
- Medical and dental offices
- Apartment complexes
- Industrial facilities
- Schools and churches
- Irrigation systems
- Fire sprinkler systems
- Multi-family residential properties
- Certain single-family homes with identified cross-connections
If your property has a required backflow assembly, Glendale Water & Power will typically notify you when your annual test is due.
What Happens During a Backflow Test?
A certified backflow tester will:
- Inspect the backflow prevention assembly
- Connect calibrated differential pressure testing equipment
- Test each internal check valve and relief valve
- Verify that the assembly meets required performance standards
- Complete the required compliance documentation
- Submit the test results electronically when required by Glendale Water & Power
Most appointments take between 20 and 45 minutes.
What If My Backflow Assembly Fails?
A failed test does not always mean the assembly must be replaced.
Many failures are caused by normal wear on internal components such as:
- Rubber seals
- Springs
- Check valves
- Relief valve components
In many cases, these parts can be repaired, allowing the assembly to pass a follow-up test.
If the assembly is no longer repairable or replacement parts are unavailable, installing a new approved backflow prevention assembly may be the best option.
