Backflow Testing Glendale CA - Protect Your Water Supply
Keep contaminated water out of your clean supply lines with professional backflow testing.
Testing Required
When You Need Backflow Testing in Glendale
Glendale Water & Power requires annual backflow testing for all irrigation systems and commercial properties. Your backflow preventer stops dirty water from flowing backward into clean drinking water lines. When these devices fail, contaminated water can enter your home’s water supply. We’ve seen failed preventers allow fertilizer runoff and pool chemicals to mix with drinking water. The city sends violation notices if you skip testing. Plus, broken devices put your family’s health at risk.[1]

Common Questions
Backflow Testing Questions
Here's what Glendale property owners ask about backflow testing.
How much does backflow testing cost?
Most residential tests cost $75-$125 depending on device type. Commercial properties with multiple devices cost $150-$300 total. We include city reporting and paperwork in all prices. Failed devices need repair first which adds to the cost.
How long does testing take?
Simple residential devices take 15-20 minutes to test completely. Commercial properties with multiple devices take 30-60 minutes total. We schedule enough time so you’re never rushed. Most appointments finish faster than expected.
Can I test my own backflow device?
No, California requires certified testers for all backflow devices. Only licensed professionals can file reports with the city. DIY testing won’t satisfy Glendale’s requirements. You’ll still get violation notices without proper certification.
How often do devices need testing?
Glendale requires annual testing for all backflow preventers. Some commercial properties need testing twice per year. The city sends notices when testing is due. Don’t wait – late testing brings fines and possible water shutoff.
What happens if my device fails?
Failed devices need repair or replacement before passing certification. We fix most problems the same day with parts on our truck. Complex repairs might take a day or two. You can’t use the water connection until the device passes testing.
What are signs of backflow problems?
Discolored water, strange tastes, or chemical smells can mean backflow contamination. Water pressure drops when using irrigation systems also signal problems. But most device failures show no obvious signs. That’s why annual testing is required.
Do I need testing for my pool?
Yes, pool fill lines and chemical feeders require backflow protection in Glendale. These devices need annual testing like irrigation systems. Pool equipment creates high contamination risk if backflow occurs. We test all pool-related devices during one visit.
