Backflow Testing & Prevention
Keep Your Water Supply Protected
Backflow testing keeps contaminated water from siphoning back into your clean water supply, and it’s a service we perform regularly for homes and businesses throughout La Crescenta, La Cañada Flintridge, Montrose, Glendale, and Burbank. Backflow prevention devices are required by many municipalities for irrigation systems, commercial properties, and certain residential setups, and we make sure yours passes inspection and keeps working when you need it.
Our technicians are certified backflow testers, licensed (California C-36 #1027398), and familiar with the specific requirements of local water providers in this area. We handle the testing, the paperwork, and the filing with your water district so you don’t have to track deadlines or forms yourself — we’ll even remind you when your next annual test is due.
Our Backflow Services Include:
Certified Annual Backflow Testing: We perform state-certified backflow testing to keep your device compliant with local codes, and file the required paperwork with your water provider.
Backflow Device Installation & Repair: Whether you need a new backflow preventer installed or an existing one repaired, our licensed technicians handle it correctly the first time.
Cross-Contamination Protection: We help protect your potable water supply from contamination caused by irrigation systems, pools, and other cross-connection risks.
Commercial & Irrigation System Testing: Restaurants, HOAs, and properties with landscape irrigation often need multiple devices tested — we can handle the whole property in one visit.
Failed Test Repairs: If your device fails inspection, we diagnose and repair it promptly so you stay compliant without a lapse in service.
Staying current on backflow testing protects your property from fines and, more importantly, keeps your water genuinely safe. You can verify our license anytime through the California Contractors State License Board. If your backflow test is due or you need a new device installed, call us at (818) 790-7270 or request service online.

Backflow Testing, Repair & Prevention
A backflow prevention device stops water in a building’s plumbing from reversing direction and re-entering the potable supply. Backflow can occur when supply pressure drops — during a main break or heavy draw — or when downstream pressure exceeds supply pressure. The device is a safeguard on drinking water, which is why it is tested rather than simply installed and forgotten.
What we do
- Testing of existing backflow prevention assemblies
- Repair and rebuild of failed or leaking devices
- Replacement where a device is beyond repair
- Installation of new assemblies
- Documentation of test results for submission where required
Where these devices are found
Commonly on irrigation systems, fire suppression connections, boiler and mechanical make-up water, commercial kitchen equipment, and building supply connections in multi-unit and commercial properties. Properties with irrigation or any auxiliary water source are typical candidates.
Commercial, HOA and multifamily relevance
Backflow assemblies are most often encountered on commercial and multi-unit properties, and testing is generally a recurring obligation rather than a one-off — which makes it a natural item to keep on a schedule alongside other planned work. See preventive plumbing maintenance, HOA & property management plumbing and commercial plumbing.
Testing requirements, intervals and reporting obligations are set by your local water purveyor and vary by jurisdiction and by the type of connection. We do not advise on what your specific requirement is — check with your water provider, and we will carry out and document the testing accordingly.
Signs a device needs attention
Continuous discharge from the relief port, visible corrosion or damage, reduced pressure downstream of the assembly, or a device that has not been tested in a long time. A failing assembly can also cause pressure problems that are mistaken for a supply issue.
FAQs
How often does testing need to happen? That is set by your water purveyor, not by us — confirm the interval with them.
Can a failed device be repaired? Often yes, by rebuilding the internal components. Where it cannot, replacement is the option.
Do you provide documentation? Yes — test results are documented and provided for submission where required.
