Fresno Certified Backflow Testing Specialists

Protecting your drinking water from contamination is our top priority. Our team of certified backflow testers in Fresno is equipped to handle all your testing needs. Whether you need an annual inspection or a new installation, we ensure your backflow prevention assembly is functioning correctly to prevent non-potable water from entering your clean water supply. We handle all the necessary paperwork and submit it directly to your local water authority, making the process hassle-free for you.

If your backflow preventer fails the annual test, don't worry. Our skilled plumbers can diagnose the issue and perform the necessary repairs to get it back to passing standards. We carry a wide range of parts for various makes and models to ensure a quick turnaround.

In cases where a unit is beyond repair or a new system is needed, we offer professional installation services. We install high-quality backflow prevention assemblies that meet all state and local codes, providing you with long-lasting protection and peace of mind.

During a backflow test, our certified technician connects specialized gauge equipment to your backflow prevention assembly. We measure pressure levels within the device to ensure that check valves are holding tight and that relief valves open at the correct pressure differential. This rigorous process verifies that the device will effectively stop contaminated water from reversing into the clean water supply during a pressure drop.

Different situations require different types of protection. The most common assemblies are the Reduced Pressure Zone (RPZ) assembly, which offers the highest level of protection for high-hazard applications, and the Double Check Valve Assembly (DCVA), often used for lower-hazard fire sprinkler systems. We can help you determine the right device for your specific property and hazard level ensuring full compliance.
