What is backflow testing?

Backflow testing is a procedure performed by certified plumbers to verify that your backflow prevention device is working correctly. A backflow preventer is a mechanical device installed on your plumbing system that stops water from flowing backward into the public water supply. During a test, a technician attaches gauges to the device and checks that each valve is sealing properly to prevent contaminated water from entering the clean water system.

Most municipalities, including the City of Fresno, require annual backflow testing to ensure the safety of the public water supply. Failure to comply can result in fines or water service disconnection. All Star Plumbing keeps you in compliance with timely testing and proper documentation filed with local authorities.

Do I need backflow testing?

If your property has a backflow prevention device installed, you are required by law to have it tested annually. Properties with irrigation systems, fire sprinkler systems, or commercial plumbing connections are most commonly required to have backflow preventers. Even if you are unsure whether your property has a backflow device, our technicians can inspect your plumbing system and determine if one is needed or if your existing device requires testing.

How much does backflow testing cost?

Backflow testing typically costs between $100 and $150, depending on the type and number of devices on your property. This is a small price to pay for the peace of mind that your water supply is safe and that you are in compliance with local regulations.
