Protect Your Water: How Often Should Your Backflow Assembly Be Tested?

You have a backflow prevention assembly installed – that's a great first step in protecting your drinking water from contamination! But installation is only part of the equation.

These crucial devices contain mechanical parts like springs and seals that can wear out, stick, or break over time. So, how often do you need to ensure yours is working correctly?

The Standard Answer: Annually

For the vast majority of residential, commercial, and industrial properties, the answer is straightforward: backflow assemblies must be tested at least once a year.

This annual testing requirement is mandated by most local water authorities and plumbing codes across the country. It's not just a suggestion; it's often a legal obligation tied to maintaining your water service.

Why is Annual Backflow Testing So Important?

Think of it like an annual check-up for your water system's safety valve. Regular testing provides several key benefits:

1. Ensuring Protection: The primary goal is to verify the assembly is functioning correctly and will prevent contaminated water (from irrigation systems, boilers, fire suppression systems, etc.) from flowing backward into the clean public water supply or your building's potable water lines.

2. Compliance with Regulations: Water purveyors require annual testing to maintain records and ensure public water safety. Failing to test can lead to warnings, fines, or even the interruption of your water service.

3. Detecting Failures Early: Internal components can degrade without any outward signs. Annual testing by a certified professional can catch subtle failures before they become significant problems, potentially preventing a dangerous backflow incident.

4. Maintaining Device Lifespan: While testing itself doesn't extend the lifespan, identifying issues early allows for timely repairs, preventing catastrophic failure and potentially more expensive replacements down the line.

Who Performs the Test?

Backflow testing isn't a DIY task. It requires specialized equipment and knowledge. Only a state-certified backflow assembly tester is qualified and permitted to perform the official test. These professionals are trained to:

• Correctly connect test equipment.

• Measure pressure differentials across the assembly's checks and relief valves.

• Interpret the results accurately.

• Complete and submit the official test report to your local water authority.

What if it Fails?

If your assembly fails the test, the certified tester will inform you. Repairs or replacement by a licensed plumber will be necessary, followed by a re-test to confirm it's working correctly before the results can be officially submitted.

Stay Safe, Stay Compliant

Don't neglect this vital maintenance task. Check your local water authority's specific requirements, but plan on scheduling a backflow test with a certified tester every year. It's a small investment that provides crucial peace of mind and ensures the continued safety and cleanliness of your water supply.
