What is a backflow preventer and how do I know if I need testing? Backflow occurs if there is a change in pressure at a cross-connection that allows non-potable water to mix with potable water. A backflow prevention assembly ensures water flows in the correct direction. Knowing the importance of the backflow leads to the question of how often it should be tested.
The quick answer is annually. But you should know why.
To ensure functionality, backflow prevention should be inspected every year. But you also need to be mindful of any local regulations, the type of device and the systems they protect; like drinking water and irrigation systems.
Testing backflow preventers are important because:
- Regular testing helps ensure the water supply meets regulation standards
- Make sure they are properly operating and functioning
- Reduces the risk of cross-contamination
The test of a backflow is done by evaluating the plumbing systems like checking if the water flows correctly, monitors any leaks, checks water pressure and gauges. It also checks valve pressure and relief.
The life expectancy of a backflow prevention device is 5-10 years. Proper maintenance can prolong the longevity of some devices. Annual testing will help maintain proper working devices.
A backflow preventer test can only be conducted by an accredited backflow prevention service provider. Overall, testing backflow prevention devices regularly is important to comply with state and/or city regulations, detect problems early and protect water system integrity in your home.
