“Backflow” is the undesirable reversal of the flow of water and other substances from any source into the distribution pipes of the drinking water system. There are two types of backflow conditions: back pressure and back-siphonage. Backflow puts our drinking water at risk of contamination.
What is a backflow assembly?
Backflow preventers are mechanical plumbing devices installed in a plumbing system to prevent water from flowing backward in the water system. A properly installed, tested and maintained backflow preventer at the service entrance to a building or property can reliably prevent the backflow of water of an unknown quality from flowing back into the community water system. To ensure continuous proper operation, backflow assemblies are tested annually.
Am I required to have a backflow assembly?
Control of Cross-connection through backflow prevention is required in many applications. Most Irrigation water meters, multi-family housing, as well as all commercial and industrial properties are required to have backflow prevention assemblies.
Does my backflow assembly need to be tested?
If you have received a backflow test notice from your Water District, you must have the test performed within the specified time period. Even if you don’t receive a test notice, it is wise to test each backflow once a year at least.
The State of Texas requires Water Districts to have cross-connection control programs in place. These programs require that certified backflow testers check all backflow assemblies at the time of installation, after any repairs are made and annually thereafter. Backflow assembly testers are contractors who must submit a completed report to the water district following a test – pass or fail.
What happens if I do not have my backflow tested?
The most important reason to have your backflow assembly tested is for your health and safety. Beyond that it depends on the water district supplying your property. If for some reason you do not test your backflow assembly you may be cited and/or fined for non-compliance. Also, your water service may be suspended or terminated to protect the public water system
