Washington DC Backflow Testing

DC Water requires backflow prevention devices and testing for certain types of properties, including:

  • Properties with fire sprinkler systems
  • Properties with irrigation systems
  • Properties with large boilers or chillers
  • Properties with chemical or fuel storage tanks
  • Properties with industrial processes that use water

DC Water requires backflow testing to protect the public water supply from contamination caused by backflow.

Additionally, failure to comply with DC Water’s backflow prevention device testing requirements can result in fines and legal action.

What is Backflow Testing

Backflow is the reversal of the normal flow of water in your plumbing system, which can occur when there is a change in water pressure. This can cause contaminated water to flow back into your plumbing system, which can pose a serious health risk to you and your family

In conclusion, backflow prevention devices and testing are an important aspect of maintaining a safe and healthy plumbing system. If you own a property in Washington DC that requires a backflow prevention device, make sure to have it installed and tested annually by a licensed backflow prevention device tester. Failure to comply with DC Water’s requirements can result in fines, legal action, and even the shutdown of your water service.
