What is Backflow Prevention and Testing?

Backflow refers to the reverse flow of dirty, contaminated water, into clean water lines. This water may contain hazardous materials such as pesticides, chemicals or human waste.

Backflow prevention is where a device is installed to stop this contamination from occurring. Backflow testing is needed to ensure the device is properly installed and tested, so it’s able to function properly. Testing usually happens annually and you can incur a fine if it’s not completed on time.

Backflow Testing and Prevention FAQs

Backflow testing time will vary depending on the property. But, typically, expect the plumber to be there for at least two hours. Tests need to be in-depth and required detailed documentation and if they find any problems, this may require extra attention.

Test are required by law, to be performed during normal business hours. This is because plumbing conditions can alter after hours.

If you fail the test, your backflow prevention system will need to be repaired or totally replaced. When the work is completed, you’ll need to have a new test and submit paperwork detailing the work done.
