Durance Plumbing is certified and licensed to perform backflow valve testing and repairs in DC, Maryland and Virginia.

The Anne Arundel County Department of Public Works protects the integrity of public drinking water sources by requiring all homes, businesses, and facilities to install backflow prevention devices. Backflow prevention devices inhibit the contamination of potable water with non-potable water, solids, or gasses by preventing water from flowing backwards into supply lines at points where cross connections occur in piping fixtures.
