Do You Need a Backflow Preventer?

A backflow preventer may be required at a cross-connection to prevent contamination of the drinking water source. It is used to protect the community water supply from contamination that occurs from backflow. Water is typically maintained at a significant pressure to allow free, consistent flow from all fixtures in your building. At times, this constant pressure may be reduced when a water main bursts, pipes freeze, or there is an unexpectedly high demand on the water system. When this change in pressure occurs, contaminated water from unsanitary sources could be drawn up into the public water system.

To avoid this potential hazard, municipalities and county authorities may implement a backflow program. If your district is included, we invite you to work with Water Doctor’s licensed Master Plumbers and backflow technicians. When it comes to your water supply, you can rely on our team of experts who have had professional training and certification in backflow prevention throughout Maryland—including Annapolis, Gaithersburg, Bethesda, and the surrounding areas.

Backflow preventers are most commonly required with:

• Irrigation systems
• Laboratories
• Water treatment systems
• Chemical tanks
