How Can Backflow Be Prevented?

If you are asking “How can backflow be prevented?” you are looking for practical steps to protect drinking water and reduce risk. Backflow prevention starts with identifying cross-connections and installing the right backflow prevention assembly. Backflow Testing then verifies the assembly works correctly and provides the documentation that many Michigan properties need.

Backflow can be prevented by isolating cross-connections with a properly selected and installed backflow prevention assembly that allows water to flow in only one direction. Because backflow is caused by backsiphonage or backpressure, the assembly must match the risk. Backflow Testing verifies performance and supports compliance documentation.

Step 1: Identify cross-connections

A cross-connection is any temporary or permanent connection between potable water and non-potable water or substances. Common examples include irrigation lines, pools, equipment connections, and certain plumbing fixtures.

Step 2: Install the right backflow prevention assembly

A backflow prevention assembly is a series of valves configured to allow water to flow in only one direction. It helps stop non-potable substances from entering public water supplies. If a water system comes in contact with a possible contaminant, it should be isolated with a backflow prevention system.

Backflow Prevention Services installs appropriately designed backflow assemblies that meet site needs and local plumbing codes.

Step 3: Verify protection with Backflow Testing

Installation is not the finish line. Backflow prevention assemblies need to be tested on a schedule required by local authorities. Backflow Prevention Services performs testing and certification and submits documentation to the appropriate authorities on your behalf.

Testing schedules can vary by city. Some cities require annual testing, while others may allow testing every three or five years. Residential schedules can also vary by application, such as every three years on irrigation and yearly on isolation assemblies.

Step 4: Address problems with qualified repair support

If your backflow preventer is not working correctly, it could risk contaminating the drinking water supply. Backflow Prevention Services has ASSE 5110 and 5130 certified, licensed plumbers who provide expert repairs for residential and commercial customers. If an assembly fails during testing, repairs are typically quoted and scheduled for a return visit after approval.
