Backflow testing is a professional plumbing service designed to protect your water supply from contamination. Backflow happens when water flows in the opposite direction from what’s intended—potentially allowing dirty water, chemicals, or other contaminants to enter your clean water system. This can occur due to changes in water pressure, like during a main break or when firefighters use hydrants.

Professional backflow testing ensures that your backflow prevention device (a specialized valve installed in your plumbing) is working correctly and keeping your water safe.
