What Is Backflow and Why Does It Matter?
Backflow happens when a sudden drop in water pressure — caused by a water main break, heavy demand, or firefighting — causes water to flow backward through your plumbing. Without a backflow preventer, contaminated water from irrigation systems, boilers, or other sources can enter the municipal water supply. Michigan requires backflow preventers on irrigation systems and many commercial applications.
Annual Testing Requirements
Most municipalities in Wayne County require annual testing and certification of backflow prevention devices on commercial properties and irrigation systems. Our licensed backflow technicians perform the required tests, provide documentation, and submit reports to the city on your behalf. We'll remind you when your annual test is due.
Residential Backflow Protection
Homeowners with irrigation systems, swimming pools, or boilers should have backflow preventers installed to protect their household water supply. We install and service residential backflow devices and ensure they're functioning correctly to keep your water safe.
