About Grizzly Backflow & Plumbing
Backflow Testing Company in Maryland Near Me
Backflow testing in Maryland is handled through your water utility, such as WSSC Water or a county system, under Maryland Department of the Environment rules.
Many utilities require testers to be certified and registered with them before they accept a report. Dense suburbs mean lots of irrigation PVBs and commercial RPZs. Winters bring enough freezing nights to crack an undrained device. Grizzly Backflow & Plumbing connects Maryland property owners with certified testers for annual backflow testing, PVB testing and test report filing. Call (833) 990-5874.
