Expert Backflow Preventer Repair in Downriver Area, Michigan

A failing backflow preventer puts your drinking water at risk. Bennies Plumbing provides certified backflow preventer repair for homes and businesses in New Boston, MI 48164. We inspect the full assembly, identify worn seals, failed check valves, or damaged components, and repair what is needed to restore proper function. Many New Boston properties sit within Huron Charter Township, where all backflow repairs must be performed by a Michigan-licensed plumber and require a certified test submitted to the township's cross-connection control program. We handle that documentation on your behalf. Homes with in-ground irrigation systems are common in this area, and those systems can pull fertilizers and soil contaminants back into your potable water line when pressure drops. A repaired, properly tested assembly stops that risk. If a repair is not enough, we replace the assembly and certify it on the spot. Call Bennies Plumbing to schedule your backflow preventer repair in New Boston.

We had Nate come out for an estimate and 2 days later he was out to complete the work! Megan in the office, was very curious and professional, keeping us up to date on when the crew would arrive. The response time was timely, the service was professional would highly recommend this company!
