Backflow preventers are mechanical assemblies installed within a plumbing system to stop water from flowing in the wrong direction. When pressure changes occur—during line breaks, fire suppression events, irrigation demand, or municipal supply issues—these devices act as the last line of defense protecting drinking water from contamination.

Because they are mechanical, backflow preventers require routine testing, maintenance, and eventual repair or replacement to remain compliant and effective. Failure isn’t always obvious—but the consequences can be immediate, costly, and regulated.

We have specially trained and licensed technicians who can inspect, repair, and certify your mechanicals quickly, safely, and reliably to make sure they are performing as expected.
