Backflow Preventer Installation & Maintenance

Drinking water flows from the City’s distribution system into a property’s private water system. Backflow is the undesired reversal of water flow between the City’s distribution system and a private system, due to changes in water pressure. This reversal or “backflow” can cause contaminants to enter into the drinking water distribution system.

A backflow preventer is a requirement by the city that will impact approximately 15,000 industrial, commercial, institutional and multi-residential properties.

We are completely qualified and certified to install & maintain backflow preventers. After an installation, testing and maintaining is required annually.
