Backflow Preventer Device/Valve (Underground)

The Below-Ground Backflow Preventer Vault prevents potential cross-connection hazards that are found in potable, fire protection, irrigation, and industrial water systems. Codes require a backflow prevention device where these hazards exist.
Pre-installing the backflow preventer in a highly secure precast concrete vault provides quick installation and long-term protection for this critical component, while simultaneously protecting the public water supply.
