Description
The Conbraco Industries AGD4A1 is a purpose-built air gap drain designed for use with the RP4A Reduced Pressure Zone (RPZ) backflow preventer assemblies in 1/2″ through 1″ pipe sizes. Air gap drains are a critical component of backflow prevention systems, providing a code-compliant means of safely discharging water expelled from the relief valve during normal operation or a backflow event — protecting potable water supplies from contamination.
