Conbraco AGD4A1 Air Gap Drain
The Conbraco AGD4A1 Air Gap Drain is a specialized plumbing component designed specifically for 1/2" to 1" Apollo RP4A series reduced pressure zone backflow preventers. This RP4A air gap drain serves the critical function of collecting minor nuisance discharges from the relief valve, preventing localized flooding while maintaining the required atmospheric break. Engineered from high-impact materials, the AGD4A1 ensures that the RPZ valve drainage system complies with plumbing codes regarding physical air gaps between the relief valve port and the waste line. Installation is straightforward via the integral bolt-on mounting, ensuring a secure, leak-proof connection to the backflow body. By channeling relief valve discharge directly to the floor drain, this backflow preventer air gap protects sensitive equipment and surrounding infrastructure from water damage during standard pressure fluctuations or backflow relief valve activation. This is a must-have for commercial mechanical rooms and industrial HVAC installations where precise drainage management is required.
Key Technical Benefits
- System Compatibility: Precision engineered for seamless integration with 1/2", 3/4", and 1" Apollo 4A-200 series RPZ assemblies.
- Corrosion Resistance: Manufactured from durable materials resistant to mineral buildup and chemical exposure in harsh mechanical environments.
- Code Compliance: Facilitates the necessary air gap requirements for safe discharge into a gravity-fed drainage system.
- Simplified Maintenance: Features a low-profile design that allows for easy inspection of the relief valve seat and sensing line without removing the drain.
Common Questions
Q: Does the AGD4A1 handle full-flow relief valve discharge?
A: No, this unit is designed to manage nuisance drips and minor fluctuations. For a full-bore relief valve failure, the floor drain capacity must still meet the maximum potential discharge rate specified by the RPZ body.
Q: Can this be installed on 40-200 series valves?
A: The AGD4A1 is specifically optimized for the newer 4A series (RP4A) backflow preventers. It is recommended to verify the bolt pattern alignment for legacy series before installation.
Q: Is specialized hardware required for mounting?
A: The drain is designed to bolt directly to the relief valve flange, utilizing standard Apollo backflow parts architecture for a secure fit.
