Frequently Asked Questions

What is the Watts 909 AGF air gap used for?

The Watts 909 AGF air gap is used with 009M1 Series reduced pressure zone assemblies to prevent backflow in water systems. It provides a physical separation between the assembly and a drain, ensuring contaminated water cannot be siphoned back into the potable supply. Common in commercial plumbing, irrigation, and industrial process lines.

What are the specifications of the Watts 909 AGF air gap?

The Watts 909 AGF is a cast-iron air gap compatible with 009M1 Series reduced pressure zone assemblies. It has female NPT connections and is designed for use with reduced pressure zone assemblies of the same series. The manufacturer part number is 909 AGF. It is not a standalone valve but a drain-line accessory.
