Watts 909AGF – Frequently Asked Questions
1) Which Watts backflow preventers does the 909AGF air gap fit?
The Watts 909AGF air gap fits 1-1/4 through 3 inch 009 and 909 Series reduced pressure zone assemblies, 1-1/4 through 2 inch 009M1, and 2 inch 009M2. If your assembly falls outside those sizes and series, this is not the right air gap fitting.
2) What size drain connection comes off the Watts 909AGF air gap?
The outlet is a 2 inch female NPT threaded connection, so you can thread 2 inch male NPT pipe or a 2 inch adapter directly into it to carry relief discharge to the floor drain. Size your indirect waste line and drain accordingly.
3) Do I need an air gap fitting on a reduced pressure zone backflow preventer?
Most plumbing codes require the relief valve discharge from an RPZ to reach the drain through an air gap so nothing can siphon back into the assembly. The 909AGF bolts under the relief port on 009 and 909 Series assemblies and converts that open discharge into a piped 2 inch connection you can run to an indirect waste receptor, instead of letting the relief dump onto the floor.
4) Is the Watts 909AGF air gap certified lead free for potable water?
The 909AGF is not in scope for lead free requirements. It sits on the relief valve discharge side of the backflow preventer, handling waste water to the drain rather than water going to fixtures, so the potable lead free rules do not apply to it.
5) Does the Watts 909AGF air gap meet Buy American Act requirements for a federal job?
No. The 909AGF is not Buy American Act compliant, so on a federal or BAA-restricted specification you will need a compliant alternate for the air gap fitting.
6) What part number do I order for a Watts 2 inch 909 air gap?
Order model 909AGF, Watts part number 881378. One model covers the whole range, from 1-1/4 inch up to 3 inch on the 009 and 909 Series, so there is no separate size to specify.
7) What is the Watts 909AGF air gap made of?
Cast iron body. That holds up in mechanical rooms and backflow enclosures where the relief valve may dump hot or cold water intermittently, and it matches the weight of the 009/909 Series assemblies it mounts to.
