Watts 111764 – Frequently Asked Questions
1) Which Watts backflow preventers does the 0111764 air gap fit?
The Watts 0111764 air gap is made for 957 Series reduced pressure zone assemblies in sizes 2-1/2 inch through 10 inch (65 to 250 mm). If your RPZ is smaller than 2-1/2 inch, this is the wrong air gap for the body.
2) What size drain line connects to the Watts 0111764 air gap?
The outlet is a 2 inch (50 mm) female NPT threaded connection, so it mates to 2 inch male NPT pipe or a 2 inch male adapter on your indirect waste line running to the floor drain or sink.
3) How much clearance do I need under the relief valve to mount this air gap?
Plan the funnel footprint first: the air gap is 7-1/2 inches (190 mm) in diameter, so it needs that much clear space beneath the relief vent of the 957 assembly, plus room below for the 2 inch drain connection and the physical air break to the receptor. Tight vertical installs between the valve and a wall or floor are where this gets caught.
4) What part number do I order for the Watts 957 air gap in 2-1/2 to 10 inch?
Order Watts 0111764, manufacturer part number 111764. One part covers the whole 2-1/2 inch through 10 inch 957 range, so facilities standardizing on Watts RPZs across several sizes can stock a single spare.
5) What is the Watts 957 air gap funnel made of, and will it hold up in a mechanical room?
Body is black plastic. It handles intermittent relief discharge and condensate drip from the assembly, and it will not corrode the way a metal funnel can in a wet mechanical room or backflow pit.
