FEBCO Plastic Air Gap Drain Kit 3/4 in. – 2 in. for 825Y

This 3/4 to 2 inch plastic air gap drain is installed under a reduced pressure assembly, series 825Y, to catch minor relief valve discharge due to pressure fluctuations and/or minor check valve fouling. This drain reduces the amount of water splashing in the area around reduced pressure assemblies while funneling relief valve discharge into the drain.
