AG140-002 Water Softener Air Gap for installation in Washing Machine box with 1-1/2-inch Drainpipe

❤ EASY TO CONNECT: The AG140-002 is a water softener air gap that is designed to share the drainpipe with a washing machine discharge tubing. It has a 1/2-inch OD inlet port that is designed to fit 1/2-inch schedule 40 PVC slip fitting with O-ring, and a 3/4-inch OD outlet. To ensure secure mounting on vertical wall or to back of outlet boxes, a wall bracket and four Phillips Pan Head Screws are provided. The AG140-002 allows space for washer drain hook or soft rubber or plastic washer hose.

❤ STANDPIPE CONNECTION: The AG140-002 comes with a 4-inch long, 7/8-inch ID flexible rubber hose that fits onto the air gap’s 3/4-inch OD outlet. It is designed to fit into recessed washing machine outlet boxes with 1-1/2-inches or 2 inches standpipe. The air gap is tested at 15 gallons per minute and recommended usage is 7 gallons per minute.

❤ SPLASH PROTECTION: The AG140-002 air gap uses splash guards to assure a completely dry operation. Splash guards are an integral part of the design and can be seen through the side air gap window. During water softener operation, an initial discharge surge can create splashing. Splash shield eliminates the possibility of water splashing outside of the air gap. When designing drainage for an air gap, makes sure that P-trap is located minimum 20-inches from the top of the standpipe.

❤ QUIET OPERATION: When water exits the air gap, depending on the design, it may flow directly into a P-trap. This can create splashing noise that may be objectionable. The AG140-002 air gap is designed with a flow straightener to quiet and smooth out turbulent flow. Also, to avoid excessive noise, it is recommended to use 22 degrees elbow inline with standpipe to avoid direct drainage to P-trap. The pipe elbow should be located at least 12 inches from the air gap to eliminate splashback.

❤ CERTIFICATION: The AG140-002 is legal to install in any state. It is UPC® (Uniform Plumbing Code) Listed, IPC® (International Plumbing Code) and NSF® (National Sanitation Foundation) tested. These certifications assure that every product is safe to use. Also, all of the products are tested for strength and to make sure that every glue joint will withstand at least 40lb of force and not break. The testing is conducted for every manufactured lot to ensure consistent performance.
