• 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.
