Product Overview

Code-Approved Dual Air Gap for Water Softeners And Reverse Osmosis | Fits 1-1/2" or 2" PVC Pipe

Air gap fittings are plumbing code required to mount in the drain line(waste line) of water treatment equipment and their primary purpose is to prevent non-potable water from flowing backwards possibly mixing and contaminating potable (drinking) water. You might think of the function of an air gap fitting as a no-fail check valve but without an internal seat or any moving parts. The key characteristics for an air gap is protection from back flow and back siphonage.

Back flow occurs when there is a clog or blockage downstream in the drain line which with more water entering causes the non-potable water to back up fully engulfing the air gap unit or at least reach in the back siphonage critical level of the air gap unit. Back siphonage happens when there is suction on the potable water line and air gap inlet that sucks non-potable water port back into the potable (drinking) water line. This air gap provides protection from back flow and back siphonage. Pictured below is a typical air gap installation into a sanitary sewer pipe (note the "p-trap" which prevents sewer gas from entering through the air gap).

The air gap rule is simply this:

The softener drain line must not be connected directly to the waste system, but must be emptied into a laundry tray, floor drain, or properly trapped special outlet, preserving an air gap of at least two times the diameter of the drain line, but in no case less than 1-1/2" above the top of the receptacle used. The greater of two times the diameter of the equipment's indirect drain or 1-1/2" is the minimum air gap for whole house (point-of-entry) water treatment equipment.

The greater of two times the equipment effective drain line diameter, or one inch, is allowed for point-of-use equipment. In addition, the end of the drain line should be secured so that there is never any chance that it can become immersed in waste fluids.

Be sure to study and follow the equipment manufacturer's printed instructions. They will specify drain line size. If the proper size is not provided, the unit may not be thoroughly backwashed

Dual Air Gap For Water Softener and Reverse Osmosis Systems - Sprays Water

"The Dual Air Gap works well most of the time but during the Water Softener Backwash and Rapid Rinse cycles the fast flowing water causes a fine spray to splash out of the air gap. It's not a lot of water but it's enough to get things wet around the air gap. During the other stages where the water is not running with such force it's great. I feel like taping over the air gaps but that would defeat the purpose."

— Christopher R. (2/5)
