AirGap International has been designing, manufacturing, and supplying patented, plumbing code listed air gap units to the water treatment industry for over 30 years. Our philosophy has been to provide high performance, easy to install air gaps at a reasonable price. We offer the most diverse line of air gap products: Water softener, back washable filters, reverse osmosis, kidney dialysis, and unique connection couplings and drain line fittings.
Air gap fittings are required by plumbing code 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 and mixing and contaminating potable (drinking) water. One could think of the function of an air gap fitting as a no-fail check valve but without an internal seat or any moving parts. Properly designed and installed, air gaps, like check valves, allow water to flow only in the desired direction.
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 least reach in the back siphonage critical level (C/L) 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 back into the potable (drinking water line). The ideal air gap provides protection from back flow and back siphonage.
A true air gap is a physical separation in the drain line that one could pass their hand through. All existing air gap fittings, if properly installed, will prevent a back siphonage.
