Johnson Industries holds the patent and is the sole manufacturer of the Johnson Tee Air Gap created to prevent sewer back flow into a residential dishwasher. The Johnson Tee is an ASPE approved alternative venting system for dishwashers, and has been popular throughout Western Washington for 25 years. The Johnson Tee replaces the traditional deck-mounted air gap, which usually sits to the left or right of the kitchen sink. With today's clear and elegant sink designs, an unsightly air gap can and should be eliminated from the kitchen counter entirely, with the Johnson Tee providing an unobstructed faucet. The Johnson Tee vents away from view typically through an outside wall. This inexpensive piece of equipment is the perfect accessory for every kitchen design concept: from rustic country sinks to deep commercial grade drop-ins.
