Dual Air Gap with Satin Nickel Brass Cap for Double Drawer or Two Separate Dishwashers with Skirted Cap and Extra Long Thread for Thick or Thin Countertops (AG200-704, AG200-X04, AMERIGAP)

A dishwasher air gap provides safe drainage of the discharge water into a garbage disposal drain. The plumbing code requires the dishwasher air gap in most states. Using a dishwasher without an air gap is not recommended. The AMERIGAP brand dual dishwasher air gap provides many advantages over other air gaps available on the market and ensures safety and peace of mind that your water supply is clean. A common misconception is that a “high loop” (routing a drain line above a sink’s flood level, for instance) and a wye connection will provide the same function as an air gap; this is not true, because the continuous connection between dishwasher and drain line still will allow back-flow through siphoning. This air gap is easy to install, easy to use, and easy to maintain. The AG200-804 air gap is UPC and IPC listed.
