Dual Air Gap for Double Drawer or Two Separate Dishwashers with Skirted Cap and Extra Long Thread for Thick or Thin Countertops (AG200-004, AG200-001, T52, AMERIGAP)

If you have a double dish drawer dishwasher and one won’t drain, this could be what you need.

Solves the two dish washer air gap problem. Don’t need two holes in counter top for two air gaps and save having to figure out where to put second drain.

Easy to install works great

The air gap installed easily and did the job!

This air gap worked with our dual dishwasher setup for few months before the dishwashers started throwing error codes that they weren't draining properly.This design is actually odd in that the air gap isn't actually a "gap" as you might expect - the drain is not open to "air" under the cap. If the drain line (or disposal) plugs, drain water will back up into the inlets - it can't flow out the front of the cap into the sink. Furthermore, in my opinion the geometries of this gap are too small and prone to blockage by debris.There actually aren't a lot of dual dishwasher air gaps out there, but it turns out this manufacturer makes another model "ET200-002" which I'm much happier with, addresses issues noted above (vented to air, larger space for debris to flow) and drains far better. Since it's not a sealed unit, ET200-002 does gurgle noticeably as it drains - but not overly so. It is also a physically larger cap, sticks up a bit more off the counter. Acceptable trade for not having these sort of dishwasher drain issues...

How do I order a copper cap for this? Description says colors are avail.
