Dishwasher air gap
Posted by Chuck on February 28, 19101 at 11:41:44:
It is my understanding that the air gap is necessary when hooking into the sink tailpiece.
If there were a trap below the subfloor (basement, crawlspace), wouldn't that make the air
gap unnecessary? The dishwasher I removed had a trap below it with flexible discharge hose
connected directly to the trap. I'm changing to an island vent setup. Couldn't I hook it up the
same way?
