Dishwasher Air Gap

Dishwasher Air Gap

Code now requires an anti-siphon device when installing a dishwasher, called an air gap. This involves creating another hole in your countertop or sink when you are planning  a remodel. Typically you install the very flexible dishwasher hose to the straight section of the air gap and tighten with a clamp. Then, install the heavy duty rubber hose on to the angled side of the air gap and to your garbage disposal. This typically creates all sorts of issues. Usually the angle to tie into the garbage disposal is not right causing undo pressure on the air gap which won’t sit right on the countertop, or forcing the airgap hose to bend excessively, causing a crimped hose and water backing up on top.  Both of these are undesired results. The fix is easy and only cost a few dollars. Buy 2  adjustable metal clamps and a 3/4″ 45 degree copper elbow. Cut the hose where the bend is most pronounced and insert the copper elbow.  You will find the 45 degree copper elbow is a perfect fit and alleviates all the issues with the crimped hose.Tighten both metal clamps onto the copper elbow and you’re done.
