Thread: Dishwasher Air Gap

  1. #1

    Default Dishwasher Air Gap

    Question for anyone:

    Due to the positioning of my dishwasher, garbage disposer & drain traps, the air gap on the deck of my sink is directly behind the GD, but the drain inlet for the DW is pointing to the left.

    As the 7/8ths hose from the gap to the GD is not very flexible I was wondering if there is another hose option. What I have will work, but it does fight back and I am concerned it may break the outlet on the gap. Or am I being to cautious?

    Get a longer hose to releave the strain.

    you can make 45 and 90 bends using 3/4 copper fittings. Stub an inch of copper out of each end of the ell. The 7/8" diameter is a perfect fit in the rubber hose. These fittings will have negligible effect on the flow, whereas a slight kink when making large turns in the hose is big trouble!

    You might also consider using preformed (as in curved) automotive heater hose which should be available in the diameter you need. At least you won't have to worry about kinks.

    Jimbo,

    I'm in Wisconsin. Are you aware of any code issues with using a 3/4 elbow? I still have a final inspection to pass. Thanks.
