Dishwasher Installation FAQs, answered by experts

Any drain in your house requires a water trap to prevent sewer gases from entering the home. Dishwashers don’t have an internal water trap, so they must use an external P trap. The most convenient P trap for the dishwasher is already in the plumbing under your sink.

Yes, a dishwasher needs an air gap to prevent backflow. Additionally, in many locations, air gaps or another measure to prevent backflow are required for building code compliance. There are alternatives to an air gap, like a Studor vent or a loop and trap design, but an air gap is the simplest and most popular solution.  

Your dishwasher drain hose may have a clog if your dishwasher is full of water, your dishes aren’t getting cleaned, or water takes a long time to discharge into the garbage disposal.

How long it takes to remove a dishwasher depends on how quickly you can work and the positioning of the appliance. In most cases, you can expect to remove a dishwasher in one to two hours. If the connections are older, you’ll need to use a bit more elbow grease to loosen them. This can make the process a bit longer.
