Very professional and transparent. I hired him to install a new garbage disposal and angle stops. He explained which disposal would work best for me and found me some great prices. Super clean work I felt I had a brand new kitchen after he left.

Dishwasher Installation questions, answered by experts

To create a siphon break and remove any chance of dirty sink water or water that backs up into the sink from getting into your dishwasher, your dishwasher drain hose needs to have a high loop or an air gap device as part of its installation. All building codes require at least a high loop. In many places, it’s necessary to install an air gap device to meet the code.

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.

Costs depend on labor rates, replacement part prices, brand, and whether emergency service is required.

Regular use helps keep interior dishwasher parts functioning properly and the interior clean. Try to run your machine at least once every two weeks as part of your dishwasher cleaning schedule.

Every six months, running two cups of white vinegar through your dishwasher (place the vinegar where you put detergent) will help deep clean the unit to boost performance.

Local plumbing codes and manufacturer recommendations typically dictate the minimum distance between a sink and a dishwasher. This is generally 18 to 24 inches, providing enough room for easy loading and unloading of dishes without hindering the sink's function. Maintaining this separation not only adds convenience but also reduces the chances of water damage and optimizes plumbing connections.
