Q: Do you need to drain a dishwasher before moving it?

• <div><p>If the dishwasher is in working condition, start and run a complete cycle with nothing inside. Let it drain and sit overnight before removing the hoses. In theory, it should effectively drain. You may find residual water in the hoses, but you can plug them. If the dishwasher breaks down midcycle it can sometimes be full of water. You&rsquo;ll need to manually remove the water with a plastic cup before removing the dishwasher. </p></div>

Q: Does a dishwasher need an air gap?

• <div><p>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. </p></div>

Q: How is a dishwasher professionally installed or repaired?

• <div><p>Installation includes leveling the unit, connecting water and electrical lines, securing the unit, and testing for function and leaks.</p></div>

Work was done on time. Installer was very careful to not make or leave a mess through the house. Had a couple of small things that needed to be addressed after installation, but all was good in the end.
