Best dishwasher installation pros near Park Forest, IL

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.  

A clogged air gap can cause a dishwasher not to drain. There are, however, other potential issues that can lead to improper drainage. For example, if you have attached the air gap to a garbage disposal and forgotten to remove the knockout plug, wastewater may backflow into the dishwasher. Check that the air gap is installed properly, and then look for clogs in the air gap and dishwasher filters. 

Many people think this question relates directly to their electricity bill. Running your dishwasher at night both keeps your bill lower and is better for the environment. Energy rates tend to be much lower during off-peak hours. These hours are usually from 9 at night until around 6 in the morning. Your local utility provider will be able to tell you which hours are considered peak and off-peak. In conclusion, running your dishwasher during these off-peak hours is both better for your wallet and requires less energy from the grid, which is better for the environment.
