Why does a dishwasher have to drain through the sink plumbing?

• <div><p>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.</p></div>

How long will it take to install my dishwasher?

• <div><p>Installing a dishwasher should take one to four hours, depending on the complexity of the installation and whether you DIY or hire a pro. Even if you're particularly handy, installing a dishwasher on your own will likely take longer — at least two hours. On the other hand, a professional can likely install a dishwasher in about an hour. Installation time will take longer if you have to remove an existing dishwasher, reroute plumbing, or repair damaged flooring underneath the appliance.</p></div>

DNY was extremely professional and did a great job. They were able to get my old dishwasher out and put my new one in after another company claimed it couldn’t be done. I appreciate their work ethic and will definitely be using them again.

Dishwasher Installation questions, answered by experts

Only if the dishwasher isn’t made of stainless steel. The corrosive chemicals in bleach will stain stainless steel and can also cause further damage. To stay on the safe side, stick with an extra cycle of vinegar to banish any lingering odors.

The correct water temperature for your dishwasher depends on the washing phase. When water enters the machine, it should be around 120 degrees Fahrenheit, but no hotter than 150 degrees. During the wash cycle, the machine will heat the water to between 130 and 140 degrees. If your dishwasher has a sanitizing cycle, the water can reach a temperature of up to 180 degrees.

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.

To extend the lifespan, clean filters regularly, run cleaning cycles with vinegar, avoid overloading, and check for leaks.

Installing a dishwasher should take one to four hours, depending on the complexity of the installation and whether you DIY or hire a pro. Even if you're particularly handy, installing a dishwasher on your own will likely take longer — at least two hours.
