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>

Are all dishwashers 60cm wide?

• <div><p>Not all dishwashers are 60cm wide, but that tends to be the most common size. 60cm translates into roughly 24 inches, with most home dishwashers being between 22 and 24 inches wide. There aren’t metrics available but it’s been our experience that over 90% of household dishwashers in North America are around 24 inches wide by 24 inches tall.</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>

Job done professionally and with care. I needed a new microwave installed and wired in an older home. The cabinet above needed to be replaced to accommodate the space. Rob was efficient, friendly, and did the job far better than I could. Will definitely be contracting him again for future work.

Dishwasher Installation questions, 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.

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.

Professional services ensure correct installation, verify water-tight seals, and safely address plumbing and electrical connections in dishwashers.

Not all dishwashers are 60cm wide, but that tends to be the most common size. 60cm translates into roughly 24 inches, with most home dishwashers being between 22 and 24 inches wide. There aren’t metrics available but it’s been our experience that over 90% of household dishwashers in North America are around 24 inches wide by 24 inches tall.

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.
