Do Plumbers Install Dishwashers?

Published On January 1, 2019 | By Clare Louise | Home improvement

If you already have a dishwasher, you might notice that it fits just right in its space. You might also notice that there are no pipes, plumbing, or wires showing anywhere around it. It just looks built-in.

But when it’s time to replace it, the biggest questions most homeowners have is: do professionals install dishwashers, or should I do it myself? The answer to the first part of the question is “yes”, because plumbers do install dishwashers. They are the ones you would call when you want the job done well and professionally. But if you are set on trying to install it yourself, you probably can in some cases. Here’s what you need to know.

Why you should hire a plumber

If you’ve already tried to install one yourself, you’ve probably figured out that it’s a lot harder than it looks. You often have to make new connections or alter existing ones. And if you do that, you have to know some plumbing regulations and codes to make sure it’s done correctly. In these situations, it’s important that someone who knows what they’re doing is in charge. Plumbers are required to stay up-to-date on any regulations to follow, according to experts from Speedy Rooter Plumbing.

But aside from that, dishwashers that are not installed correctly can lead to leaks or damage that you may not know about immediately. Then, you can have even bigger problems on your hands when you later discover that your walls or floors have water damage. This is a plumber’s business. They know exactly how to install a dishwasher to make sure there are no leaks and that everything is running properly.

Additionally, hiring a plumber to install your dishwasher protects you in the case that you need to file an insurance claim. If something does go wrong because of a dishwasher leak or other malfunction, whoever installed it will be responsible. Plumbers are insured to pay for such losses in the event that they make a mistake.

How to install a dishwasher

If you do decide to install your dishwasher yourself, you’ll need to know the basics. First of all, it’s best to find a dishwasher with the exact same measurements as your old one. This way, you don’t have to cut into your cabinet space. Secondly, you have to make sure you have a GFCI-protected 120-volt outlet behind the machine. If a dishwasher was already there, this should be in place. Be sure to shut off the water supply and circuit breaker before you begin.

You should also be able to locate some copper tubing under the sink that will attach to the machine. This is your hot water supply. You’ll need to connect it to a flexible tube, where your dishwasher will drain. If you have a garbage disposal, this is the most common place to find the connection.

You also need to find out whether your local code requires your dishwasher to have an air gap. This is what prevents waste from flowing back into the dishwasher. If your city doesn’t require it, you don’t need to have one, but it’s still a good idea to prevent bacteria and mold. You’ll also need to make sure that you have a shutoff valve to keep the water from flowing constantly.

Once all of these items are installed, you can easily connect your dishwasher and slide it into the opening. Keep in mind that if you buy a dishwasher with different dimensions than your opening allows for, you’ll have to make alterations. Plumbers might work with carpenters to increase the size of the opening or add trim to it to make it fit more snugly. They might also work with electricians if they run into electrical problems. Installing a dishwasher on your own is something many people can do, but hiring a professional may save you service costs and headaches in the long run.
