Types of Dishwashers
Before we dive into the plumbing installation, let’s take a quick look at the different types of dishwashers available on the market. There are three main types of dishwashers:
- Built-in dishwashers: These dishwashers are designed to fit under a countertop and are permanently installed. They’re the most common type of dishwasher.
- Portable dishwashers: These dishwashers are on wheels and can be moved around the kitchen. They’re an excellent option if you don’t have the space for a built-in dishwasher.
- Countertop dishwashers: These dishwashers are small and designed to sit on a countertop. They’re an excellent option if you have limited space in your kitchen.
Now that we’ve covered the different types of dishwashers, let’s move on to the plumbing installation.
Plumbing Components Required for Dishwasher Installation
To install a dishwasher, you’ll need the following plumbing components:
- Water supply line: This is the line that connects your dishwasher to the hot water supply. The water supply line should be made of copper or braided steel.
- Drain line: This is the line that carries wastewater from the dishwasher to the drain. The drain line should be made of PVC or another type of plastic.
- Air gap: An air gap is a device that prevents wastewater from backing up into your dishwasher. It’s a mandatory component in many areas.
- Drain hose: This is the hose that connects the dishwasher to the drain line. The drain hose should be made of high-quality, flexible material.
- Plumbing fittings: You’ll need various plumbing fittings, such as compression fittings and hose clamps, to connect the water supply line, drain line, and drain hose.
- Dishwasher installation kit: Most dishwashers come with an installation kit that includes all the necessary plumbing components. If your dishwasher doesn’t come with an installation kit, you’ll need to purchase one separately.
Now that you know the plumbing components required for dishwasher installation let’s move on to the installation process.
