Installing a dishwasher and refrigerator hookups
Now let’s move on to installing dishwasher and refrigerator hookups. Click Here for DIY repairs. We’ve already learned how to take the dishwasher waste water outlet hose and connect it to the sink drainage assembly.
If you’re building your house new, then you will have a dishwasher line already run. If you’re adding a dishwasher to a kitchen without that extra hot water line, you can simply put a T-fitting in the sink hot line as shown in the photo below.
Connect it to the intake valve as shown. The dishwasher will need it’s own dedicated 120-volt, 20-amp circuit, so it won’t have an outlet or a plug.
It is going to be hard-wired, but it’s really easy. First, remember to shut the power off before doing any electrical work. You’ll have to remove the panel on the dishwasher electric box.
From there you just connect the black wire from the dishwasher to the black wire from the dedicated circuit run. Do the same with the white wire. Connect the green wire to the ground screw on the dishwasher.
Now let’s learn how to splice into a waterline to supply water to a refrigerator for the icemaker and water through the door.
The modern refrigerators just have one line going to both the water through the door and the icemaker. It is done by putting a saddle valve onto an available cold water line.
As you can see in the picture above, you puncture the waterline by turning the saddle valve until it breaks through. It makes a watertight seal and a new waterline at the same time.
The other end just screws onto the refrigerator intake valve. You can use either copper tubing or plastic. They both work the same way.

My newsletter keeps you up to date on home construction and design ideas.
I just wanted to say that I love your website. My husband and I followed your instructions on building our own home. Most of the work we did ourselves, but not all. We saved $90,000 in labor costs and now have a beautiful home that we own.

I built my own home doing all my own labor. My house costs me around $70,000 for materials. It took me 8 months to build and is about 2,000 square feet. I didn't think I could do it, but your house web site encouraged me. I used all the info you had.
Benny Luis Lopez,
I can't thank you enough for your free information web site about home building. I was looking for Electrical wiring diagrams when I found your site. It was very helpful.

My wife and I lost our home to foreclosure but we kept a plot of land to start over. We are halfway through the construction of our house. Your website gave us hope to start over and build a house with low payments. We are in our late 60's but we find it rewarding to put so much effort into a project that will reward us for years to come.
