9 Steps to Install a Double Kitchen Sink Plumbing:
Here are the materials required:
- Brand new double sink
- Compression nuts
- PVC Pipe
- Sanitary Tee
- Kitchen drain trap kit
- Plumber’s Puffy (or Teflon tape)
- Silicone sealant
Here are the tools that will come in handy:
- Measuring Tape
- Safety glasses
- Pipe wrench
- Puffy Knife
Step 1: Gather All the Necessary Tools and Materials
Before starting any plumbing activity, you need all the necessary tools. If you don’t have all the tools, you can buy or rent them from a nearby home improvement shop.
Since kitchen sink kits have different types and sizes, consult the store attendant to confirm that you are buying the right tools.
You can get plastic or metallic compression fittings, but most plumbers prefer plastic fittings because it doesn’t corrode and is easier to use. You can get a double bowl kitchen sink drain kit if you desire.
Step 2. Turn off the Water Valve
Before beginning a double bowl sink to one drain installation, you need to turn off the water valve. The water valve is found below the sink. If you can’t find it, you must turn it off from your house’s primary water supply line.
Step 3. Mount Drain Assembly
You have to mount the drain assembly. It comprises flange and popup (also known as the stopper), the key body beneath the sink, and the ball-and-roll system that regulates the stopper’s movement.
Prior to fixing the sink in the cabinet, you have to mount the drain assembly in the wall opening at the bottom of any of the sinks.
You still have to install the garbage disposal system in the other wall opening. Apply the plumbers puffy to make each hole leakproof. You should tighten the screws with a plier.
Step 4. Mount the Double Bowl Sink
Fit the sink into the cabinet. Clips usually come with sinks. Use a screwdriver to drive the clips into the cabinet.
Step 5. Install the Garbage Disposal
The next step is to install a garbage disposal. Installing garbage disposal may seem complicated, but you can look it up from your manufacturer’s manual.
Additionally, you will find the steps to install garbage disposal comprehensively covered later in this article.
Step 6. Mount the Tail Section
You need to fix the tail section now without the disposal system. Use a slip nut to connect the tapped outlet.
The slip nut is a gentle threaded ring that can be attached by hand. While installing it, you need to be careful.
Step 7. Link Sanitary Tee to the Tailpiece
It would help if you used a plastic compression nut to connect the sanitary tee to the tailpiece. You can adjust the compression with your hands.
To determine if the tailpiece is firmly attached to the tee, insert a compression washer.
Measure the distance between the tea outlet and the disposal system with a measuring tape. Next, use a hacksaw to cut a piece of pipe, as the length, to connect the tee and the disposal system.
To ensure airtight connection on either end, don’t forget to use compression nuts and washers. Try to be careful when cutting the pipes.
Step 8. Fit in the P-Trap
Before wrapping up the process, insert the p-trap assembly into the lower edge of the p-trap.
Next, fit the p-trap to the drain inlet on the wall. Cover the p-trap with an adapter to prevent leaks. So, you see, double sink p trap installation is not complex.
Step 9. Test-run the Sink
It’s important to test run your kitchen sink to check for leaking. To test-run, turn on the water. If you experience leaks, no need to worry. You just have to tighten the screws and apply the plumber’s puffy.
If it still occurs, remove the screws, and reposition them, and re-tighten the screw.
Plumbing a Garbage Deposal with Double Kitchen Sink
To plumb garbage disposal with a double bowl kitchen sink, you may require the following material:
- A garbage disposal unit
- A putty knife (plastic one)
- Wire nuts
- An old rag (or piece of cloth)
- Plumber’s putty

Step 3: Detech the couplers that connect the extension pipe of the drain and p-trap
Take slip pliers to perform this operation. Next, keep these drain parts in a safe place. Insert a piece of cloth in the drain to stop a foul smell from polluting your kitchen.
Step 4: Unscrew the nuts beneath the drain coupling
Use your pliers to do this. When it’s loose enough, remove it by pushing it up. Separate the flange of the drain from the lower part of the sink.
Step 5. Scrape off some puffy residue on the drain hole. Use the scraping knife.
Step 6. Apply a good amount of puffy around the flange of the garbage disposal unit.
Step 7. Insert the flange in the correct hole in the sink. Use the mounting ring to put it in place
Step 8. Tighten any screws using a screwdriver. Finally, you’ve installed your garbage disposal unit.
