In a new house build or remodel, you will find a need to create plumbing for your kitchen sink. Regardless of the sink you choose, the same steps apply to installing the plumbing pipes. The answer to why we need to do this is obvious! Everyone needs to use their kitchen sink for a variety of tasks from doing the dishes to watering the house plants. In here, we assume that any disassembly of the existing plumbing is complete. This is a project that could be tackled with one person but would go faster with two. It requires moderate knowledge of plumbing terminology.
- Adjustable wrench
- Sink strainer
- Drain pipes
- Adjustable pliers
- Straight piece
Step 1. Turn off Water
Turn off all water valves that lead to the sink cabinet. If you already have a cabinet installed, remove the cabin doors so that you have a full range of motion for the installation. Place a shallow pan under the pipes to catch any leftover water.
Step 2. Clean and Attach Sink Strainer Threads
This is where the tailpiece attaches to the sink. Clean it with a hard bristled brush so that any buildup is removed. You can then attach this sink strainer to the tailpiece. Screw clockwise in order to create a good fit.
Step 3. Connect Straight Pipe
After the tailpipe is connected, complete the same process for the straight pipe. Make sure that the threading is over the wall pipe and then hand-tighten only.
Step 4. Connect Tailpiece to Strainer
Place a slipknot on one side of the tailpiece with the threads facing up. Turn clockwise until there is a tight, secure fit. If you notice that the tailpipe is too long, that is an easy fix. Simply mark where the pipe is too long, cut it with a hacksaw, and reattach it. After you have remeasured the fit, attach it again clockwise.
Step 5. Attach Both Pipes to the P-trap Pipe
Now you can attach both pipes to the P-trap pipe. To do this, place a slipknot over either end of the P-trap pipe and add a washer. Thread the couplings to the designated attachment point. This is the drain pipe at one end and the sink tailpiece at the other end. Make sure to hand-tighten these one at a time. This makes sure that one end does not get too tight before the other end.
Step 6. Review all of the Connections
After you think you have successfully connected all of the pipes together and they are securely in place, check the connections. You want to make sure that everything looks like it has a good fit and that nothing is stressed sitting in place. After you have verified this, connect each piece with adjustable pliers in order to tighten securely. It is very important that you do not use the pliers until everything has been tightened in place.
Step 7. Turn the Water On
After everything is tested, you can turn the water back on. Make sure that there are no leaks and then you are ready to use your new kitchen drain pipes!
Doing your own plumbing work can seem daunting at first. However, breaking it down step-by-step and reviewing what needs to be done before starting the work can help lead to a successful project.
