DIY Plumbing Project: Piping a Double Kitchen Sink Made Accessible


When it comes to kitchen sink plumbing, having accessible pipes is essential for efficient drainage and preventing potential clogs. In this blog post, we will guide you through a step-by-step process on how to pipe a double kitchen sink made accessible. With a few tools and some basic plumbing knowledge, you can complete this DIY project in no time!

Gather Your Tools

Before diving into the plumbing work, make sure you have the following tools and materials on hand:

  • Adjustable wrench
  • Plumber’s tape
  • Hacksaw
  • PVC pipe cutter (if using PVC pipes)
  • PVC pipes/fittings or metal pipes/fittings
  • P-trap assembly
  • Plumbing primer and cement (if using PVC pipes)

Step 1: Remove Existing Plumbing

Begin by turning off the water supply to the kitchen sink. Use an adjustable wrench to disconnect the water supply lines from the faucet. Then, remove the existing pipes and P-trap assembly from the sink drain.

Step 2: Measure and Cut Pipes

Measure the distance between the two sink drains and the location where the P-trap will be installed. Mark and cut the pipes accordingly, using a hacksaw or PVC pipe cutter if necessary. Remember to measure twice and cut once for accuracy.

Step 3: Prepare Pipes and Fittings

If using PVC pipes, apply plumbing primer to the outside of the pipe and the inside of the fittings. Then, apply PVC cement to both the pipe and fitting before connecting them. Twist the pipe slightly to ensure a secure and tight fit. If using metal pipes, use plumber’s tape to create a watertight seal between the pipes and fittings.

Step 4: Install the P-Trap Assembly

Attach the P-trap assembly to the bottom of the sink drain. Ensure it aligns properly with the pipes and is tightly secured. The P-trap is essential for trapping debris and preventing sewer gases from entering your kitchen.

Step 5: Connect Pipes to Sink Drains

Connect the cut pipes to the sink drains, ensuring they are secure and aligned correctly. If using PVC pipes, twist the pipes slightly while connecting to create a tight fit. For metal pipes, use adjustable wrenches to tighten the connections.

Step 6: Test for Leaks

Once all the pipes are connected, turn on the water supply and check for any leaks. If you notice any leaks, tighten the connections or reapply plumbing primer and cement if using PVC pipes.

By following these steps, you have successfully piped a double kitchen sink, making it more accessible and efficient. Remember to maintain your plumbing regularly and address any issues promptly to avoid costly repairs.


Piping a double kitchen sink made accessible is a DIY plumbing project that can be accomplished with some basic plumbing knowledge and the right tools. By correctly installing and aligning the pipes and P-trap assembly, you ensure efficient drainage and prevent potential clogs. Always remember to turn off the water supply, measure accurately, and test for leaks to achieve a successful plumbing project.
