Step 1: Removing the old pipe

The first thing comes first; you should start by removing the old pipe. For this, place the bucket underneath the kitchen sink to collect any dripping water. The steps include-

  1. You should first open the P-trap band. It is a piece of the curved pipe. Also, there’re nuts at both ends of the band. Use pliers set to unthread and remove them. Also, you should detach the slip nut and the washer from the end of the band. Keep all the nuts and washers securely in place so that you don’t lose them.
  2. Next, you have to remove the arm of the P-trap. Find the nut that connects the arm with the drain pipe. Use the pliers set to loosen it. Then, pull it forcefully from the drain pipe. At times it may get stuck. If it happens, you should twist it a couple of times and then pull it with your hand.
  3. Many kitchen sinks come with an extension hose. It connects the sink tailpiece (straight from the drain pipe and is positioned vertically) with the trap bend. If you have one such extension, remove it too.

When you have removed all the parts of the old plumbing system, drain them properly in the kitchen sink to avoid any spills on the floor.

Step 2: Install the new pipe in the kitchen sink

Since you have removed the old pipe, it’s time to mount the new pipe into the kitchen sink. Ensure you have chosen the right fit and the connections are tight. It helps in stopping leaks.

Once you get the new pipe according to your needs, you may start working with it. The steps include-

  1. Mount the new tailpiece with the screws. It should be long enough so that you can extend it from the kitchen sink top to the wall.
  2. Sometimes the drain pipe can be on the kitchen floor. You have to raise the tailpiece and ensure that it is 2ft above the cabinet. For this, you have to cut the tailpiece. You can do it with the pipe cutter or hacksaw.
  3. Measure the length of your old pipe and cut the new pipe accordingly with the pipe cutter. Also, make sure you get the pipe that matches the kitchen sink hole’s diameter.
  4. Attach the new pipe with the sink and tighten it with the nuts and washers. Finally, you have to attach the P-trap correctly.
  5. For this, connect one end of the P-trap with the tailpiece. Then, swivel it and attach it with the drain pipe. Finish off the job by tightening the nuts.
