How to Install a Kitchen Sink Drain Pipe Easy and Right Way

A new faucet, sink, and counter will brighten up the interior just as much as new carpet and gadgets, and for a fraction of the cost. Kudos to connections that easily screw or glue together instead of soldering or torches. Installing a new sink and faucet isn’t nearly as complex as it formerly was.

There aren’t many occasions to change the drain pipes beneath a kitchen sink, but it is not unusual to do so when the sink is being changed during a kitchen remodel.

The methods for fitting the sink drain will vary depending on how the new sink differs from the old one and what additional components are being fitted. For instance, the new sink may have a different depth than the previous one, necessitating some changes to the branch drain pipe fitting that enters the wall.

Step by Step Guide to Install a Kitchen Sink Drain Pipe

In this article, I will show you how to fix a kitchen sink drain pipe. It is a straightforward process that you can complete without the assistance of a plumber.

Items you will Need

  1. Tape measure
  2. Marker
  3. Kitchen drain trap kit
  4. PVC tubing cutter or hacksaw
  5. Channel-type pliers

Step 1: Turn off Water Supply

Are you replacing a normal sink with a deep-basin sink? You may have to lower the drain fitting in the wall to suit the lower height of the new sink drain. It is a smart option to measure the height of the trap arm on your old kitchen sink before purchasing a new one.

The first step in the installation process is to locate and shut off the main kitchen water supply faucet, then position a bucket beneath the sink to catch the water.

Step 2: Remove the Current Sink Drain

Dismantle the current sink drain pipe carefully.

  • Begin by unscrewing and unscrewing the screws and nuts that are holding the drain pipe in position.
  • To remove and disconnect the drain pipe from the kitchen sink, rotate the connections clockwise.

Step 3: Garbage Disposal

Place the garbage disposal on the sink’s preferred side. Garbage disposal generally takes up a lot of room. As a result, make sure you have enough room to incorporate it.

  • Install the basket strainer to the sink basin after it’s in place.
  • Add any other under-sink attachments, such as a hot water dispenser or a water filter, at this point.

Step 4: Tailpiece and Drain Pipe

The garbage disposal drain is connected to the tee fitting via the continuous waste line. The drain tailpiece, on the contrary, is the straight pipe that connects the sink strainer to the tiny tee fitting. Before installing the waste pipe and tailpiece, carefully trim them to length.

  1. To temporarily attach the tiny tailpiece to the sink strainer, use a slip nut and a washer.
  2. Also, use the washer and slide nut to connect the curved end of the uninterrupted waste pipe to the disposal drain outlets.
  3. Enable the pipe’s straight end to extend past the tiny tailpiece.
  4. Hold the tee up to the waste pipe and tailpiece in a gentle manner.
  5. With the help of a backsaw or a tubing cutter, cut the continuous waste pipe and the waste pipe to the appropriate length.
  6. Replace the waste pipe, tailpiece, and tee with care, making sure that the connections are securely attached.
  7. If required, make the appropriate changes to guarantee that the continual waste pipe slopes slightly downward.
  8. Using a channel style plier, secure the slip nut. To prevent harming the plastic strands, do not overtighten.

Step 5: Drain Trap Time

A J-shaped trap arm and a U-shaped trap bend are included in the drain trap. The U-shaped trap bend is attached to the drain’s bottom side, while the J-shaped trap is attached to the wall tee.

  • Bring the drain traps together firmly, then lightly tighten them with a washer and slide nut.
  • If the trap’s arm is too lengthy to fit into the available area, trim it down until it fits correctly.
  • Screw all slip nuts using a plier, being careful not to overtighten the nuts.
  • Inspect the links to the drains to ensure that they are all secure.

Step 6: Check, Check, Check

After that, run water through the sink basin to check for any leaks at pipe joints. If any leaks emerge, adjust the connection until the leak is gone. If it doesn’t work, unscrew the nut and reinsert the washer before tightening it again. Fill the skin with water and then let it flow while you carefully inspect the area underneath for any leaks.

NOTE: Ensure the trap is facing the right way up, with the sharp curve beneath the tailpiece. It may be appealing to turn it the incorrect way to squeeze it into a tight area, but it will not function correctly and will leak.

In conclusion, the installation of a kitchen sink drain pipe is not as difficult as it appears. If you have all of the major equipment for setup, it is an easy task which will only require a few minutes to accomplish.
