Prepare for The Process

  • You need to start with having a clear sink underneath for doing the replacement properly.  While turning and twisting nuts, it gets really uneasy if there are things all over the place. So, make sure you keep all the tools and gears in an arranged manner.
  • Also, usually the sink underneath area is very dark. These are quite difficult to give you proper visibility. Use the portable light to be set in that space. So that when you are performing the replacement, it’s lit and easy.
  • Make sure to turn off the waterline. Next, simply drain out any water out from the system. Sometimes gunk still resides inside the line which disagrees to come out with water. Keep a bucket beneath the sink to catch them all later.

Taking Out the Drain

  • You will notice that the main drain pipe is coming out from kitchen wall. You need to find the slip nut on it.
  • Simply use a pipe wrench and loosen the nut. You should go with a counterclockwise motion to loosen down this nut.
  • Now go back to the sink’s underneath, to find out another end of this drain pipe. You need to use the pipe wrench once again to loosen nuts attached to it.
  • Using your both hands, gradually bring the drain pipe out.
  • If the drainage system is really old, it might be stuck within. In that case, use a little bit of force to take it out.

New Drain Installing

  • You need to use the plumber tape of putty for next step. Using these, simply thread down the underneath area of sink where old drain was situated.
  • Make sure to complete the threading to another end as well.
  • It’s time to set the new drain to main pipe that is coming from kitchen wall. Use the slip nut you loosened earlier to securely fit it there.
  • You need to set down the sink trap now. Simply put it back to its original position. Now make the joints for top of new drain system with sink.
  • If the drainage system is not in proper alignment with sink drains, you need to cut the tailpipe. Simply use a hacksaw to do that.
  • Put the slip nuts on the washer. Also, place nuts over the drain system’s top. Using your hand securely tighten them up. Make sure they are not too tight.

  2. Let the putty dry if you use any. Don’t go for any further step without ensuring its rock hard.
  3. If the washer is squeezing water then apply some putty to seal it. This will eventually solve the problem.
  4. To check for leaks, simply fill the entire sink. Now release the stopper and see if there are any obvious leaks. Usually, the water pressure helps to expose any hidden leak.
