How To Remove Your Kitchen Sink Drain

Dripping water under your sink can be a major issue and unless you have a plumber come to fix it, we know everyone’s favorite method. We all like to grab the nearest plastic bowl and pop it under the sink to catch those droplets.

Well, we hate to break it to you but this is not a long-term solution. The rising levels of water in the bowl can be highly frustrating and it’s not practical to keep an eye on it all the time to ensure the bowl does not overflow.

How to Remove Your Kitchen Sink Drain

Luckily, we have written this article to explain, in a step-by-step guide, how to remove a kitchen sink drain and how you would go about installing it with a new one to replace it.

Instructions

Before we get started, there are several things you need to have on hand to make the job simple. You’ll need a basket or some type of wrench, a pair of pliers, a kitchen sink drain kit, penetrating oil, and a plumber’s putty.

Shutting off the Water Supply

The first step after gathering all your equipment is to shut off the water supply. You will need to find the shutoff valves located in the cabinet.

This will enable you to turn off both the cold and hot water that is supplied to the faucet. This might not be mandatory however as this section of the sink doesn’t work with the supply tubes, yet switching off the valves is still a good precaution as it ensures you won’t make a mess of your plumbing when you accidentally turn on your water faucet, especially if you have a touchless faucet.

Loosening the Drainpipes

Next, you need to loosen the drainpipes from the tailpiece. There should be a connector ring that holds in place the P-trap and the tailpiece from the drain together.

Grab your adjustable wrench and secure this on the connector to loosen it in an anticlockwise movement. Once this is loose enough, you can use your hands to disengage it faster from the tailpiece.

Disconnecting the Tailpiece

Some tailpieces on kitchen sink drains have threads that can lock in with the threads on the strainer. By turning the tailpiece in a counterclockwise direction, you can remove it entirely, unscrewing it from the bottom of the strainer.

Unfastening the Sink Drain Lock Nut

There is a locking nut on your drain and this is known as a basket nut. It is used to secure the kitchen sink strainer under your sink.

When this nut is secured tightly and the sealing components such as the plumber’s putty and rubber washers remain in good shape, you should not be faced with a leak.

Therefore, if you find yourself catching dripping water droplets, it could be a sealing component malfunction or the lock nut was not tight enough.

Using Penetrating Oil

The lock nut is made of metal and the likelihood of this getting rusty in a humid environment such as the kitchen sink can be relatively common.

If you find loosening the lock nut is too tricky after it has rusted, you can pour over some penetrating oil. This should weaken the lock for you.

Allow the oil enough time to seep into the threads of the lock nut and then pop a wrench to it. If you use the penetrating oil the night before, this will save you time waiting in the morning.

Removing the Basket Strainer

After you have disengaged your nut and taken out fiction protection and the rubber washer sealing the sink’s bottom drain hole, you can begin to remove the basket strainer.

You might only have to give it a little push from under the sink to break it off the plumber’s putty. Make sure you only apply the amount of force you really need as this will stop you from pushing off the whole sink basin off of the countertop. 

Cleaning

After removing your kitchen sink drainer, you will be left with a rather large hole and this hole will be dirty from old dry bits of putty as well as plenty of gunk. Scrape this putty off with a putty knife and wash and dry the hole in preparation to place the new basket strainer in.

Installing the New Drain Strainer

Turn your new sink drainer over and apply some plumber’s putty all around the body of it. Place the strainer into the drain hole and to get an even seal, press it down firmly.

Put some putty between the sink and the drain strainer. At this step, avoid pressing the basket strainer hard enough that the putty gets squeezed out.

Instead, clean off excess putty which has been squeezed out as you pressed down on the strainer when placing it into the hole. 

Sealing the Underside of the Sink’s Drain Hole

Now you need to climb into the sink cabinet yourself and pop a rubber-seal washer over the bottom of the strainer.

Pop a friction-protection band over the rubber washer before securing the drainer strainer tightly with the lock nut.

You need to grip the strainer with a pair of needle-nose pliers to stop it from turning round along the wrench as you fasten the lock nut. 

Linking the Drain Strainer with the Drainpipe

Once the basket strainer is secured tightly into the hole, you need to connect the tailpiece to the base of the drain strainer. For durability reasons, a brass tailpiece often works much better than plastic types.

Secure the drainpipes to the bottom of the tailpiece using a ring connector and tighten this with a wrench so that it does not crack or crack the drainpipes.

Testing

Now it’s time to test if your new sink drain is leakproof. To do this, turn on the shut-off valves and the faucet and allow the water to drain over a reasonable period of time.

As this is draining, inspect the joints for any leaks and tighten up the component if you do find yourself with dripping water.

Final Thoughts

We know a leaking kitchen sink isn’t fun and relacing it can be tricky, but we hope by reading this article you now know how to remove your old one and install a new one so that you can save your bowl for better purposes and forget about constantly checking the bowl to see if it’s full again.

Using a bowl is not a method that should be used in the long run, and relacing your kitchen sink is always advised.

If you are struggling to do this even after following our step-by-step instructions, always consult a professional.
