On several occasions, you may need to replace the kitchen sink drain. Leaking drains are very irritating. Likewise, replacing a collecting bowl under your sink can be quite tricky.
How To Replace Kitchen Sink Drain
This, among other scenarios, can compel you to make replacements on the drainage system. You do not have to hire professional plumbing services to do the replacement, as it is a simple task that you can accomplish on your own.
In this article, we provide a precise and straightforward guide on how to replace the kitchen sink drain.
For this task, you will require a kitchen sink drain kit, plumber’s putty, a pair of pliers, a pipe wrench, and penetrating oil.
How To Remove A Kitchen Sink Drain
Step 1: Turn off the water supply
This is a safety precaution that ensures that your work is not messed up even if you accidentally turn on the water faucet.
Block off the water supply by shutting off the valves in the sink cabinet. This step may, however, be somewhat unimportant as you will be working under the sink bowl. Therefore, you will not come into contact with water supply pipes, but precaution is of utmost importance.
Step 2: Loosening the drain pipes
The sink drain tailpiece and the P-trap are joined and held tightly together by a connector ring. To loosen the ring, a pipe wrench is required.
Hold the adjustable wrench and secure it around the connector ring and loosen it by making the wrench move in an anticlockwise direction. Loosen the connector’s grip until it is loose enough to open with bare hands. Disengage the connector ring from the tailpiece with your hands.
Tailpieces are mostly threaded. The threads lock with corresponding threads fitted on the drain strainer. The tailpiece is disconnected from the bottom of the strainer by unscrewing it in a counter-clockwise movement until it comes off.
Step 3: Remove the drain lock nut
The kitchen sink strainer is tightly secured below the sink by a locking nut. The locking nut is tightly fitted, such that disconnecting it may seem like a daunting task. Since the nut is metallic, there is a likelihood of it rusting over time due to the humid conditions. The rust makes the nut impossible to remove.
To overcome this challenge, you can spill some little amount of penetrating oil on the lock. Give the oil some time to get into the rusted threads for it to weaken the lock. It is even more appropriate to allow the oil to seep through the lock nuts overnight. Once the oil has seeped through, use an adjustable wrench to unfasten it.

Step 4: Removing the basket strainer
After taking out the locknut, the rubber washer sealing the sink’s drain hole, and friction protection, the basket strainer can then be removed. A little push is applied from the bottom of the sink to break it free from dried up plumber’s putty. Therefore, care should be taken when pushing, to avoid throwing the entire sink basin from the countertop.
Step 5: Cleaning the surface
The surface where the basket strainer rested is left dirty from gunk, rust, and scraps of the dry plumber’s putty. To prepare the new basket strainer’s surface, the putty is scraped off with a putty knife. Thoroughly clean and dry the hole once all the scraps are removed.
Step 6: Fix the new strainer
Flip the new strainer over and apply a ring of the plumber’s putty around the strainer’s neck. Carefully put the strainer down into the drain hole without messing with the putty applied.
Press the strainer down slightly to achieve an even, strong seal between the strainer and the skin’s surface. Clean off excess putty that has been squeezed off from the sides when pressing the drain strainer.
Crawl into the underside of the sink and fix the rubber-seal washer and a friction protection band and tightly replace the locknut. The locknut is tightened using a wrench while holding the drain strainer with nose pliers to prevent it from turning around.
Once the lock nut is tightened, the plumber’s putty, rubber washers, and other sealing components lie perfectly in the strainer, ensuring that the drain does not leak.
Step 7: Replace the drain pipe
Use the appropriate procedure to replace the kitchen sink drain pipe and connect the tailpiece to the drain strainer to the appropriate degree of tightness. Using a ring connector, secure the drain pipes to the protruding end of the tailpiece. Carefully tighten the connector with a wrench, and you are good to go.
Step 8: Inspect the system for leakages
Release the shut-off valves and turn on the water supply. Let the water drain over some time as you check the joints for leakages. If any joint is leaking, tighten it until the leak stops. Therefore, if you identify a leak in the sink drain, it could result in the malfunctioning of the sealing component or a loosening locking nut.
