How to fix a leaky sink

To fix a leak under the sink, you need to put a pan down under the p-trap plumbing to catch the water that will gush out when you open up the p-trap nuts. Then you remove the long drain pipe from the bottom of the kitchen sink drain by unscrewing the retaining nut.

Is your kitchen sink leaking under rubber gasket? Then you can repair the leaky sink by using a universal drain basket wrench to remove the drain nut, then you pull the gasket and the cardboard friction washer, and push up the kitchen sink drain assembly from below, and it will pop up through the top side of the kitchen sink.
Now there will be no more leak under kitchen sink, and that is how to remove kitchen sink drain flanges.

Next you install the new kitchen sink drain flange, and go underneath to install the rubber gasket, then the cardboard washer, and finally the drain basket nut. Be sure to use one of the wrenches we link to below to tighten the kitchen sink drain basket nut.

I like he just hop into the topic at like 0:29. No fancy opening, no lengthy introduction. Awesome!

[stellalowery]

Thank you so much. I'm a 66 year old woman and I fixed my drain by looking at your video.

Just had a plumber come over to give a quote on how much it would cost to do this repair. He wanted $400! Crazy. Needless to say I have ordered the parts and tools I need from watching your video. $24 is a lot better than $400. THANK

I am in the process of replacing our kitchen faucet and luckily, while working underneath, I barely tapped the pipe and it came undone from the sink strainer drain. I noticed the gasket is all worn too. So, as a single mom, I have learned to fix many things in our house and will fix this too, thanks to your video!!!

Thank you for saving me $150 and helping me feel like a responsible diy-er! This was excellent and gave me everything I needed.

Ive graduated to the "overnight" test. Just lost my job, so I am very grateful to this video. Probably saved me a few 100 bucks. Thank you.

Jeffostroff, I appreciate you sharing your deep knowledge, no only on how to fix leaks with care and thoroughness, but also for explaining the safety factor behind the industry standards and design for the system of pipes under the sink. Thank you!

[CamsMommy]

Thank you for posting this! I had a handyman come out wanting to charge me $175 plus parts to do this. I followed your video and only spent $60 plus 20 minutes of my time. Thank you!

[richardfisher]

Good video but music volume is too high and voice/ narration is low at times. Background music detracts from the quality information you are sharing. Thank you for the video.

[joethompson]

Great job. Thanks. Replaced my laundry room drain in 30 minutes after watching this. No prior experience.

[TheocratOfPoontang]

From the bottom of my heart, THANK YOU! You saved me a $150 plumber call and now I know how to do this for life.

One trick I use to check for leaks is to use a piece of Scott blue paper shop towel. When the towel gets damp the wet area on the towel goes from light blue to dark blue. If you lay a piece of the blue towel underneath the sink, it's really easy to see where the leak is coming from. This is especially important under the sink since it's dark. It can be hard to see wet marks on a white paper towel.

I also take a piece of the blue towel and wipe around all of the joints. If the towel changes color, I know there is a leak at that point.

I love that you use terms and make it easy for a first time home buyer and 20 something to understand! You’re awesome. Thanks Jeff!

[vicloth]

Aside from the music, this video is AWESOME! I need to replace mine and I'm definitely not a DIY person. Your instructions were clear and easy to understand. I actually feel confident enough to try it myself now. Thanks!

[gloriaprice]

My husband travels a lot. I hate to bother him when in reality there's nothing he can do when not home. So thank you for this. It really helped and now I feel confident enough to do it myself. Thank you!!!
