I installed a Moen Caldwell bathroom faucet. I didn't tape it, and it didn't leak. I saw a link to this video looking at reviews and made a note of it. I installed a second Caldwell faucet in another sink; it had a small leak from the threads so I reinstalled adding tape. I didn't dry fit but just taped below the overflow, not doing the last half inch or so that I knew would be below the tightened ring.
Unfortunately, a very tiny leak appeared after about 2 hours. I'm klutzy with teflon tape and may have done only 3 wraps instead of 5. Rather than redo things, I unscrewed the ring all the way and added teflon pipe dope (Rectorseal T Plus 2) to the tape, then put the nut back on. That stopped the leak. It's possible that just the pipe dope would work too.
Three years later and your video continues to shine as the best on RUclips for this problem. Thanks -- I followed your simple instructions and voila! No more leak.
I do my best to make quality videos. Thanks for the compliment. Best wishes for your project.
Your video saved me a lot of pain. After spending 2 hours uninstalling and reinstalling the drain on a new faucet, I gave up. Watched this video at night and realized that I needed thread tape and some putty at the bottom to stop the water from travelling down the pipe threads. This did the trick! You got a subscriber here.
I hate to admit I spent a lot of time fiddling with my drain until I found this
I need to do this I guess, I bought a new vanity and faucet, it has a slow weep leak at the bottom, I flipped the gasket flat side up and it better but still a little water coming though. I’ll try the putty with the gasket.
Exactly what I needed, thanks so much!!! My vanity sink was leaking down the threads. I took it apart & put more plumber's putty under the sink piece. I put a little teflon tape around the threading, but not near enough, & not in the right place. Was still leaking today. So, I took it apart again, followed your instructions & put teflon tape where the gasket was, & a little plumber's putty between the sink & gasket, & that did the trick! I am so grateful for youtube, & for videos like yours that teach us how to do things ourselves!!
You are welcome, it's my pleasure to help. If you haven't already looked at the Know How Now channel page, there are many other videos that help with common home repairs. Thanks for watching and taking the time to comment!
Your video was the best! Concise, to the point! Thank you!!
You are welcome! Thanks for watching the video and commenting.
Thank you so much. I just put in a new bathroom sink with new faucet and drain. The drain leaked around the threads. Tore it all out and put in another new drain. Same problem. Watched your video, tore it apart again and followed your instructions and it does not leak. I never heard of doing it this way before. Moen needs to put this in their instructions and pay you for telling the world how to fix their problems... Thanks again.
You are welcome, Terry. I agree, it's bewildering that Moen doesn't tell you to seal the threads.
Well, to be fair, I've done a number of these over the years and never had to put tape on any of them... until now.
I would like to add, stopping leaks is a pain in the butt! I replaced everything as well and keep finding a new leak every time I turn the water back on lol
Best vid I've found for troubleshooting my leaky drain. Thanks!
You are welcome. Thanks for the compliment.
Thank you. This is exactly the problem I was having and your solution fixed it! Thanks for taking the time to make this video.

This addressed my exact problem with a Moen drain. Thanks for making this video!
You are welcome!
Quick and straightforward, saved me so much stress
I am a 35 yr old female who has never done anything plumbing related and your video on complete installation helped me replace my old faucet and drain with a new beautify black matte one for my mini remodel. I noticed today after I left the sink running for a while I had a tiny leak so I checked out this video. I feel confident when I go apply these techniques I will have 0 leaks! I forgot the gasket (I don’t think my new delta came with one) and the plumbers tape! Thank you for saving me hundreds of dollars!!!!
You are welcome, Jennifer. It's my pleasure to help. There are more plumbing videos and other home repair video on the channel.... they don't always show up on the first search result page.
I looked at a bunch of websites & videos about this issue, but yours explained & solved my exact problem perfectly! Clear & easy to follow instructions - Mahalo for your time and effort with the video:)

They make it easy to get the parts, too.
Finally a short and quick video on how to stop the leak. Thank you!
You are welcome, Mike. I respect your time, we are all busy people. Have a great day.
Very timely video for me. Was installing a Moen faucet and drain body and it was leaking at the drain body. Did a search and, fortunately, found your video. Followed instructions step by step and bingo - no leak! Thank you.

It's always great to hear the video was helpful. Thanks for the compliment!
Very concise and to the point. Thank-you, thank-you, thank-you!
You are welcome! Happy New Year!
Thank you...tried the directions on 2 other videos...yours is the only one that worked. Plumber's putty amount was the trick.
You are welcome.
Thanks so much for the clear, concise explanation of the fix!!
You are welcome, Jacob!
This technique worked flawlessly on my Moen.
I had the same Moen drain which leaked upon installation. Teflon tape and plumbers putty did the trick. Many thanks!
You are welcome!
Genius!!! Thank you so much!!!! This totally saved my sanity!!!!
You are welcome, Stacy. It's my pleasure to help.
Thank you for making these videos! Following the instructions on this video fixed my leak. I couldn't figure out what I was doing wrong until I watched this video. Great job!
You are welcome, it's my pleasure to help.
Thank you so much for posting this video. I followed your steps all the way, now i don't have leaks anymore. The Teflon tape made a huge difference. This is a must or else there would be leaks.
You are welcome. It doesn't seem to be common knowledge that the threads have to be sealed or they most likely will leak. It's always good to hear that the video was helpful, thanks for taking the time to leave a comment.
Thank you. I wish I watched this before installing and uninstalling new drain. You saved me a lot of aggravation. Thanks for sharing your skills!
You are welcome, Aaron.
Thank you. Many instructions I followed missed this step
You are welcome. I don't know why the important step of sealing the threads is often not mentioned in installation instructions.
Thanks very much. Saved me a lot of time solving the leak!
You're welcome, it's my pleasure to help.
SO HELPFUL! Thank you!!!
You are welcome!
Thank you for this video! I was on the verge of calling a plumber, you saved me a lot of money.
You are welcome, Amy. Good job! Please support the channel and subscribe, its free and it will allow me to continue to add more videos.
I put in a new Moen sink/drain earlier in the week, and just now noticed it leaking, as shown above. As you stated above, there was no mention in the directions re, teflon tape. Looks like I'll be AGAIN be taking it apart ro add the tape !
Thanks for a great video !
You are welcome. Sorry to hear you have to redo the job, though on the bright side, you know how to fix the problem.
Just bought a Moen and had this exact problem. Thank you so much!
You're welcome!
Great video
Good stuff will help me
Yes that helped me too! Teflon, teflon, teflon!
Thank you for this video - this solved my problem with my American Standard Speed Connect drain today!
You are welcome, Brooks.
Great video!
Thanks!
My husband says you are doing much better explanation that many of the videos he watched. And we’ve been working on our sink problem for almost a week
Thank you for the compliment. I do my best to make quality videos.
Thanks so much, also your accent sounds like home, ❤
You are welcome. The accent is usually identified as Philly. I live about 50 miles from the city.
Thank you thank you thank you! Worked for my replacement plastic home depot drain after wasting 3 hours in something so simple yet frustrating. I was ready to replace the whole sink!
You are welcome. Good you were resourceful and found a solution.
Thank you! A couple of things I now realize: 1) ALL leaking water must get past the rubber washer, either between the washer and the bottom of the sink, or between the washer and the threads. 2) A certain amount of water is ALWAYS trapped in the space between the threads of the drain body and the sink, from the bottom of the "overflow" holes in the threads to the top of the rubber washer. You can see this water using a flashlight with the pop up stopper removed. The washer must constantly seal it. (Of course it would eventually evaporate if the sink is unused.)
You are welcome, Bill. Thank you for taking the time to write the insightful comment. It's contributions like yours that add to the video's value. Have a great day.
P.S. Friends, besides teflon taping the hell out of the plastic threads, you may need careful use of a pipe wrench, to compress the black rubber gasket beyond Hand Tight.
And make sure the gasket is pointed upwards (flat side on the bottom) !
Thank you for the helpful video!
You're welcome!
Thank you, it's what I need!
You are welcome, Nathaniel!
Thank you! Your solution video seems to have solved my exact issue (not even Moen). Built a new bathroom and this was among the worst issues.
You are welcome, it's my pleasure to help.
Thank you for this video! I went through 2 kits and was cranking that nut so tight the washer went into the sink...lol. Frustrating. I couldn't figure out why it kept leaking there! Tape and plumber's putty did the trick. I've also seen videos where people used silicone caulk, but I didn't have any, and I wasn't making another frickin' trip to the hardware store. Anyhow, I'm going to sleep good tonight not worrying about why I was defeated by a (allegedly) simple diy project! Thank you again.
You are welcome, Ted. Sorry to hear that it's been a frustrating experience. I've "slept on a few problems" and they almost always get solved the next day on a fresh brain.
Thank you! Mine is a Kohler and slightly different but it looks like the putty did the trick!
You are welcome, Theresa!
perfect video! really sad the instructions for the drain I bought don't tell me any of this!
Going to try this tonight. I've torn apart the vanity plumbing numerous times yesterday. Also leaking at the shut off valves.
Best wishes for a successful repair. There are some videos on the channel that help with shut off valves. Click on the channel name, they are organized by playlist, click on the playlist tab to find the videos about valves.
I always have this problem, Thanks for the advise on how to solve this issue.
You are welcome, Michael.
Thank you for this simple and well explained fix. I have been battling this for too long....thiught it wasn't lined up good enough, nope...didnt think it was tight enough, broke the nut. Put tape around the threads and putty instead of silicone and 10 minutes later I can actually use my sink without a bucket underneath.
You are welcome. Thanks for taking the time to comment. Way to go on finding a solution to the problem.
Thank you so much that solve my problem
You are welcome, Dan.
Thank you so much
You are welcome, Jeff. Have a great day.
I wish I'd seen this video sooner. There are so many where they just slap those drains in with no tape or any plumber's putty. I was getting a leak at the nut and once I put the teflon tape and putty where you showed, it's finally leak free.
Great tape tip...glad you shared it with us...it helped resolved my sink leak....Thanks.
You are welcome, Jerry. It's great to hear the video was helpful.
I installed a Moen Caldwell bathroom faucet. I didn't tape it, and it didn't leak. I saw a link to this video looking at reviews and made a note of it.

It's possible that just the pipe dope would work too.
Thanks. The Teflon tape did the trick!
You are welcome, Eric. Happy New Year!
That makes perfect sense...Why didn’t I think of that? Trade school filled my head with stuff I will never use...
I can't understand why the installation instructions don't tell you to do this. There must be a lot of leaky drains.
Know How Now Thanks again...I will use this tip going forward...Maintenance is understaffed, unappreciated and certainly under paid...
content at 3:37 is what fixed my issue, thanks!
You are welcome!
Thank you!! Mine was leaking down the threads. The white tape should do it.
You are welcome, John. Happy plumbing! lol.
Great, thank you! A+++++
You are welcome, CatLady!
I wish I saw this before I used the big wrench!
Ty
You are welcome, Tony.
Thank you! I bought new Delta faucets with the worst instructions ever and ended up with this very leak. This did the trick!
You are welcome, it's my pleasure to help.
The delta larkin is very tempermental
Thank you for this video. I replaced my pedestal sink drain stopper and p trap and kept getting a leak dripping into the slip joint nut connecting the tail pipe to the p trap. I thought it was a bad alignment, used different compression washers, j bends, slip joint extensions, etc. It appeared to just be the seal between the drain stopper and nut. Finally your video solved my issues. I did have a question about the plumbers putty on the bottom of the sink between the gasket. Ive heard people state not to use plumbers putty as well as rubber gaskets together because the putty could corrode the gasket. My gasket happens to be made of silicone so I didn't know if the same concern is valid.
IMHO, I don't think the plumbers putty/gasket combo will cause a problem.
Thank you very much for the video. I'm doing apartment maintenance for my retirement job and learning how to do most things from watching youtube. I was wondering why do I have to tap the bottom of the drain tube before lining up the back where the popup rod goes in?
The thought is to unstick the putty a bit to make is easier to spin the drain body.
Thanks
You are welcome Wyatt, good luck on your new job.
Great video.....A couple of tips to throw in there.... Permatex now sells a white liquid Teflon sealant with a brush built into the cap part# 80632.... It is very sticky and will easily brush on the threads... Also if you put way too much putty under the drain lip it will clog up the over flow holes from the outside of the drain pipe where you wont see it...
Thanks for the extra tips, Chris. I encourage and appreciate comments like yours. Have a great day.
Thanks so much for this video. This solved my leak. I disassembled and reassembled my drain and could never stop the slow leak. I followed the drain manufacturer’s assembly instructions and they never mention sealing the threads where the rubber gasket makes contact. It makes perfect sense so it’s mind boggling that they leave that out. Thanks again.
You are welcome. I can't figure out why sealing the threads is not mentioned either... it must be some kind of conspiracy. lol!
You've saved another soul, and probably marriage. Thank you!
You are welcome, Mike!
Awesome video!
I bought a brand new cultured marble vanity top and faucet for a bathroom remodel. Upon testing for leaks found out a small leak originating whereby the bottom rubber gasket meets the vanity’s marble. It turns out that the surface of the marble that interfaces with the rubber gasket is rough and full of small imperfections and that is reason for the leak.
You mentioned that plumbers putty could be used to create a tighter seal between the rubber gasket and the bottom of the vanity’s marble. Would that work in this case (larger imperfections)?
Could jb-weld be used instead?
Can you sand/file the marble to make it smoother?
Thanks for the video! Any idea why mine keeps leaking from the pop-up ball joint?
Is it a new drain?
It was.. I figured it out.. the washer thingy had dropped and I hadn’t missed it.. Thanks!!😊
No more leaks thanks to your video
Good to hear you figured it out.
The putty makes sense. But can u please explain how the Teflon tape works? I don’t get how that prevents leaks. I understand it does I just can’t make sense of it in my head
The tape fills in the small gaps between the threads.
You do not need ptfe tape.Just plumbers mate and paste,slight knip job done.45 years plumbing no prob.TThe water leaking is not from thread it is from fitting and ceramic
Thanks for the video, saved my a
You are welcome, Wayne.
Turn the screw in base upside down so that the smaller end jams the gasket to the sink base.
A question ？
I found the The leaking right between the sink base and rubber gasket, which has already hardened of aging. As the waste seats are all metal, I have tried hard but couldn't remove the nut and the tube underneath away from the pipe. It seems all rusted together. Is there any way to get the nut and the pipe unscrewed and taken apart？
Thx.
You will likely have to cut it. I recently replaced a bathroom sink drain and faucet. I made a few videos. The first link is some things you can try to get that nut free. If you don't have a dremel tool. The cutting wheel is so useful. The plumber's bill will be way more than buying the tool. The dremel has saved me so many times. There are two other links showing how to replace the faucet and the drain. There are also many other plumbing help videos on the channel.

Thank you so much.
You are welcome. If you haven't already done so, support Know How Now and subscribe. It's free.
you shouldn't need putty if the waste seal and the bottom of the sink if flat. But sometimes the ceramics are not perfect.
What if the directions say to use silicone instead of plumber's putty on the wayste seat prior to installation?
Some people use silicone, especially if the sink material can be stained by plumbers putty. There is stain free plumbers putty. The down side to silicone is that you have to wait for it to dry before you can use the sink.
Know How Now thanks I went ahead and took it apart cleaned all the old Jackie silicone off of it rewrap the threads and use plumber's putty put it back together ran water through it and Presto no leaks so I am not going to use manufacturer suggestions anymore when it comes to silicone
Thanks for the tutorial video!
You are welcome! Thank you for asking that question and comments, they may be helpful to other viewers. My hunch is that the faucet manufacturer may be playing it safe, they don't want to be blamed for staining a sink. I'd contact sink manufacturer if there is doubt that plumbers putty could cause damage.
Good video, only thing you did wrong was put the Teflon tape on in the wrong direction.
Good catch, Joseph, you are correct, the first wrap of tape on the drain should be wrapped the other direction. Thanks for catching that error. For clarification the tape should be wrapped in the direction that the nut turns, if it's wrapped the other way sometimes it will crinkle up when the nut it tightened. Often, if you wrap it the wrong direction as I did, it won't bunch up when you turn the nut and no harm is done.
The sink I bought isn't flat on the bottom ( too late to return it ), so it's leaking at the black gasket..... but the directions with the drain say "don't use plumbers putty, it will degrade the plastic drain".... Silicone???
Yes, 100% silicone. The Oatey Plumber's putty container says not to use it on plastic. I did call Moen to ask if I could use the putty & they said it wasn't a problem. I suppose it depends on the type of plastic.
Why put tape at the top? And why not just use plumbers putty at the bottom instead of tape? Oh wait. Is it because it says not to use plumbers putty on plastic? I wonder if it's because it will damage the plastic or just stain it. I may try the tape first. Thanks for the tip!
I put tape on the top because I find that if there is tape on the threads it will come apart easier. I'm being nice to the next person.
The drain in the video is a Moen. I called them to ask if the plumbers putty would damage the plastic. They told me it would not. Some sinks may be stained by putty. Some people use silicon if they think the putty will stain the sink. The downside is you'll have to wait for the silicone to cure before you can use the sink.
If you don't put tape on the threads that are in the area of the black gasket, often, water will run down between the threads and the gasket and you'll have a leak.
My sink leaks from the bowl into the overfill area. I can see the water coming from the hole back down to the drain. Why is it leaking? It smells nasty and I can see the grime in the hole.
Hi Marcy, it's hard to answer the leak question without seeing what is going on.
You can clean the overflow tube with a long plastic wire tie. If the sink drains slowly, the overflow could be clogged. The over flow tube prevents a vacuum in the drain. Also, the pop up drain can collect a lot of gunk & hair. Maybe just a cleaning will get the drain running faster (if it is slow) and solve the problem. I have a video that shows how to remove the pop up, so you can clean it out.
Mine did the same thing and when I leaned over to brush my teeth it smelled like sewage. I took the drain out and cleaned out the gunk. BTW I have a Corian sink.
I did all this and it's still leaking from the bottom of the sink at the top gasket. It's holding water with the stopper down. I'm at wits' end. Turns out, the faucet is also leaking from underneath to below the sink.
So I went to try it again this morning. The drain isn't leaking anymore. Maybe the putty needed a little time to make a good seal?
The putty should make a seal immediately. It sounds like you've had a frustrating experience... maybe you misdiagnosed the leak? I'd monitor it for a while to make sure it is not leaking. Wish I could see what you are doing, a second pair of eyes is always a good thing.
@@Know-How-Now Yes, very frustrating. Having leaks in 2 spots made it difficult to diagnose. The faucet leak ran down under the basin in the back and collected around the drain gaskets making it appear the drain was still leaking. Filling the sink and draining it showed my new drain is holding. Installed a new faucet. Should hold up now until we get a new vanity. The whole thing is quite old and not plumbed correctly to begin with.
We can seal a space shuttle going into outer space and this crap is the best engineering we can come up with! Really?
Shouldn’t use plumbers putty on plastic; says so right on the packaging. I instead used silicone caulking as well as Teflon tape. I used silicon in the flange and extra tape on the threads. Am waiting for the silicone to dry now and will test. If this fails, I’m calling my landlord to send a plumber. #DYIsucks
Thanks for bringing that up, it's a valid point. I too read the plumbers putty package. I couldn't imagine how putty could break down/damage a piece of plastic. I called Moen and they said it was safe to use the putty on their product. My hunch is that the disclaimer is for some sink materials that may be stained by the putty. That's why I put the note on the video that tells you to check with the sink manufacturer. Your way is correct too, the only down side to silicone is that you have to wait for it to dry.
Know How Now Thanks for the reply. It’s too bad that warnings have to be listed on packaging when they aren’t really necessary. The putty I planned to by said in very large bold font not to use on plastic. I assumed it would compromise the pipe. Thanks for the video! Turns out the silicon and tape was effective. Your video was very helpful. :)
I just reread the Oatey label, I see the bold font that you mention. I also looked at the label for their stain free putty for use on natural surfaces & Corian. Interestingly, that label says not to use on ABS drain pipe.(ABS is the black/grey plastic pipe, I believe it is mostly used in the western US and I think Canada uses it too) It would be nice if Oatey was a little more clear on their labels.
Again, thanks for bringing the subject to my attention. I always do my best to keep the videos accurate and to give good advice. If I'm wrong, I'd want to correct the mistake. I'm not perfect, but I try to get an "A".
Congratulations on installing a leak free drain.
dang I thought I was crazy. I usually use plumbers putty. Dont know why I thought it would work without. manufactures er instructions are useless
You shouldn't have to do that if manufacturers made them better
Agreed, but most of the basin manufacturers are doing lousy job to create more job opportunity for plumbers :D
Nice wet video hopw gufnr
Plumbers putty is not for plastic hardware unless it clearly says that is OK. Great video otherwise
According to Oatey, their plumbers putty should not be used on ABS (usually black in color) pipe and acrylics. PVC is not the same as acrylic.
