Coupling 1-1/2 pipe with 1-1/4 pipe using reducer washer | how to hook pipes of different diameters
HTML-код
- Опубликовано: 5 июн 2021
- There is something magical called a reducer washer. In this video, I will show how to connect a bathroom sink of diameter 1-1/4" (1.25 inches) with downstream sew pipes of 1-1/2" (1.5 inches) via the help of a reducer washer.
The reducer washer can be purchased from Amazon: amzn.to/3pug3JF
In United States, most kitchen sew pipes are 1-1/2" in diameter whereas their bathroom sink counterparts are 1-1/4" in diameter. Somehow the sew pipes in my bathroom are of the diameter of the kitchen ones. My plumber said he couldn't hook up my drain with the sew pipes, specifically the P- trap, unless I can get a 1-1/2" drain, which doesn't exist for bathrooms.
He is wrong.
Update: The company that did the work for me is called Staring Point Construction LLC based in west Des Moines, Iowa. If you are in Iowa or Midwest, avoid them. They asked me for full-project money before finishing. The quality of their work is below average and they have almost no sense of customer service. The bathroom they remodeled for me leaked after one week. The bathroom tiles they put on my shower is crooked, uneven. They promised to fix the issues I raised but they never come back.

You saved my sanity. I'm doing the same thing and stood staring at the various parts in Lowe's not knowing which one would do the job. This is exactly what I need!
Literally standing in the plumbing aisle of Lowe’s watching this too. Haha
I like how he said he was standing for "15 min" at the hardware store. I spent more time walking back and forth to find the 1-1/4" washers that I then found out would NOT work! LOL
Your J-bend is installed backward
That was exact problem with my dumb contractor/ handy man. He said he knew how to do it, but didn't know. I fixed the problem with same way. Took me couple trips to Homedepot and finally I solved the problem last month. Today I saw this video. It turns out many people didn't know how to fix this. Thank you for the video.
Silly me! My intuition told me there was a solution, but thank you for confirming! Running water here we come!
This is EXACTLY what my problem was and that’s was definitely the solution! Great video, keep it up!
This was exactly my problem and you offer exactly the needed solution. The contractor who did the original installation was either too ignorant or too lazy to install the needed reducer.
I was going crazy trying to find a video to help me with this problem. THANK YOU!!!
A bit weird, I just hit this issue with a new sink, thinking about it and then this video popped up on my feed about an hour later. Thanks for the info. Very helpful.
This is exactly what I need. My bathroom was plumbed with 1/2 inch.
FINALLY!! I've been to Home Depot exactly 5 times trying to solve this issue. Thank you!!
I will be making my fourth trip tomorrow…lol
I’ve never understood why bathroom faucet drain kits don’t just come with 1 1/2” pipe rather than 1 1/4”! These reducer washers are life savers!
This is EXACTLY what I needed!!!! Thank you for posting this information.
This came in handy man. New house and previous owners just patched everything up to pass inspection. I had a lot of old moldy water under the sink and couldn’t figure out how to stop the leak thanks. BTW the “Oatey” brand 1-1/2 comes with the reducer washer included in the package
Thank you very much for the video! This was my exact problem. I actually had a reducing washer in the basement and it worked perfectly!
You're the man, bro. Thank You!
I've been searching around to fix this problem. I never thought of the reducer washers.
Sorry to hear that happened to you. I appreciate you making the video exposing them
Great advice on the gasket reducer. However your p-trap is installed backwards.
Man this video helped me sooooo much !! Thank you !! I needed that reducer washer too 🤦🏽♀️
Thanks for your video. Super helpful, this worked exactly right for me. Thank you.
This is exactly the information I was looking for! Thank you for making a video.
Finally got my answer and explanation, after calling around. Thanks!
your J bend is flipped the wrong way.
Very helpful thanks. A plumber family member gave me the same bad advice 😂
Thank you! If I had watched ur video, it would have saved me 3 trips to Home Depot 😅
Nice to know there is a community of people with this issue and no just me lol 😆
Thanks a lot that was my problem and now I fixed God bless you!!!
Thank you for your help!! I was able to install my bathroom faucet :)
Many, many thanks!!
Very helpful. Good explanation.
Good work! It's a great feeling when you do a better job that the "pro" 👍🏻
Using that little flexible Fernco coupler indoor is a violation of code in many (if not all) parts of the US. What happens under your vanity is that your contractor used the wrong trap/marvel adapter (1-1/2'') and hence the wrong p trap. 1-1/2'' pipes are intended for kitchen not the bathroom. What you want to do is to replace the trap/marvel adapter with correct size (schedule 40 1-1/2'' to 1-1/4'') and then install a 1-1/4'' p trap
I looked that up and the 1 1/2 side is slip with no threads. You can see that his hookup has threads. I would be nice to have a reducer that had threads on both sides.
You have to glue the 1-1/2” side and the 1-1/4 side is threaded
Good video thank you
Thank you so much!
LOVE THIS VIDEO
Thank you
Thank you!
A trap adapter would do better job and more safe for future leaking. Also your drain 1-1/4 is way to short it should go all way down to the bottom of the larger part of the P trap ( socket ) that’s why is it made like that. Good luck and hope you get no leaks soon or a clogging.
Thanks buddy!
This is why I came here I have that problem thanks very helpful video
Thank you.
Thank you sir
Good job bro. You just saved me some time.
I was going insane thank you
Sewer lines are low pressure lines and therefore DIYers can be creative when doing plumbing jobs. Obviously companies know this and are making these adapters to connect the creativities together, lol. Plumbing on supply lines is a whole new world...
Nah it’s fairly simple when you know how to work pex. Plumbing is now total diy job regardless of what actual plumbers think.
Thanks
Thank you! I'm trying to install a sink on my own and I could not figure out how to fix this issue.
Washer reducer. Thank you!
Thanks for the valuable info my contractor was a narcissistic he talked a good game , but his work demonstrated he didn't know much of anything. Bootleg. Thanks
THANK YOU SO MUCH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thanks ❤❤❤❤
Why do you have a kitchen faucet in a bathroom? And why did you connect you p trap backwards
Thank you I've been trying to figure my sunk
Now days there are a lot of School Contractors, people that didn't have a residential maintenance background and went to school to get their contractor license but have zero experience working on the field, struggling, trying to figure things out...OR you have the other group, the ones that have 20 years experience and still suck.
great video. can you post the link for the reducer washer, thank you in advance
Sure, there are a couple sold on Amazon. I will list all of them here.
The one sold and shipped by Amazon, made by Keeny, a large manufacturer of plumbing supplies amzn.to/3pug3JF
Here is the same product sold by a 3rd party but fulfilled by Amazon: amzn.to/3GaGXMP
Here is one sold and shipped by a 3rd party, made by Keeny and has the chrome nut amzn.to/3pudFmu
Hi, where did you get this vanity? Thanks!
Menards
Just bought a new faucet for my bathroom. Old faucet had a 1.5" tailpipe while the new faucet has a 1.25" tailpipe.
Hope this video helped you.
What keeps the the washer from being pulled off away from the sink if something were to bump underneath?
Yeah, I've got this problem and I'm wondering the same thing. The washer is the only thing holding the tail pipe extension, which will slip off pretty easily if pulled
@@chockey134 I talked to a plumber friend and that's just how they are. Doesn't make much sense but oh well. I just did 3 of them on my new vanities. Just get it tight as you can without breaking anything and they'll stay pretty snug once everything is finished
@@johnwayne7595
Thanks
I'm going to try one of these and see if it's more robust:
GENOVA 700 72311 Trap Adapter, 1-1/2 x 1-1/4 x 1-1/2 in, Spigot x Slip-Jamnut, PVC, White, SCH 40 Schedule
@@chockey134 id say you'll be just fine. It's hard not to overthink stuff like that cuz nobody wants to deal with problems down the road.
This guy needed an extension for the tailpiece. Even without being pulled, it could pop off on its own the way he made the connection.
You can also just use a complete 1 1/4" P-trap and buy a reducing Slip Joint Nut with Washer which attaches at the WALL, instead of using an entire 1 1/2" P trap. There are a bunch of ways to accomplish this task, but yes, your contractor is misinformed LOL
Is that a kitchen faucet?
Thank you I bought a house where they installed a new sink and vanity and did not connect the sink drain
The issue can be this: when hiring or using a contractor, just b/c they have a GC license or are a registered contractor; doesn’t make them automatically an electrician, plumber, tile guy, mason, etc…. And most contractors will do framing and “wood work” and sub out the plumbing, electrical, tile, and so on. IMO, you definitely 100% want to get a Trim Carpenter in for final work after a whole home remodel, or depending on rooms remodeling…..having a trim Carpenter can make a HUGE DIFFERENCE in final results and those DETAILS that make a job AWESOME, instead of ok, IMO.
感谢国人！我的plmubing issue终于有救了！
i noticed when i tighten the reducer waster to tight it goes through the compresison fitting
Um the p trap at lowes comes with a reducer washer i hope it works.
How can you trust someone who makes a video using the P-trap backwards?
He is not stupid he has to do it by code that is 100% not code
Long story short get a REDUCER Washer set.....LOL
Using a kitchen faucet in your bathroom? 😂
This video could've been 2 minutes long if he didn't repeat so much and dissing his cheap handyman he was trying to hire.
My only question is what is a p pipe
he means p trap,
He doesn’t understand, plumbing to code.
Just always dry fit. If U don’t know, 1- add your ptrap measure your cuts (1 1/4” insert usually)
2- remove p trap to install extension arms and add back again as last fitting.
3-Teflon tape, clockwise, (same direction ascoupling is tightened) & never above first thread.
4-Don’t over tighten: hand tight then 1-3 wrench turns. Follows basic, U should be all good 👍
I only dislike this because there's too much useless talking. Just get to the point.
You're saying almost everything backwards... 1 1/2 is used in the kitchen. 1 1/4 is common in bathroom.
The trap is backwards
That's why his tail piece is too short. He's not even a good handyman plumber.
Well guess what if you took the old trap off of the inch and a quarter tailpiece you would have that inch and a quarter inch and a half washer and someone already said that the trap is hooked up backwards. That's why you're not a plumber but can't see it from my house and that's going to leak. By the way, you got too much attention on it 😜
Maybe you should have rehearsed before making the video. Totally disorganized and scattered.
00:39 ummmm, what you are holding is not 1 1/2", it is 1 1/4"
Yeah no. This was way too confusing.
What was his name. He can't be very knowledgeable
Dude, you have to work on the lip smacking.
If you already had a 1-1/4” tail piece, why didn’t you just use a 1-1/4” p trap? You’d get a better fit.
because the supply line was 1 and 1/2 so there would be an issue down lower in that case. you can fix the issue higher or lower but its probably best above the p trap due to lower pressure. But I don't think this washer is the safest. An adapter would be better
This guy knows very little about plumbing.
F commercials
Painful to watch.
I can’t even make it through the end of the video between the random rambling and terrible shots coming in and out of focus. Jesus Christ.
This guy likes to talk could have explained it in 2 minutes. He is the type of guy that would take 10 minutes to tell you that it is daytime
Thank you so so much!
Thank you
