First of all fix the trap if you can’t assemble that correctly you shouldn’t be making this video. Then put a double offset in to the trap adapter and you’re done have a nice day.

Without a doubt the best part of these videos is the comments section, where you really learn a lot. Congratulations to the videomaker for transparently exposing himself to criticism and to all the expert commentators for indicating improvements 🙂

I have an antique buffet that I put sinks in. It's beautiful but they don't line up exactly. I don't know if I can do this, but thanks to your video, I may try. If it doesn't work, My only other option is to buy a new vanity which I don't want to do. Thank you for taking the time to make this.

[pstreicher]

Well, after struggling to replace a Form-N-Fit drain pipe under this kitchen sink I now see where I need to use a 45 degree adapter to make it fit. I've learned something new again today. I love how you describe in your videos exactly everything in an easy to understand way to do things right. Thanks for all you do for us d.i.y.selfers here.

[barryrobertson]

This saved my life haha I just bought a house and the downstairs sink had a way offset like this and the previous owners had one of those flexable plumbing pipes and its leaking so I was sitting there racking my brain trying to figure out how to fix this mess they had going on. Perfect solution. Still have to play around with it a bit because the offset is actually a bit farther than this but this definitely helped me out and gave me a couple ideas

[lisasocal]

Thank you so much! This is the first time I’m changing a very old faucet and the pipes didn’t line up. Home Depot sold me the snappy trap, but it didn’t feel right to use as I was putting it together and then I found you to confirm my thoughts! I’m off to HD now to return it and get the proper supplies. The info you shared was invaluable, thank you!

[renedecroce]

Thank you. You were very clear and walked through each step clear and concisely. This is going to be my first sink hook-up. Bought an off set sink and have to hook it up to the line coming out of the wall which is off to one side.

[JustSayNO]

I had a similar condition and used Oatey's "1-1/4 in. Form N Fit Flexible P-Trap". I've had this arrangement now for 13 years and there has been no cracks, leaks, or disconnects. I could have achieved the same result using multiple fittings like Jeff demonstrated, but this was my residence, not a client's.
Now a short message to all those who have criticized Jeff on this channel. There's a reason why he has over half a million subscribers and his videos rack up millions of views each. When you (who criticize Jeff) achieve these same results, then you are qualified to judge Jeff. Until then, keep it cordial and offer your advice in a kind and considerate manner, like I have done.

I thought the quality for a novice DIYer was spot on! Thank you so much for the thorough explanation and overviews as you progressed through the project! I successfully redid the plumbing on my new vanity using a 22.5 deg elbow.

[salazteca]

Wow there is always the right way to do things instead of the fast and easy way, I almost install one of those stupid flexible adapters.
Thank you Sir You just save me lots of future headaches

[Invasion]

I had this problem with a new vanity. I love the solution. One suggestion: save time with video editing. I realize that it's not incumbent on the teacher to go thru extra steps but these are made for DIY folk like me and we will watch the video more than twice. THANK YOU!

[tcurr]

Paper towel test saved me a mess Jeff. Good pace of instructions 👌. I recommend these videos. Thanks

[DoniaDesautels]

It's 2024, I'm doing a remodel on my kitchen (on my own), and just came across this problem, except I'm using all 1.5" PVC, so I'll have to figure that out. Thanks to you, I now know how to fix it, of course, after I read all the drama comments haha!! Thank you!

[jsubound]

Dr. Umar is a blessing with a hell of a lot of patience and his level of patience is displayed throughout this entire interview. Ole boy didn’t want to hear anything from the jump. He wanted to be combative and had a rebuttal for every statement from Umar even before the statement was given.

[m.jamesabernathy]

I am a complete novice and I was very impressed with your knowledge and now I need to try to do this myself. I think I can. I will let you know.

[mark]

Nice work! I’d like to share that those hand tight p trap fittings have been my nemesis on more than one sink. And I’ve learned that the fittings need to be plumb and level or they will leak. Appreciate you sharing that the tail piece extension should run well past the connection. I’d probably square and smooth off the end of that short stub of 1.5” PVC pipe added. Other than that, looked perfect to me. Thanks for sharing.

[charliel.]

Thank you. I appreciate how you explain your work. I love it when people tell you why. So many instructors just tell you how to do it but never explain why.

[mwilliamson]

So helpful ❤thank you. My daughter had the accordion type of thing that just failed under her sink and I sent her your video on how that is not code. And this one on how to fix it properly. ❤ hopefully she will get it done right now. She’s had to correct a lot of issues with her old house and I’m in the same boat. We’ve both been learning a lot. I appreciate doing things correctly. It’s not only correct but safer and this home isn’t my forever home, I’m hoping to sell eventually and I want it to pass inspection. But in the meantime I want each fix to last and protect my home and my health.

[candudaddy]

Glad to see that you corrected the assembly of the P trap. In the first few minutes the
J bend is assembled backwards, throwing off the vertical alignment. Later in the video the P trap is correctly assembled.

[markchristman]

Very precise! Had a heck of a time with a remodel vanity at my house. Finally put 5 to 6 wraps of teflon tape on p trap connections to stop the leak. Glad you said run water for 10 minutes because a lot of plumbers assume it won't leak. Thats the reason so many cabinet bottoms rot out.
