Hi folks. My wife and I purchased a home recently, which means I am a new DIY'er! I am about to plumb our kitchen sink. After watching videos, and reading a few too many articles I feel well prepared with one exception. I'm having trouble figuring out how to attach the proper adapter to the kitchen sink waste line that comes out of the wall.

A contractor we hired to remove/install kitchen cabinets cut off the drain pipe about ~1 inch or less from the wall. At the time, he mentioned being able to put an adapter on the pipe, and seemed like it wasn't a big deal. I never inquired further about it. The pipe is PVC, and it looks like two pipes that have been cemented together. The outside diameter is 2 3/4'', with the inside being 2''. For the new plumbing that's going in, I've purchased new 1 1/2'' PVC pipe.

My question is, how should I best approach attaching an adapter or coupling to my waste pipe in the wall? I'm having trouble identifying a good solution here. Being new to all of this, I want to make sure I get it right.

Any advice would be most appreciated. Thank you!

I am following this topic as I am interested in this forum.

Appreciate it Mike. I'll keep that in mind. I'd like to solve this on my own so I can save some money.

I'll take a picture of the pipe and post it in the thread later today. I should have done that in the first place. A picture is worth a thousand words...

Here are a couple of pictures of the waste line. Hopefully this helps better show what I'm after. I'm looking to attach some kind of adapter or coupling, and eventually a reducer, to get the pipe size down to 1 1/2" for the rest of the plumbing. The outside diameter of the pipe is 2 3/4", and the inside diameter 2 1/4".

Thanks!

The pipe size there will be the ID size.
They may pipe reamers that cut out that portion of the pipe that is glued in the hub of the fitting.
I use something like this. They come in all sizes.

Your contractor is stupid. He should of left at least 1 inch of pipe sticking out of the fitting. But he cut the pipe flush with the fitting. They do make a hub by 1 1/2 pipe rubber clamp. But u would have to cut a bigger hole around the pipe

Terry and plumber69, thanks for your input. I appreciate it.

One follow up question. I gave an incorrect measurement before. The ID is actually 2". What about the possibility using a 2" slip coupling? That would give me something to work with coming out of the waste pipe. I've tried to read a little about the idea, and I've seen mixed feedback across several forums. Probably isn't the best idea, but I wanted to float it out there anyway.

Thanks again.

They make a fitting for everything. You already have an ugly hole. Cut the hole to the right more. Take a hacksaw blade cut the pipe put a new 90 degree fitting on. If ur worried about looks. Get a nice piece of plywood. Drill a hole in it and screw it on. Cover the mess up

Just use a "socket saver" (aka Ram Bit) like Terry suggested to drill out the stub of pipe in the fitting; problem solved.

There is NOTHING that will attach to what you have there and make a proper connection. You have to remove the pipe stub from the hub before you can do anything.
