Copper Y fitting and cabinet install


I am ready to install a new kitchen cabinet but the 2" diameter copper sink waste line coming from the wall has a 'y' fitting on the end of it. I'm not really wanting to cut a hole in the back of the cabinets that is large enough to fit over the 'y' fitting.

Once countertops are installed we plan to have a professional plumber come back in and install the water lines and hook the waste lines back up.

Question is: What would be the best method for removing this fitting prior to installing the cabinet? 1.) Sawzall and cut it right at the edge of the fitting? 2.) Heat and use channel locks to loosen the fitting? 3.) Something else I hadn't thought of?

There is approximately 2.25" of pipe extending from the wall before the fitting. Once the cabinets are installed the will encompass 0.75". Is 1.5" of pipe protruding from the back of the cabinet sufficient for a plumber to connect a waste line?

Any assistance is greatly appreciated! Thank you in advance for your help!

I'd heat it up and pull it if possible. But he should be able to connect to 1.5" as well. As a side note, double check your stub elevation. If your new sink is deeper or your adding a disposal, your stub out may be to high now. Easier to lower before the cabinet goes in.

It pulled off cleanly after about 1 minute of heat. Guess I shouldn't have been so gun shy about it. Thank you for the assistance!

I hope you listened to the E-Plumber about the elevation-----Under mount sinks --extra deep with a garbage disposer often need a lower opening than in the old days.--Mike---

Also just one more thought : What kind of shape is the copper in? If it looks deteriorated, you might want to have him come BEFORE the cabinet goes in, and replace the part of the line that's inside of the wall.
