I spent about 7 hours of yesterday removing a two tub kitchen sink and installing a single tub kitchen sink. I did a lot of Amazon shopping and made the final decision 2 times before finding another one that I liked better. I had a tall faucet that I bought a year ago just because it was on sale, so that will replace the single handle Delta that I have disliked since day one. (difficulty making an adjustment for comfortably hot water.) All went smoothly, only one trip to the hardware store. I did have to unsolder a 22-1/2* elbow from the 1.635" OD copper drain pipe sticking out of the wall, this pipe is about 0.06" larger than the hole in the threaded compression nut, so I had to sand the nut larger to fit and then the plastic washer had to be stretched to fit the pipe. I don't know if there is an actual piece made for this transition, but I made the standard parts work. The drain leaked on the initial drain, but after tightening one pipe fitting, that was fixed. (Too many people helping under the sink
It was not the one I made kluge fix for.
On removing the 22-1/2" elbow, I had a Mapp Gas tank, I think that helped get the elbow off with little trouble. Propane at a cooler temp would have had more trouble on that large amount of copper.
Now, will we ever use the drop in cutting board or the drop in drain rack, or the drop in vegetables cleaning tray. Time will tell
But, it sure is easier to wash larger pans and the wok in the single tub sink.
In a couple years, I get to take it out and put in new counter tops. The wife was content not doing it now, when I said lets wait until we start collecting SS in two years and hopefully by then we will have gotten back some of our stock market losses and our son will have bought a home. I left some outs for two years from now. Besides, vintage is good!
