I was refilling my kitchen soap dispenser the other day and somehow the person doing the work broke the ends of the threaded pipe that the refillable bottle connects. I did not panic, I just went to Loews to get another one. I was not surprised to find out that I could only buy a matching blackened copper finish soap dispenser if I bought a complete kitchen facet set. Arrrrgh.
So I decided to get a cheap plastic chrome replacement. Before I opened the box I read the description and it described how you could use the included tubing to bypass the refillable bottle and connect to a large liquid soap bottle. This would eliminate having to go under the sink every few weeks to refill it. Instead of keeping the cheap dispenser, I bought some 1/2 inch OD by 3/8 inch ID tubing and fitted my existing dispenser with it. I cut a 1/2 inch hole in the top of my super size Dawn bottle from Sams club and viola, it works.

I wanted to test this before installing it. It works

Blue tubing has Dawn and is going up to the bottom of the sink.
