We are remodeling the kitchen and had the radiator moved from under the sink (that's right -- under the sink) to a new location. As I understand it, our system has one major pipe with water running through it and pipes going off of this main pipe to and from the radiators and back to the main pipe. The plumber simply took the pipes that go up to and away from the radiator and turned them and ran them over to the new location, leaving them tied into the main pipe as they were originally.

We called a different plumber to hook up the radiators who told us that the pipes were too far away from where they tied into the main pipe. He said that they could not be more than six feet away -- they are currently at least 12 feet. He tells us that he will have to redo them, draining the system, etc. kaching, kaching, kaching...

It is a hot water system and we've been told it was a mono-T system. So, which plumber is right???
