Have you soldered before
Yes I have I'm into Arduino's and robotics. Im also aware of how to prepare a copper pipe and how to join them using solder and osmoses. If i;ve got the correct term, i.e allowing the solder to be sucked up into the joint by itself.
I'd probably do a test piece first and put it under some sort of pressure to check for leaks in my method but other than that I don't see it being as much of a problem as say not flooding the house (i.e correctly draining the system or leaving a bleed valve open on refiling).
