I bought a deburring tool
(http://www.screwfix.com/app/sfd/cat/pro.jsp?id=13315) and although
there's
only one way it can work - shove it in the pipe, turn - I'm not getting
satisfactory results. The tool does shave off copper, but there is
still a
burr. If I continue until there is no burr, I've removed so much
copper that
the wall at the cut end of the pipe now tapers from the inside out and is
very thin. In other words the tool removes the 'good' wall of the pipe as
well as the burr.

I've never de-burred pipe after using a wheel cutter. No leaks yet...

It closes over the end of the pipe restricting flow

By bugger all %

and leaving an edge for crud to gather.

Doesn't your magic water conditioner resolve this ?
