As a newbie DIYer I've been going round the house installing TRVs in place of the old manual radiator valves. Everything went okay upstairs where there are floorboards and plenty of movement in the pipes but I've run into a snag downstairs where the pipes go straight into the concrete floor.
The new TRVs sit 3-4mm higher on the pipe than the old valves and don't line up with the radiator tails so I've come to the conclusion that I need to trim a bit off the end of the pipe. The question is, what's the best way to do it? I don't think I can cut it off with a hacksaw or pipe-cutter as there is so little material to take off I think I'd just mangle the end of the pipe. In the end I have shortened one with a (very blunt) file, but it took ages and I've got four more to do. Is there some trick I'm missing or should I just invest in a better file?
Cheers
Keith
