I could do with a clue on pipe freezing too, would be considerably
easier than drain the whole thing down. Presumably I'd need to
freeze
both the rad pipes, and I'm guessing the quoted upto 35 minutes
means
15-20 IRL.

When I used pipe freezer, my main probem was the time it took to thaw
out
before I could try the stopcock I had fitted. It is important that
you only
freeze a straight run of pipe and that you make sure that the ice
plug is
long enough.

that sounds like a problem then... on 2 of the rads I've got just 4" or
so of riser to play with, and thats what I need to cut to put valves
in.

That also leaves the q of the best way to cut the pipes: some of
them
are up against the wall, making a hand held rotating wheel thingy
un-fittable-in-there.

There are compact pipe cutters, which only need as much room behind a
pipe
as given by a normal pipe clip.

I dont have that on one of them, the pipes against the wall. :/ Angle
grinder it is I think. Hacksaws not going to be practical here - but
nors the mess created by an angle job.


Thanks Colin.
