Dear All

I was digging up some pavers around my house and managed to rupture one
of my water pipes. Problem is that it seems to be something
non-standard (in Australia anyway) and I'm having trouble finding out
what bits I can use to fix it.

The pipe is black plastic, like polypipe except thicker and stiffer.
It has
'Charlick HI-POL 3/4" B class" written on it (although that might be R
class, it's hard to tell). It's being used for mains pressure, but I
have no idea if it's actually rated for mains. It appears to have
lasted ok for 15 years or so, so I guess it must be. The previous
owner has no idea about it (or at least, that's his story...)

Has anyone seen this stuff before, maybe know what it is or some more
info about it?

Cheers
Richard
