I think it was 'on site story', and they were laying underfloor heating
pipes. I was interested to note that the plastic pipe was formable, i.e. the
guy bend it round his foot and it stayed there!
After just plumbing in my new hot and cold water tanks with 22mm speedfit
pipe I realise the benefits of the pipe staying where you put it. Don't get
me wrong, I found speedfit superb for getting through the tight confines of
my loft without having to bend and rebend copper, and despite the worries of
some traditional plumbers, I love the connectors too. But moldable pipe -
that would have been better. The speedfit has 'memory' in that it wants to
return to the coil it came in - and you end up wrestling it.

Anyone know what this plastic pipe is? Is it only for underfloor?
I have CH to fit next year, and it's worth me knowing.

TIA
