Hello all you DIY Sages!

I've just dug all the central heating pipes out of my concrete floors in my
bungalow ~ the joints were not protected from the cement & were leaking all
over the place. I now need to replace them all & was wondering whether or
not to use plastic pipes & pushfit connections.

Obviously they won't suffer the same fate as soldered copper joints but how
do they compare with respect to their performance & reliability?

In the real world you should be OK burying PB or PEX (Hep2O etc or
Speedfit) directly in your floor, but the BS (rather bolting the stable
door IMO) says that you should install them so that they can be removed
and replaced (without digging up the floor) later. For that purpose you
can buy corrugated plastic pipe (like the stuff used behind sinks and
baths for overflow, but a bit bigger) from BES etc (you run your Hep2O
etc in it)


Sounds like the BSI committee was loaded from people from the CDA?
