m I right that this is an early HEP2O type of barrier pipe?
Probably polybutylene, HEP20 was the major brand but there were other
manufacturers.

Last time I used Hep2O was about 2000 and there were 2 types: barrier for
CH and non-barrier for water supplies.
This might have changed by now - looks as if all Speedfit is barrier.
