Joints are childsplay (Speedfit is made by a toy maker). In most cases you
push in the pipe and that is it. There are brass and copper pushfit fitting
for copper pipe. This is the better pushfit method. Copper pipe does not
sag when hot. Plastic is better suited for cold supplies.
I have not noticed any real difference.
Some has been around for 20 years, but fitting design changes by the year
(If my memory is correct, Hepworth are in their 3rd re-design), so not
proven. Copper will not deteriorate if treated correctly.
