1/ What are the pros and cons of using plastic barrier pipe for internal heating and H&C water?
2/ Do the water authorities allow the use of leadless solder capillary fittings on copper drinking water supplies nowadays.Dave
1/ In a word speed! Plastic piping is so quick to instal, it may not be neat and tidy but if it's hidden who cares. If it shows I always use copper, for spurring off radiators and basin taps 10mm is great as it's far easier to bend and to hide from site than 15mm. You can also get Speedfit fittings for 15 mm but to be honest they are bulky and end feed are dead easy to use with the correct prep. Look on the John Guest site for the full ranges available. 2/ I don't know but it's not something that is covered by the current English buildings regs as far as I am aware.

Thanks for that AJ
I 'm a diy man but I've done quite a lot in copper. I was hoping to do what you say, use plastic for hidden bits. I have used ordinary brass compression fittings and inserts with plastic pipe before to my garden tap. I've had no probs in 5 Winters. I feel probably wrongly that they give a stronger joint than the push on stuff and as speed is not a worry to me I'd rather use them. Are they OK in your opinion and do they fit all plastic pipe types???

You need barrier for sealed heating systems, to prevent oxygen ingress. Doesn't need to be barrier in other situations.
Yes.
