Plumbing, Barrier Plastic Pipe Advice:
 

Advice needed on plastic pipe. Being Old School I have always used copper pipe. I am replumbing our house to get rid of the old lead pipe and connect up the extension. Plastic pipe appears to be "the future":) Toolstation sell JG Speedfit and a cheaper make. Is it best to use the Speedfit or is the other O/K? Also what is the difference between the PEX and PB Barrier pipe? Your advice would be greatly appreciated.

used the speedfit, for the first time a few years back, old school as well. Brother had been using it for a while and swore it was the future. Fantastic.

Don't forget the inserts for your joints. buy a cutting tool for a quick clean cut. small water leaks do a lot of damage. so don't skimp on low cost.

make sure you remember where you put the pipes, wouldn't want to drill through them at a later date!

The difference between pex and pb is basically how it's made and it's properties, have a little read of this

I'd go for the better quality pipe like the JG stuff, a Tim says don't forget the inserts and make sure they're the right inserts for the pipe and fitting. E.g john guest has 2 types of insert the superseal and standard. The superseal is only to be used in JG push fittings but if you're connecting a compression fitting to the pipe you need standard insert and copper olive in the fitting as the brass ones are too hard. Also with the JG ones make sure you tighten them once the pipe is fully in otherwise they will leak at some point.

Jg fan hear. Used in boilier feed after 2 meters of copper too.
Decorating behind the radiator is a breeze as the joints rotate :), just unscrew and twist.
They don't work on chrome pipe. That's about it.

Re: Plumbing, Barrier Plastic Pipe Advice:
 

I generally use polyplumb or hep2o stuff

None of the push fit works on chrome pipe.

Re: Plumbing, Barrier Plastic Pipe Advice:
 

Screwfix is the easiest way to pick it up. And they always have J&S in stock round hear.
Just checked and they do the polly pipe too!

Thanks everybody for the replies.

They won't be doing poly pipe for much longer, was in there the other day and speaking to the manager he told me that they're stopping it soon.

I get mine from my local trade merchants

just had the house rebuilt more or less and almost all are JG stuff. Cant fault it. My builder swears by the stuff.
