Plumbing, Barrier Plastic Pipe Advice:

[DanSp]

JG are so much easier if you ever need to remove/re-use it too as you simply pull the collar in and pipe out at the same time, the grey polyplumb is a nightmare to remove and re-use!

I use shed loads of the jg speed fit stuff, it's great for rad moves when you're going through loads of floor joists, as the alignment of your drilling doesn't have to be perfect and I'm not one of these butchers who just notch the crap out of the joists.
I've tried other brands and they are crap IMO.

As dirty dog said, never, never ever try and use it on chrome or stainless pipe, it WILL leak, don't ask me how I know.

And that's one of the reasons that I normally use the polyplumb stuff, once it's in, it's in. If it's done properly you shouldn't need to take it apart

Bet you've only done it once though

Yep

ive used both john guest speedfit and Wavin Hep2O,both work well,but i prefer the added security of h2o fitting,they still can be seperated with the right tool and are slightly less bulky,ive found that the coiled pipe needs warming up winter time to unroll and paas through joists,water from a boiled kettle poured in to the pipe seems to work,22mm is the worst for being stiff
