Review 1 for JG Speedfit 22BPEX-10X3L PE-X Barrier Pipe 22mmx3m Pack of 10
"Compared to copper pipe, plastic pipe is the bee's knees. It's much, much easier to use; it's cheaper (although fittings are much more expensive, and you need inserts too, so it ends up costing about the same); it hardly makes any noise when it expands and contracts; limescale doesn't deposit on it; it leaks significantly less heat even when uninsulated.
The straight pipe lengths are much easier to use than the 22mm pipe coil, which is almost impossible to straighten. In a small house like mine, there's hardly any run that's longer than three meters, so this works great. Straight 22mm pipe also comes in 6 meter lengths, but Screwfix don't seem to carry those.
The description is inaccurate, however. It refers to the Speedfit fittings, not the pipe itself. You *will* need tools: at least a plastic pipe cutter, and probably a pipe bender or a Speedfit bending spring. Use "superseal" pipe inserts when connecting with push-fit fittings, and regular inserts (without O-rings) for compression joints. You'll be amazed at how many pipe inserts you will need! Temporary joints with no lateral force work without inserts too, but that's not recommended. Also, get pipe clips -- good ones.
Beware of expansion. Plastic pipe expands more than copper pipe, so make sure long runs have room to expand, and that the pipe doesn't rub against hard, sharp or abrasive surfaces. The joints aren't able to take too much lateral force, but they can cope with small displacements."
