Copper or plastic radiator tail.

[Jasontenn]

Hi,

Quick question.

I’m plumbing radiators in using plastic pipe. Should I use copper tails into the radiator valves or use plastic pipe into the valves instead.

Whatever is visible above floorboard level will be covered by chrome pipe covers so visually it is irrelevant. I’m just wondering which would be better going into the radiator valve.

Terminology note: "tails" are the things that join the valve to the radiator, and they are always metal.

I'm not aware of any reason why you shouldn't use plastic pipe into the radiator valves.

Some people think it looks horrid. I've had some where the final 8 inches or so of pipe is 10mm plastic, and the advantage is that you can neatly mould and clip the pipe exactly where you want it. I've got it clipped vertically to the skirting, so I don't have the awkward gap between the skirting and the usual copper 15mm tail. I think plastic or copper is fine - so long as you are pleased with how it looks.

A load of unsupported and sagging plastic would look terrible, of course.

I always use copper up through the floor into the valve. Much more sturdy and better against any mechanical bangs from vacuum cleaners etc.
