Water pipes (Dawlish)

Tweetop PERT-AL-PERT MLCP Pipe 16mm & 25mm diameter offcuts - some quite long, over from a house build project.
Recommended for use in following types of installation:
cold/hot utility water
central heating (radiator connections)
surface heating
compressed air
ice water
technological and industrial
Currently in a dumpy bag outside but in good, clean, usable condition. Expensive to buy new. We don't have any fixings, just the pipe.
