I'm wondering whether there is any form of transparent plumbing pipe? I mean stuff rated for domestic water pressure that fits the standard diameters (say 15mm or 22mm). Rigid or flexible. Since you couldn't solder it, it would have to be compatible with either push fit or compression fittings. Any ideas?
