Again, wrong materials.



Better materials in most cases...

I would have to pay to get them WRAS approved, which is not cheap.



PLA is used for food so it should be fine.

Polylactic acid doesn't throw up any hits on the WRAS approved materials
web site search engine. That means it can't be used on potable water
supplies without somebody paying to have it approved.

As is PETG.

Nor does that.

I know ABS is used for drains and such but I don't know where its used
on supply pipes, they are usually polyethylene of some sort.

PVC and ABS are normal for commercial and industrial applications.

You can also print HIPS which should be safe....

Again, no hits on the WRAS approved materials web site.
