Do you have any info on safe, non-toxic plumbing? I am getting ready to plumb my house and am sorting through PVC vs. copper vs. Pex. Thx.

What to use for the piping is the specific info I am looking for, both in-house and to the house. I am in Hawaii with catchment water and likely some acid rain due to the active volcano nearby. Thank you....Jack

A good option is PEX tubing with engineered plastic fittings, such as PolyAlloy PEX Crimp Fittings, to avoid the potential corrosion over time from the more acidic water in your area.

PEX tubing can be home-run to a plastic manifold, such as a MANABLOC, so you can shut off one area at a time, to help with future maintenance.
