Good question. I think jet pumps are mostly metal, but then how much are they going to go through every tank, hose, fitting, valve, etc and demand that every piece of plastic be stamped "food safe?" PVC pipe isn't "food safe," even though most of us are drinking water that was piped through it. They are going to have to ease up a lot on the plastics restrictions to make organic hydro realistic on a commercial scale.
