> Our water was tested years ago by the waterboard and came back way below the legal limit. Where was the water tested? I've heard that here in France, water is often tested before going into the pipes, and not after flowing for the faucet. If that's the case for you too, I'd encourage you to test the water going out of the faucet, since this is the water you actually drink. In France we can do that at labs that take care of stuff like blood samples. A naive search gave me this website https://watersafetestkits.co.uk/which-water-test-kit/ https://watersafetestkits.co.uk/which-water-test-kit/ that sells water test kits, for example.
