Local school asked me for a sample of my water for use in their labs to test purity as part of experiments over many water types.

They were left shocked by mine as after evaporation left zero residue. They said never before had they achieved that result.  They now want a regular supply of it.

DI only for me as I'm lucky to not to have tap readings over 70

Funny how times change.
I got expelled from school for giving them a regular supply of water. I think me peeing in the headmaster's waste paper basket for a few months did leave a residue though.
