Our main tap is hot softened, cold softened, cold unsoftened filtered.
The Quooker tap is boiling only and mounted away from the main tap, for
safety.

This is a hard water area and I am concerned about scale inside the
reservoir. Presumably there is an over pressure relief valve and some
sort of tundish arrangement. I don't have a huge amount of confidence
in the filter/scale remover offering either:-(

No water softener then? I think you either have to buy their softener
or have your own, otherwise it scales up.

I'm sure when I looked into them previously there was something in
manufacturer details saying they should not be used with a water
softener but couldn't find any reason why not.
