Most citrus aren't really lime-haters, but don't like alkaline soil.
I water mine with tapwater a lot of the time with no trouble, and
most people classify this water as hard. I don't, having lived in
South Wiltshire, but Cambridge water is definitely not soft.

Softer than limestone regions but not by all that much. My water is
fairly hard and lime haters do not do well on it.

Where my aunt lived, the water came out of the tap slightly
opaque, and an ordinary (not electric) kettle furred up beyond
functionality in a couple of months. Yes, that was on the downs,
with the chalk just below the surface.

In Cambridge, I almost never have to defur a kettle.
