I'm going to borrow another pressure gauge just to be sure I don't
have dodgy equipment! Will also call the waterco to see what they
have to say.

They'll tell you to turn the pressure down by partially closing the
stoptap, which is what you should have done before buying a regulator.

Why on earth would they say that? It won't make any difference to the
static pressure.

.....or is there a pressure regulator at the exterior stop tap tap? (I find
that hard to believe)
