If you fail with whatever washers or mechanical fixes you try, the gunk

Thanks for that.

Is this a "hot" water tap, or a "boiling" water one? Just thinking what
liability issues there could be if it *really* lets go and scalds someone?

Its a hot water as in hot washing up water. So at the moment they are
messing around with kettles for the washing up water (not good).

The previous hot water system a decade back was a lethal uninsulated
wall mounted stainless steel cylinder full of boiling water with a tap
that would drip scalding water from time to time over the sink.

It was great for making tea in bulk but seriously dangerous to have bulk
hot water on tap with a lot of exposed metal at ~100C.
