I rarely get beaten by DIY jobs, but it's looking like this one may get
the better of me.
I'm trying to get the crosshead top off a tap, the sort with a screw in
the side of the head. The screw came out easily but I can't budge the
tap head. I've tried making wedges and tapping them between the head and
the body, and I've tried hot water over the head, but no success.
Annoyingly I can't even budge the nut securing the tap to the basin, so
I can't take the tap to the workbench.
Any ideas?

There's a slight crack in the Twyfords Ceramant basin (which I think was
fitted when the house was built in the 1930s) so maybe it's time to look
for a replacement :-(
