I replaced the kitchen mixer tap, now fixed by a horshoe shaped metal
flange on a threaded rod, about 4mm and a nut on a stainless steel
sink and 25mm worktop. This fixing is strong enough to stop the whole
unit rotating on the sink top because the tap nozzle is a very stiff
to swing around when it's cold. It has a nylon seal for the base of
the nozzle.
The old tap had a threaded pillar and big nut, approx 1.5" diam which
was more secure, also the previous nozzle wasn't so stiff.


Any ideas apart from freeing up the nozzle seal by sanding it down a
bit ?

thanks
