i've just picked up a new Astracast Kitchen sink at a good price
as part of general ongoing improvements. I need to buy all the 'extra
bits' separately - shiny plug'ole fittings, a waste kit, tap etc etc.
Just to check - are these sorts of parts pretty much interchangable as
regards pipe diameter, thread etc.? ie. can I expect a Franke waste
kit to fit onto an Astracast (or whatever) plughole?
