Why, and what's the difference ?
Slotted wastes appear to have holes in the side - which i'm having trouble figuring out why you'd have them, since they would logically be liable to leak ?!?

basin waste question - slotted or solid ?

Slotted wastes are for basin with the traditional cast-in passage from the overflow.
Indeed. The top flange seals against the inside of the basin, and the bottom rubber washer and nut (plus a liberal dose of Plumbers' Mait) seal against the bottom face. Water running out of the overflow flows through the internal passage and *into* the waste via the slots - and thence on down the drain.
Thanks for the replies - makes sense now :-}
(i'll have to check out the sink we bought now, see what sort it is !)
