I've bought a monobloc tap that came with a pop-up mechanism. This was to be fitted to a basin that sits on top of (not part recessed into) a granite countertop. The basin has an internal overflow so the waste has to be slotted.
The problem is that the top half of the waste only reaches part way through the basin and countertop, and the bottom half can't meet it up the way because the branch for the pop-up mechanism sticks out too far to fit through the countertop hole.
I guess there are different types of waste so I'm not too surprised that this doesn't work, but my problem is that I can't find any other sort that is made for this situation. It's not anything unusual: a basin sitting on a coutertop.
The only solution that comes to mind is to buy a cheap plastic waste and cut a section of the tube to act as an extension. I just think that tere must be a genuine item available.
Help!
