We fitted a new waste to the bathroom basin. It is a waste with a
slotted overflow
(http://www.diy.com/bq/product/produc...CATID=1767 38)
just below the plug hole. When water is run down the plug hole, some
passes through the slot and then seeps between the hole in the basin
and the outside of the waste pipe....wet floor. There is a seal at
the bottom of the basin but it does not seem that good a seal and
anyway it seems a bad plan to have the water seeping down there inthe
first place. There is a little bit of play between pipe and basin and
so I assume there is some (common) method sealing it.

Anyone?

There should be a large rubber or nylon washer between the bottom of the
basin and the large nut which clamps the waste in place. If this washer
doesn't provide an adequate seal, you'll have to assist it by applying some
Plumbers Mait. [You'll need to undo the nut, spread the PM on the mating
surfaces, and then do the nut up again. All should then be well].

It's also necessary to ensure that you've got a good seal between the top of
the waste and the upper surface of the basin. Otherwise, when you're
washing, with the plug in place, water will leak under the rim of the waste
into the overflow chamber.

Check. Plumbers mait is my friend on sinks

Hm, I thought the plug seal was dodgy on mine, as I have a bit of
seepage down the drain (as opposed to onto the floor). I'll have
another shufty at the waste rim.....
