Hi Group,

Wonder if anyone could point me to the manufacturer or supplier of Basin
Waste units that are Less than the standard size. My friend bought a
sink
back over from Mexico, but without any bits for it as he thought that he
would be able to get the bits here. But I have checked the dimensions of
a
standard waste unit similar to those supplied by Screwfix, item code
D66389-72, D16378-72 and D12052-72, they are all 41.5mm using a
callipers to
measure the stem of the waste unit.

Shouldn't all be the same size. 16378 is a sink waste, 1 1/2" BSP thread
whereas 66389 and 12052 are basin wastes, 1 1/4" BSP thread.
Basins are usually plumbed using 32mm pipe (1 1/4" waste), Sinks with 40mm
(1 1/2" waste).

Hi John,

My mistake should have been product D14684-72 and not the D16378 which is a
sink waste as you pointed out. I have plumbed in the standard sinks as
described by yourself too, with no difficulties, but the Mexican basin has a
smaller diameter waste hole than the standard UK basin waste hole which
comfortably accepts the 1 1/4" basin waste unit from any plumbers merchant,
but that's the point, the fitting "nut" is larger than the 32mm PVC pipe to
fit onto the waste unit threads which is 1 5/8" in diameter, I cannot get
the waste unit into the hole in the bottom of the Mexican waste hole as it
is to small to accommodate the standard size waste units as supplied by
Screwfix. So while the 32mm PVC pipe will fit through the hole in the
Mexican sink with lost of room it is not a waste unit, and the 40mm PVC pipe
is just that bit to wide also but again is not a waste unit. My friend wants
a waste unit to be installed into the sink so he can put a plug in it.

Hope this clarifies my issue better than my previous post

Regards

Glenn
