nope. and its not on the diagram so I haven't just lost it ! If you think
about it, you dont need one as the chamber around waste beneath the grill
is designed to fill with water when the sink overflow has to kick in.



I don't accept that!

If the flange of the waste fitting doesn't seal to the basin, what stops the
water running out - by seeping round the flange into the chamber you
mention - when the plug is in?

Having done this job a few days ago:-

In theory the waste should seal above and below the basin. If the overflow drains into the chamber below the plug, then having a perfect upper seal is less important than having a good seal underneath. If the top seal is imperfect then the sink slowly empties. If the bottom seal is imperfect then there's water all over the floor.

I found that the rubber seal sealed well between the nut and the underside of the basin (a B&Q cheap basin) but water was leaking through the thread between the nut and the waste. A couple of dozen turns of PTFE tape round the thread on the waste fixed mine.

- Yes the thread is an important thing to seal.(In this case)

Our new friend Mr WhitehouseFB seems to have tagged onto this old
thread in order to rubbish a camping equipment company.

The OP was just about a normal bathroom sink and no mention at all of
camping in the thread until now.

%Profound_observation%

As the slots for the overflow may well be above the bottom of the chamber
there will be some water left behind which would leak out past the threads.
