Just fitted new washbasin in the bathroom. I have screwed in the waste
fitting and connected up the waste pipes. All looks ok, until I turn the
tap on.... it appears as though as soon as the over-flow chamber gets
full (as the chrome plug /basin seal is obviously not water tight and
water leaks into the overflow chamber surrounding the plug hole fitting
even at low flow) the seal where the waste screws starts to leak. It
appears as though the large rubber washer between the waste screw and
nut isn't doing its job. HELP !!
I have tried all variations on tightness of this screw fitting but with
no luck. Any tips ?? What am I doing wrong ?!
Try using silicone (Fernox LS-X is good) or maybe plumbers mait.
Some suggest ditching the washer entirely and just silicone it, I
usually leave the washer and silicone both sides of it myself though,
seems to work well enough.
Remember to give the silicone time to set before putting water down the
Lift the whole waste outlet back out of the sink and smear some sealant
around the underside of the grating section. Lay it back in the hole but
don't squeeze it down.
Take the rubber washer and look at both sides of it. One side should have
ribs running around it and the other side should be smooth.
Smear some sealant around the ribbed side and place it over the tail of the
grating with the sealant on the upper side toward the basin.
Put the nut on the tail and, holding the grating gently with one hand, start
to tighten the nut on to the tail.
When the washer touches the basin, press down gently on the grating and then
line it up with the centre of the hole before tightening the whole thing up.
Don't use any wrenches on the fitting at all, as these waste outlets are
best just taken to hand tightness and no more. Then leave the whole lot for
a couple of hours, until the surface of the sealant has skinned over, before
running water through it.
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?
Had the same problem myself.
Did the smear of silicone under the waste itself and then reassembled
all the bits with ptfe tape on every thread whether it looked to need
it or not and not leaked since. :-)

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 impe
rfect then the sink slowly empties. If the bottom seal is imperfect then th
ere'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 b
etween the nut and the waste. A couple of dozen turns of PTFE tape round th
e thread on the waste fixed mine.
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.
What do you say PlusNet customer whitehouse66.pndsl.co.uk
I just did the same, and had the same problem.
The rubber washer was profiled and not symmetrical, but no hint
which way round it went. I took it apart and turned it the other
way up, and that fixed it.
Mine came with a foam washer for this purpose, which squashes
to just about nothing when you fit it. Without that, the sink
would slowly empty when the plug was in.
