I am having a real problem fitting a new waste to a new small basin.The
waste is the one with a slot in the side for the overflow.Problem is try as
I might it leaks. I have fitted it with plumbers mate under the plug hole
end and then between the rubber washer and the sink underneath so the large
nut squeezes the putty into the gap.In fact I have remade this about 6 times
so far and it either drips when empying or trickles when overflow tested.
What am I doing wrong?
I tried the washers given with the waste which were a flimsy white one for
the top and a sturdy black one for the bottom and they didnt work so the
supplier said use pumber mate instead.
Any suggestions gratefully received.
First of all check that the large nut is tight enough.
You need a tool to tighten this, hand tight is not good enough.
If that does not do it then take off the rubber washer and clean off all the
sealant from the washer and the basin. buy a polythene waste washer( a few
pence) and put it between the large nut and the rubber washer.
What often happens is the friction of the big nut tightening against the
rubber twists and distorts it, especially if the rubber washer is on the
Yes, that is what I mean. But, don't forget to use a poly washer as well.
If I was doing the job then I would do away with the rubber washer and use
only the poly washer. I would then use plumbers mait or silicon sealer
between the washer & basin.
You're not necessarily doing anything wrong. Plumbers Mait doesn't work in
all circumstances and there is a certain amount of controversy as to it's
long term effects when in contact with plastic.
I had exactly the same problem. A good clean, making sure all contact parts
are dry and an application of silicone sealant in the appropriate places did
the trick first try for me. Hope it does for you also.
