hand basin overflow

[lordoncall]

Can anyone please help? I am trying to install the plug and waste pipe for a hand basin with an overflow. It is one of those plug sets which you push to open or close the plug. It has slots in the body of the plug set to allow the overflow to escape. It now seems that the unit is dripping from the threads where the nut screws up onto the wash basin. Can antone tell me the correct way to install this plugset? Many thanks.

Silly question but do you have the rubber washer/gasket between the nut and base of basin?

Yes , that's certainly in place. My evaluation of the leak is this: when the plug is in and water is in the bowl, all is well. When the plug is lifted, the water goes down the waste, also exiting from the slots provided to accept water from the basin overflow. The water does not drip from the rubber seal but from big screwed nut threads from which the water has access by virtue of the aforementioned slots in the body of the plug assembly.

It's a bit difficult to describe, but if you can imagine the standard plug assembly for a hand basin, then imagine a wide slot cut in the assembly, about half way down (for the overflow water to go down the waste pipe) that is where the problem lies.

Pull the back-nut and rubber washer off from underneath and squirt a small bead of silicone around the plug & waste then replace the washer and nut.

and make sure its dry when you do, or you will still

get the leak
