Cistern Coupling Washer

[Des Jennings]

I have attached a photo of a cistern coupling washer which I'm replacing with a new one shown in position 60mm I/D. Will the new washer work? It is supposed to, but there is an obvious difference in the O/D size. I positioned the cistern on the new plate and rubber washer but the cistern sits about 1cm higher than the fixing holes in the back wall. I was hoping not to have to drill the tiles. Is the older coupling washer still available?

Thanks.

Looks similar, although you have it upside down.

Thanks. The instruction for the coupling says......."so that the flat face is in contact with the plate." Have I misread it?

It's the position you have it sitting in the picture ,on the pan,that's misleading , I assumed that position was just for taking a picture ,and the washer is correctly placed if that's the case.
It will also compress and the cistern will sit lower once tightened up.

Except that the cistern does not tighten up. There are no holes in the cistern, it sits on the washer and is fixed to the back wall. The new washer raises the cistern higher than the fixing holes in the wall even when the weight of the cistern is applied. The older washer does look a lot thinner, even after years of use.

Have you fitted the plate to the bottom of the cistern? It is held in place by the syphon/flush valve.

As Andy says above ^^^
You are not assembling it correctly ,the cistern is clamped to the pan.

Thanks. I can see what the issue is now.
