Hi the rubber washer on my Elddis avanti 840 has perished I was wondering if any one new the washer size and were to get one or have I got to change the whole thing thanks in advance

It could be 38 mm and on Amazon or EBay there are plenty available. But most seem to be multi buys so may just be as cheap to buy the complete pop up bit with its O ring fitted.

Here’s an EBay option:

Not quite. Click-clack plugs are not quite what they seem. The washer is not just as simple round thing but rather a ring with a 'skirt' and as such are not replaceable. The only option with this type (for example as used by Bailey) is a replacement bowl drain assembly which the last time I looked cost around £20 and are beggars to fit!
