Fitting new washbasins, all 2 taphole (I got a fab ebay deal on Grohe
lever taps) - only option is with overflow and plug-chain hole.
I'd like to use click-clack wastes (push to close, push to open) - so
I need to block off the unused chain hole.
Is there a product designed for this?
If not, what will make a really neat solution?
(My only idea so far is a short, fat, stainless steel coach bolt)
