My plug got stuck due to sand, and it wouldn't budge, so I removed the waste in order to replace it.
I found the waste hole in the ceramic sink had about 1cm of silicone all the way to below the sink, i.e. around the threaded pipe all the way down. I only discovered this after I'd hacked about to remove the old waste, so I now need to know whether I should try to remove it all and fit a wider waste, or if the sink is a weird design I need a whole new sink.
Hopefully these pics will explain better than my words!
