Looks like the bit in the sink (plughole) is screwed into the bit below and this seems to have snapped completely.
No problem, I thought, got replacement from screwfix. Fits well - apart from a side waste flex pipe. Seems this one is slightly smaller diameter than the one thats currently there.
Of course, I could replace the entire flex pipe (but I cant get up behind the sink to do this) with the new one in the new kit.
The washer from the old fitting wont fit into the new waste and new washer wont fit around the old flex pipe.
Whats best plan here? Find a washer that fits or something like wrap with tape?
