Tested it tonight
No leaks anywhere with hose pipe in sink
Filled both bowls and pulled plugs at same time, leaked from both waste connections under ceramics.
No mastic or sealant on anything yet so pleasantly surprised
No leaks on pipework at top or at bottom where nc alpine universal just nipped on ikea European size and 40 mm solvent at other side
Solvent goes into reducer 40 to 50 mm solvent , no solvent used yet on that connection
Rest of it is about 5 mts of 50 mm into drain
