it comes with various felt/rubber washers

Would you just use the washers as supplied

OR silicon ??? the waste into the sink, the overflow etc

if silicone - what would you recommend , i tend to use CT1 - which is also an adhesive

I have read various other posts here and suggestions vary - BUT thats a post from 2004 - from use sanitary silicon, use plumbers mate & use Fernox LS-X

I will be buying some new silicon anyway - as i need to silicon in the Sink to worktop - the clips are no good and wont work

If the sink and materials are clean and of a good quality then use the Washers provided.

If that doesn't work then get yourself some CT1.

Thanks for the quick response
Sink was quite expensive on offer @b&Q less than half price (back in 2018/19) - not that thats a sign of quality i wont be able to do the overflow as i'm silicon the sink down onto worktop.
I got mcalpine as i understood those to be the better/quality fittings

If it's not done yet - if all is new then just use the fittings and seals provided - silicone should not be needed.
