we have a grohe basin which comes with a chrome S. the plumber can't work out how to get this chrome S into the 32mm waste. He showed he a push fit and a solvent weld waste and put the chrome pipe in to demonstrate they are too loose.
What should he use? See picture of sink. I presume there is some sort of boss adapter?
Thanks
