Just wondered what size waste I should use for a kitchen sink and dishwasher?
The thinner size (35mm) would be easier for me because I need to run it behind the built-in dishwasher and there is only 20mm clearance. Chasing it partially into the plaster seems straightforward enough if a bit of a pain.
It then needs to run 2.5m to the stack - how much fall should I provide?
And yes, I have examined all the alternatives and it really does have to go behind the dishwasher
