Want to pick your brains. Having a extension done on the kitchen and wife wants to swap the living room and kitchen around so that living room faces the garden.


Soil stack currently in corner of kitchen and can't be moved as all services are at rear of house. From the soil stack to where the sink would be is just under 4 meters.


Ground floor is all concrete, 60s house and would need to dig a Chanel from stack into the new kitchen location. Would I get away with doing the waste in 2"? Would be in a straight line from stack to new kitchen just under 4 meters and would need to feed sink, washing machine and dishwasher.


Thoughts?
 
Technically the maximum length you can go for 50mm is 4m for multiple appliances discharged into the discharge pipework branch. Lowest connection point to the stack must also be 450mm above the invert of the drain. Download part H from the goverment planning portal for more info.
Make sure you take precautions to stop it being crushed or damaged and think how you will tackle a blockage for access. Ensure you allow for sufficient fall and that connected services are sufficiently trapped.
