200mm Waste Pipe

[Ryan Bazeley]

Can someone please help me?

 

The waste pipes that are cast in my slab out to the sewer pipe are 110mm. I have noticed on my plans that BC have stated I should use a 200mm pipe! I will have 3 bathrooms which will all drain into the one stack, would that be the reason they say 200mm? I can change it if necessary but do I need to?

 

Thanks

IGNORE THIS, I AM AN IDIOT!! It was a 200mm radius bend ?

In case it helps... you should put larges radius "rest" bends at the bottom of stacks.
