Hello
I am working out a new kitchen for someone who wants me to move the location of the sink. In its new position, the sink waste will need to turn 90' (L-shaped kitchen), but more importantly, its probably 4500mm from the stack. Gradient shouldn't be an issue as I am planning to fit an IKEA kitchen and run the waste pipe in a false compartment behind the Faktum units. The questions I would appreciate any thoughts on are:
a) That 4500mm-odd waste pipe run. I know the normal max is 3000mm - what options are there for me - I have heard people talk about putting a 40mm pipe into a 50mm pipe and also an anti-syphonic valve. There is no scope to put an air admittance valve in or a different waste stack as this is a first floor flat, concrete slab floors.
b) 90' turn in a waste pipe. Not great, I'm presuming? How much of an issue is this likely to be?
Other than not moving the sink as requested, I'm racking my brains to any other solutions to this. What would I need to worry about if I just ran the pipe from the U bend for 4500mm with a 90' turn?
Sorry for the naive post, this stuff is quite new to me.
