I’m hoping someone may be able to point me in the right direction when it comes to connecting a new toilet to the existing soil stack. Hopefully, to avoid any future problems and potentially smelly repair jobs! I am putting a new toilet upstairs at the opposite side of the house to the current one, but want to go into the same soil stack. In order to avoid the two pipes meeting at the same point and to avoid some other pipes I need to drop one branch down by about 300mm. Can I do this using a 125deg bend or would this be bad practice? Am I better going down vertical then across? I’ve attached a diagram which hopefully explains a bit better (apologies for the terrible drawing!) Any advice would be greatly appreciated!
