I am putting a new extension on to the back of my semi and re-routing the bathroom (which was attached to the back) to the centre of the house, meaning the whole back part of the house will be the kitchen.
I have at present a rather complicated rain, wastewater and sewage system with 3 inspection chambers, what I want to do is simplify this and have one single soil pipe leading 8ft to the outside of the house (into my side access), and have one single waste water pipe from the kitchen into the back garden.... I think that I will then need to connect these together to form 1 main inspection chamber at the back of the house.
To re-iterate, I want to route the bathroom pipe to the side of the house and then run that along the side to the rear, where it will then meet up with the kitchen waste pipes.
I have a diagram but cant upload it, if anyone is kindly enough to want to look and give me advice then let me know!
Thanks for your help!
