Help with soil pipes

[CPdiyer]

Hi
I Have a soil stack and I would like to move it 2m to the right, however connecting underground will be a nightmare - is it possible to have a stack 2m to the right that run into the original assuming I am using the correct falls and connections? Would I be breaking regs?

 

[Ian H]

I would say it will work but no clue on regs. I worked on a house the other day and the stack was like a water slide but worked fine.

It will be ok but ugly. Is it just a vent or is it servicing a loo etc?

Photo and sketch over where you want to move it to would help, also identifying all connections.

Often moving the stack is no the problem in itself - it's all the stuff connected to the stack.

Not sure exactly why you need to move the stack but the wet part of the svp should be vertical with no offsets.
The svp above the highest branch entry can have offsets ( usually around the eaves gutter ) ,and you can have a horizontal branch from a wc to the svp of course.

Soil pipes can have bends and branches wherever they need them. All one is required to do is ensure that there are means to clear blockages, should one need to.

 

[Leofric]

Building Regulations approved document H1 - Discharge stacks , clause 1.27 states offsets in the 'wet' portion of the stack should be avoided.
It adds that if unavoidable then in buildings not more than 3 storeys there should be no branch connection within 750mm of the offset.

Approved document is mostly examples, i would say in the context of drainage bends should be avoided full stop, don't just put them there for fun! The no connections within 750 is because high speed poo will make a mess and fill up any adjacent branch connections if it's colliding with a 90 degree elbow.

Your right or my right?

You're really stretching my Korean now.

Might have missed something but going back to the original question why is it necessary to move the soil stack 2m and have any of the replies helped ?
