Hi all,
I've just started the above ground discharge section of my level 2 NVQ and am confused by soil stacks and branch connections (the text book doesn't give nearly enough info, just two bad diagrammes).
I've tried searching the forums but no luck.
My issue is with branch connections into soil stacks and cross flow.
According to the building regs part H page 8 - The ways to prevent cross flow are:
- Have connections at the same level but coming in at least at right angles to each other when looked at from above.
- Have the connections offset with regards to the height they enter the stack (variable distance based on stack diameter and what the branches serve).
- Create a parallel junction of at least 50mm so that the branch connects outside the no connection zone
My questions are therefore:
Are there other methods?
How does the angle that the pipe enters the stack at affect things?
Thanks in advance.
