Should the soil and vent stack to a two storey dwelling connect to the head of the drain within a manhole on level invert or is it allowed to be connected to a branch within the chamber.
I await your reply,
Thanks
Dave
If I understand your question correctly, you are referring to a GRP or brick manhole with several branch connections within it...should you use a spare one for sole use as a vent or can you use a branch which is also being used for waste water from wcs, bath and basin etc.?
Assuming the foregoing is right, the answer to your question is either way is fine provided the Inspection Chamber is at the head of the drain run.
If in doubt refer to Building Regulations AD; H or your local Building Inspector.

Is there any way of overcoming blistering in below ground foul water pipes other than removing and replacing?
There are a number of no dig solutions on the market. The product development team at Fernco Environmental featured above have been very helpful with my investigations on your behalf. Fernco can provide a localised repair system called 'pipe doctor' which can be installed in 550mm - 1200mm lengths and is suitable for pipes with diameters of 75mm - 1200mm.
If the pipe has been badly deformed (as is often the case with pitch fibre pipes) depending on the severity, it may be possible to carry out reforming and lining. www.DrainDomain.com and www.pitgh-fibre-pipes-repair.com both offer further help and advice with this problem.
