Size of vent stack?
What's the minimum size I can get away with for a stack ventilation pipe on
a single storey dwelling, it serves only for ventilation. It used to be 75mm but I haven't got access to the latest approved documents. Cheers Tom |

I don't think that the Hep VO traps apply, please advise me if you think the statement incorrect. Cheers Tom |

Sure you do: http://tinyurl.com/qjn7 or http://www.odpm.gov.uk/stellent/grou...hcst?n=240&l=2 Use HepVO traps and no vent pipe at all. http://www.hepworthplumbing.co.uk This is the main stack and is located external to the building, it's not a secondary stack.

Depends on various factors, eg whether next door already has an external stack: read this thread (and lots of others) from the uk.d-i-y archives for more info about it: http://tinyurl.com/6zpos David |
Much obliged for the info.
