REGULATIONS RE STENCH PIPES ?

[nickwilber]

Hi. MY house has a single storey extension and I have a bathroom at the far end of the extension about 5 metres from the back of the main house. The stench pipe on the end wall is above the roof height of the extension. A neighbour has complained of smells from the drains and has said that the stench pipe is not high enough and should be above the main roof line of the house.
Is this right?

ps the extension has been in place as it is for about 15 years

No he is wrong, within 3m of any opening the pipe must terminate a minimum of 900mm above that opening.

You can shove this under his nose: http://www.planningportal.gov.uk/uploads/br/BR_PDF_AD_H_2010.pdf page 13 of the PDF

1.31
Ventilating pipes open to outside air
should finish at least 900mm above any opening
into the building within 3m and should be finished
with a wire cage or other perforated cover, fixed
to the end of the ventilating pipe, which does not
restrict the flow of air (see Diagram 6). In areas
where rodent control is a problem (see paragraph
2.22) these should be metallic.

You can get external Air Admittance Valves but they are only suitable if the system is vented elsewhere.

how far is this pipe from his house?

Do you have a "manhole" nearby? If there is a blockage the smell might be especially bad.
