Is it normal here in France to not have a soil pipe vent? We have odours in our ground floor summer apartment, eminating from the drains. The fosse itself does have a vertical vent pipe, the top of which is abou 1m above ground. That is roughly at the same level as the shower drain in the apartment. I have checked all u bend and traps, they do contain water so the waste pipes are effectively sealed from “ambient” odours.
In my epxerience in the UK, the waste pipes woudl also be ventilated, either by an external stack or an intrnal one, venting at roof height. I do not have ay such vent, nor do any other properties when viewed externally. The French nor seesm to be to keep all waste plumbing hidden wthn the fabric of the building so vents may be there, just not visible.
The fosse passed inspection for the sale ( Acte De Vente Decmeber 2107) so it seems nothing is untoward, apart from the smell!
The house is built on a slight slope, our main accommadation is on the ground floor at the higher edge of the slope and the apartment underneath on the lower part. All of the waste pipes in the apartment are buried into the concrete floor, and exit the apartment at a point that is probably 1 metre below ground level. In a cave for the huse the waste pipes from the house come together in an inspection point and grease trap, before exiting. That exit waste pipe is joined by the waste pipes from the apartment, for which I cannot find any inspection hole or grease trap
Anyway, my man uetsin is whether there should be a vent for the waste pipes at the accomadation end? If so, what are the conventions for such a vent?
