We have a newly constructed home W/Walk out bacement. once in awhile we have sewer type smell in the bacement that I cannot pinpoint anywhere. It is on a 2-500 gal septic tank system W/leach field the PVC under bacement floor is 4″ and vent out of roof is 3″ could this be a cause? is is a possibility that the PVC bipe broke under the floor? I would think the stink would be here all the time if that was the case. it is really almost unbearable some days I really am at a loss about where it is coming from … I have 1 floor drain I add water to to keep it full and fresh. I have allot of stink from my roof vent pipe I can smell at ground level is there a set standard for how high a vent pipe should be in relation to itch and location from peak on these? or do I just put on a filter?
I am afraid this smell is going to ruin our new carpet soon. I appriciate plumbers and could really use the help.
