We woke up today with a terrible sewer gas smell in the entire house, but it was worse in the upstairs bathroom and MUCH MUCH worse in the basement bathroom. The basement bath is rarely used. I have noticed that in the basement bathroom , if you open the door on the cabinet for the sink, it always has a faint sewer smell… but now the smell is much worse! It has been raining quite a bit this week, i dont know if that is a factor or not. Do you suggest anything to help?
This faint smell didnt start until after the sink was installed. When we moved in the drain was capped and we had a friend intall the plumbing for the sink. I dont know if improper venting is a factor, or even how to see if itis or not.
Thanks
Kim
