For several weeks now I have had a bad smell in my kitchen. I had a plumber come out about a month ago to fix a pipe that had a hole in it that was under my kitchen. They put lime, and later on fogged under the house to get rid of the smell. I am going to have them come back out next week to see if they can see if there is something wrong with the waste arm. I want them to put a video camera down the kitchen sink to see if there is something else broken. My question is is the smell hazards to out health? I have 4 children. Two of them are 2 year old twins. Please respond to my question...
