I rent my place and I reported the sewage backing up two months ago and maintenance people came and pumped it out.. The maintenance men told me they were going to have to get a tractor out here to dig up and find the lines so the can see if it is stopped up.. I keep telling them I smell it in the house. How can I get them to come and fix the problem, and is the smell dangerous to me and my children. What steps do I take to get them to do this job?
