The bathroom tub backup from our septic. So we had it pumped out but the smell just is getting worse and worse. we have a towel under the door and we covered the sink and tub drain with a rag, so the smell would not go through the house well it is getting out the house smells really bad . we live in a rural area, so we called a plumber that we used before and he was great, but he is sick now, so if you have any information on that. it would be highly appreciated.
