Upon arrival the customer had a sewer smell coming from the bathroom in the basement. When inspecting the toilet there is also a man line cleanout in the wall next to the toilet. I couldnâ€™t smell anything until I got real close to the back of the toilet and cleanout. The sewer smell was faint. I presented options on pulling the toilet and installing a new wax ring and for the cleanout I explained to the customer that we would have to cut into the wall and locate if the smell was coming from there. Customer declined at this time.
