: We have a shower drain that has been draining slow for about a week now. Yesterday I noticed a sewage smell coming from that drain. The shower had NOT recently been used. We live in the city of Appleton. Any ideas on what it might be?? Also yesterday I poured a drain cleaner down the drain (twice according to directions) and the odor seems to be getting worse. The drain cleaner helped the water drain a little faster but the water still backs up in the bottom of the shower. The water appears clear.is the water backing up when other fixtures are being used? if so then you probably have a line blockage that is causing sewer gases to bubble back through this drain.
