Water in sink, toilet, shower smells like sewer. What can cause that?
I live Tuesday - Friday in old 2-story rent house. When I return each week, the water in all sinks, toilets and showers smell like sewer. Nobody in neighborhood has problem but me. After running water for awhile in each fixture, smell goes away. This problem has been ongoing since I moved in a year ago. Could it be a venting problem? I don't have washer/dryer, but there are hookups and former tenant said her clothes smelled bad from time to time. Please help me diagnose this problem! Thanks!
