I've had tenants in my basement for 3-5 years. House is 30 years old. A stinky smell comes from the tub in basement. It comes and goes but is mostly always there.
Were do I start looking? The fixtures are used so all the traps are filled. Poor workmanship is a possibility but since it hasn't happened for years I tend to think leafs are blocking the pipes or something else.
The smell came _before_ I got the roof worked on, it's still there.
Can I blow (one second plumber) in the tub to push shit out? Any other suggestions?
thanks all cln
