our house is less than a year old. Due to a stopped up filter in the septic tank we had sewage back up in one of our toilets. That propblem is fixed but we still have a strong sewage smell in both bathrooms! Can anyone give us an idea of what is going on? I am at my witts end and can't believe that our new house smells like a sewer!
You may have a compromised wax ring under the toilet. Try pulling and resetting the toilets.
