I have been reading the problems others have had w/sewer gasses, also the dangers. My neighbor is curently having severe problems. She has had a plumber who has NOT solved the problem & is at her wits end as to what to do. The house is about 22 years old. This problem has only been going on two weeks now and no one has been able to solve it. The odor is so bad they have left the house tonight as they are feeling ill. Can you give some sugestions? There is a lower level bath room w/a lift station. The main floor bath room has a regular sewer hookup. Please help!! We would be ever so greatfull!! Thank you for any help you can give!!
