Hi, I have had an odor in the house for the last 8 weeks and still can't track what it is. It smells like gas at times. The funny thing is that we don't have gas at all. I had a plumber come through all he did is smell the sinks and my vent stacks and said my plumbing is fine. Its not a dead rat or mice the smell gets stronger more during the day and not at night. How can I detect if I have a pluming leak somewhere do I replace all my traps and seal please help.
Regards,
Laurie
