I live in a trailer and have an inside furnace. The past month there has been a sewer odor comming from the heating vents. What could be causing it and what can be done?
If you have an air conditioning unit or humidifer, it is possable that there is a drain for the condisation. If the trap in the drain is dry of water, the furnace could pulling the oder through the ventalation system. Poor water in the drain and it should solve your problem.
