Why is there a heavy sewer odor inside my property?

This is usually caused by the presence of a dry trap in a sink or floor drain that has not been used in a while. Pour water into the drain to fill the trap. This acts as a block between the normal organic odors in your sanitary plumbing and the living areas of your property. Another potential cause is a blocked roof vent. Each bathroom should be vented beyond the roof line to allow the plumbing system to operate properly and dissipate normal sewer gases to the atmosphere. Birds may find your vents an attractive nesting site and that can be a prime cause of vent blockage. Keep those vents clear and you will eliminate one potential source of sewer odors.
