We help many homeowners with odor issues within their homes. From dead mice odors to cigar smoke, we have resolved many. The most common odor problem we find is plumbing system sewer gas.
Sewer gas can escape the piping system and present itself in several ways. Loose toilets, loose/broken piping, and blocked vents are common. The most common sewer odor is from plumbing traps that dry up and allow sewer gas to enter the living space.
As the below diagram shows, water in the trap blocks sewer gases in your drain. The water in the traps of unused sinks, toilets, bidets, and floor drains can evaporate, allowing the sewer gas to enter your living space.
Adding a few cups of water to fill traps to their required level is an easy first step in troubleshooting and resolving sewer gas odor issues.
