What is Sewer Gas?
Sewer gas is a byproduct of the breakdown of natural human waste. Sewer gas is composed of hydrogen sulfide, carbon dioxide, methane, and ammonia; the hydrogen sulfide is what gives sewer gas that intense, “rotten egg” smell. While not toxic in small quantities, sewer gas can cause health issues in larger quantities, as well as create a number of other issues to you, your home, and your plumbing.
Why does a sewer line freeze?
Unused or Dry Plumbing - If a sewer system isn’t regularly used, piping can dry up and make room for sewage gas to build up. Because water normally provides a barrier between the gas and the outside world, a dried up pipe or toilet bowl can allow gas to seep in. Additionally, an unused sewer system could also cause your leach field to freeze over (without the constant flow of house-temperature water, the field will freeze). The ice will cause the system to back up completely.
Why do toilets loosen?
Loose Toilets - In order to prevent septic gas from leaking out, toilets need to be tightly fastened to sewer lines. Even if your toilet was installed correctly, rubber linings and wax rings can wear away over time; it is normal and common for a sewer gas leak to occur this way.
