As organic waste in septic and sewage systems decompose they produce gases that are toxic when inhaled. These gases are also known as sewer gas, rotten egg smell gas, and other names like biogas. This is not something you want to have in your home or business and it is important that the problem be resolved immediately.
The most common way that sewer gas meter gets into a home is through a cracked or broken p-trap or plumbing drain vent pipe. This is why it is so important to hire a pipefitter who has experience relining pipes. Relining is a permanent fix for leaking or broken plumbing and will keep your family safe from the dangerous gases produced by faulty plumbing.

Another common way sewer odor enters homes is through a failed toilet wax seal or an uncapped toilet drain line. This is also why it is so important to use a toilet that has a seat cover and lid that are properly secured. This will prevent sewer odor from entering the house and help to keep the toilet clean and sanitary.
The simplest and most inexpensive way to find the source of a rotten egg smell or sewer gas is through an odor detection test commonly referred to as a smoke test. A professional plumber can perform a smoke test and identify the leak point in your plumbing system. For those that are more budget-minded a small portable meter can be purchased that will detect the presence of combustible gases such as methane, propane, and butane, which may be present in sewer gas.
