Have you noticed an odd odor in your home, especially when you are in a room with plumbing? If so, you may have a problem with septic gas leaking into your home from your septic tank. This is a serious problem that you need to address, because those foul odors contain hydrogen sulfide. Here are some common ways the gas can be getting into your home, and how you can fix it.
The reason you are smelling septic gas may be due to dry drains. When water flows out of a drain, it flushes out the gas to the tank. Unfortunately, a dry drain can cause those gases to seep back into the home.
A dry drain can happen when the trap is no longer filled with water and becomes empty. WIthout water blocking the path of air from the septic tank, it will flow back up the drain. This can happen in a bathroom that is infrequently used, such as a guest bathroom, and the water in the trap evaporates due to sitting in the trap for so long.
The easy solution is to simply run water through your sink and flush the toilet occasionally, which will make sure that water has filled the trap.
Clogged Ventilation Stack
Were you aware that septic gas is released from a ventilation stack on your home's roof? The stack is designed to extend several feet past your roof line so that the released gases enter the air and don't go back into your home through open windows. The problem that you may be running into is a clogged ventilation stack that is forcing the septic gas back inside.
You can solve this problem by having the ventilation stack inspected for a potential clog, and if there is, clean out the debris inside of it. This should allow the septic gas to be released without any issues.
The issue with leaking septic gas may be due to a gasket that is broken on your toilet. The gasket is located around the toilet's base, and it creates a seal between the sewer line going to the septic tank and the toilet. A broken gasket will cause septic gas to leak inside the home from your toilet's base. Replacing the gasket is easy, and is a job you can even do on your own with the proper directions.
