What to Do if Your Drains Smell Foul
A properly maintained residential septic tank should never smell. That means a bad odor inside the home or near the leach field is not a good sign. Smelly septic tanks are a result of the presence of gasses in the system, including hydrogen sulfide, carbon dioxide and methane. The pH levels in these gasses are too acidic for the microorganisms in the tank to digest the organic matter, causing the tank to smell. Not only are these odors unpleasant, but a high concentration of a combination of these gasses can be explosive or even toxic. Luckily, septic tank odors may be remedied relatively easily using a few common household products.
