Why Does My Septic Tank Smell at Night?

Have you noticed that your septic tank smells worse at night? If so, this is an indication that something has gone wrong and action needs to be taken to get things in good working order. In this blog post, Septic Blue of Raleigh explains why a septic tank might smell at night and the possible solutions.

Septic Blue of Raleigh is a professional septic company providing a comprehensive range of septic services, including septic tank cleaning. If you need septic help, do not hesitate to call us.

  • Full Septic Tank

A full septic tank is a common reason why an awful smell may be seeping into your home. A septic tank holds a limited wastewater capacity based on its size. When the tank is too full, it becomes hard for the tank to process the wastewater efficiently. The waste generated from your household cannot settle properly because of insufficient space in the septic tank. The gasses produced in the septic tank will have nowhere to go but find their way into your home through the vent pipe or drains.

If your septic tank is full, schedule septic tank pumping as soon as possible to address the unpleasant odors permeating into your home. The sludge level in a septic tank should be no higher than one-third of the tank’s total depth. If you’re dealing with a smelly septic tank, contact nearby septic tank technicians to check how full the tank is and advise you accordingly.

  • Septic Tank Cover Not Sealed

A septic tank is equipped with a watertight lid that keeps out debris, rainwater, animals, and foreign objects. The lid maintains the integrity of the septic tank while preventing odors from escaping into your home. If the lid is not fastened properly, the gasses will escape into your home, causing unpleasant odors and health hazards. The odors tend to linger at night when air currents are weaker. If your septic tank cover is broken or needs to be fastened properly, call a professional septic company for help.

  • Blocked Septic Vent

A septic tank vent facilitates proper airflow and the release of noxious gases from the tank. Septic vent stacks can get clogged by bird nests, debris, animals, and other foreign objects. A clogged septic vent will prevent the gasses from exiting the tank. When the gasses inside the tank are obstructed, they will eventually find their way into your drains. It’s a good idea to inspect your septic vent stacks regularly and clean them to prevent blockages. You can seek help from a professional septic company if necessary.

  • Failing Septic Tank

A septic tank can last anywhere from 20 to 40 years. Sadly, as with other components of a septic system, septic tanks don’t last forever. If yours has seen better days, it’s more likely to let noxious gasses escape into your home. Another problem with an aging septic tank is that its capacity to hold wastewater gets diminished. Excessive sludge buildup can cause an awful smell to permeate into your drains or through the vent pipes. If it’s time to replace your septic tank, call the experts at Septic Blue of Raleigh for a new septic tank installation.
