Common Septic Tank Service Questions

Several things can ruin a septic tank over time, including dumping harsh chemicals (like bleach and ammonia), pesticides, and paint thinners down your drain because they can kill the bacteria in your septic tank. You should also make sure to only flush waste and toilet paper in your toilet—otherwise, you could clog your system.

Pumping involves opening the tank lid, removing solids and wastewater, and inspecting components for wear or damage to maintain optimal function.

Most septic tanks need to be emptied every 3 to 5 years, but it’s a good idea to monitor the fill levels of your septic tank all the time. You can do this by installing a pressure level sensor to detect the internal tank pressure, or by having a septic tank company perform an annual inspection to let you know when you’ll need to pump the tank.

When a septic tank is full, it needs to be professionally pumped. The average cost of a one-time septic tank pump is about $400, or $0.30 per gallon. If your septic tank is full, you may notice that you have issues flushing your toilet, pipes are draining very slowly, or you have a sewage smell lingering in your home or yard.

Baking soda does very little to nothing for a septic tank, but it can help unclog a drain or clean out a garbage disposal. Rotten tomatoes and yeast are the best ways to increase the bacteria in your septic tank naturally. You can add these to your system once every three months.
