Did you know that roughly one out of every four homes in the United States uses a septic tank? If you have a septic system for your home, it’s essential that you take care of it so that you avoid problems such as foul odors, slow drains, and wastewater backups. A septic system is powered by gravity, and water flows out of your home, into the septic tank, and out into a drain field. In the septic tank, lighter materials float to the top, while materials heavier than water will sink to the bottom. As new water flows into the tank, water that has been sitting in the tank is forced out, where it is absorbed and filtered by the ground. Be sure to schedule professional septic tank maintenance in San Francisco every one to three years to keep your tank in working order.
