Understanding How Yeast Can Help Your Septic Tank

Septic tanks require that the waste material in the tank maintain a specific bacteria level. That bacteria breaks down waste material to help you avoid septic system backups. While you still need to have the tank pumped on a regular schedule, maintaining the bacteria is equally important. Although there are many different products available on the market for this, you don't always need to invest in something commercial and costly. In fact, products like yeast are great for helping the bacteria in your septic tank grow and thrive. Here are the basics of using yeast to help your septic system function.

How Does Yeast Work?

Yeast provides an environment where the bacteria in the septic tank can thrive. The yeast helps to combat the damage done by antibacterial cleaners and other products that get rinsed down your sink drains on a regular basis. These products kill bacteria, so you need to account for that. Since yeast feeds bacteria, it can help you restore that balance when applied to the septic tank on a regular basis.

When Should You Add The Yeast?.

If you're going to add yeast to your septic tank, you need to do it at a time when there won't be any disruption in the system for several hours after the application. That means that it is usually best to treat the tank at night before everyone in the house goes to bed. That allows the yeast the entire overnight period to function before you introduce any water to the system again.

How Should You Add The Yeast?

Heat three to four cups of water in a saucepan over medium heat. Choose a pan that's larger than you'd think you need. Heat the water to a boil and add two to three of cups of sugar. Stir the mixture until the sugar is dissolved. Move the pan off the heat and add two to three cups of cornmeal. Let that mixture sit until it's completely cooled.

Once cool, add two packets of instant yeast. Stir the whole thing until the yeast has dissolved. Let it sit for up to an hour, or until you can see brown froth on the surface that indicates that the yeast is active. As soon as that happens, dump the whole thing in the toilet. Flush it, and then flush it a second time to encourage everything through the pipes.

With routine yeast treatments and frequent septic tank cleaning and pumping, you can keep your septic tank running at its best.
