Adding enzymes, bacteria, and yeast to your septic tank: Do They Work? Pros and Cons

A septic tank is an essential part of a home in a lot of rural areas. Bacteria and enzymes break down the sludge and process it into cleaner water. Sometimes people want to add enzymes or bacteria to the tank to make it work better.

There is a lot of debate over the benefits and risks of these in septic tanks. Some people believe that bacteria and enzymes can help to break down organic waste, while others argue that it can actually cause serious problems in a septic tank. If you are considering using yeast in your septic tank, be sure to speak with an experienced professional before making any decisions.


 What are bacteria?

Bacteria eat the sludge in your tank and process it in cleaner water. This results in different layers in your tank. The dirtiest layer is on top, the cleaner layers are at the bottom. Bacteria are alive and can produce enzymes. Enzymes are not alive but can boost bacteria to work harder. 

 Bacteria can multiply whereas enzymes can’t do this on their own. A healthy tank has bacteria and worms that break the sludge down. We want proper water and effluent to go in the drain field.  It can take a while before bacteria appear in your sludge. This is why septic tanks can be quite big. Bacteria need time to do their work. 

What are Enzymes?

Enzymes are proteins that speed up the breakdown of sewage water. Bacteria can produce this. It is a family of different types of proteins that can process waste in your tank. They can work very fast and therefore they are often seen as a great way to break down sludge. Normally this should be present in your septic tank already.  

What is yeast?

Yeast is a type of fungus that is used to make bread and other sweets. It is usually added to septic tanks in order to break down organic waste. If you are using yeast in your septic tank, be sure to speak with an experienced professional before making any decisions.

What are the benefits and risks of using bacteria, yeast and enzymes in septic tanks?

The benefits of using yeast in septic tanks include the following:

-Yeast can help to break down organic waste, processing the sludge faster.

There are several brands and formulas out there. Be sure to check what they contain before you add them to your tank!

Do bacteria, yeast or enzymes work in a septic tank?

There is no one-size-fits-all answer to this question, as the best way to determine if yeast is appropriate for your septic tank may vary depending on the specific needs of your tank. Generally, you don’t need to add anything to a sewage tank as it will work on its own. If there are problems, the easiest way to fix them is to pump the tank. They pump the tank completely empty so the process can start from zero again.

It is possible that yeast helps but you have to measure how much needs to be added. This can require complex analysis and often it is cheaper to just pump the tank. It is also possible to check the tank to see if it is leaking or if there are other issues. Sometimes the tank is too big or too small for a home. 

You have to use a septic system correctly if you want it to function well.

This includes not using a garbage disposal. You shouldn’t use your washing machine too often. Don’t drain your pool in the sewage system. Don’t use chemicals when you clean.  You also shouldn’t flush wet wipes or towels.

It can take some getting used to this and you might have to inform guests. This makes sure that the septic system is working optimally. If you don’t want to do this, you can consider adding bacteria and see if this works. It can be difficult to know how much you have to add though. If you add too little, it won’t work. If you add too much it can damage the processes in your tank. This might lead to more costs as you have to pump your tank more often. 

Some of these products have been around for more than 50 years so they shouldn’t harm your system. If they work depends on your system and how often it has been cleaned.

Most plumbers don’t recommend them as they are generally not needed. If there is a problem with your septic system, you should get it inspected with a camera to see what is going on.

What are the consequences of using bacteria, yeast or enzymes in septic tanks?

The consequences of using yeast in septic tanks can be a variety of different things. In some instances, it can help the bacteria somewhat to work faster. Adding some yeast or enzymes is generally not a problem but is not really needed. People often want to overdo it. Save your money and spend it on an additional pumping of the tank. 

If you have a large amount of organic material in your tank, enzyme use may not be able to effectively treat it. Additionally, these enzymes may also cause serious problems for the environment if used excessively or over time.

Your tank has to be pumped every 2-5 years. This is quite expensive as it can cost more than 500 USD. Some people try to prolong this process to save money. Using yeast or enzymes can work but it also can have negative consequences. Having an inspection done can help to make sure that the sludge in your tank is being processed. 

You can clean the filter in your sewage tank as well. Always check with a professional before you work on your tank.

To conclude, we can state that adding some yeast or enzymes to your tank will often not be a problem. It is not needed to do this though. Just inspect and pump your tank when needed and don’t use items that can disrupt the bacteria in the tank (such as harsh chemicals).

It is often sold by scaring people but generally, this is not needed in your septic tank. In some instances, it can help though so be sure to check with the company that pumps your tank. They can check what is needed.

Septic tanks are important in a plumbing system. If something goes wrong, it is important that you troubleshoot to find out what is going on. A lot of people just add enzymes and other items to find a quick fix.

There are quite a lot of things that you can’t flush if you have a septic system, it is often more important to focus on this instead of adding items to the tank. A lot of research has been done on septic tanks and in most cases, it is not needed to add enzymes.

If there is a problem with your tank, you can hire a plumber to check what is going on. They have cameras to do this and can look into each part of the septic system.
