1. Why is the septic tank full of water and has an unpleasant smell?
To have the right intervention when your septic tank is full of water and smells bad, you need to understand the cause of this situation. In fact, there are many reasons why septic tanks are full of water:
- The toilet is clogged with hard objects and waste such as paper, hair, grease, leftover food, etc.These substancesstuck in the toilet drain pipe, preventing water from draining and causing a water overflow situation.
- Soaps and toilet cleaners contain many chemicals and kill beneficial bacteria in the septic tank. Therefore, the process of decomposition and liquefaction of waste in the septic tank is impairedslow down. This is also the reason why the septic tank has a foul smell and quickly fills with water.
- Septic tanks that have been used for too long without being upgraded or maintained cause the pipe system to deteriorate and cause blockages and water overflow.
- A reason that few people pay attention to is the wrong technical design of the septic tank or the incorrect construction of the slope. When the drainage pipe does not meet the standard tilt, waste and water easily stagnate in the middle of the pipe, forming thick plaque over time, reducing water circulation.
- Households with a large number of users but a small septic tank also cause the septic tank to fill up faster than usual. Flushing toilet paper, wet towels or household grease down the toilet every day is a wrong habit that causes the treatment system to be overloaded after just a few years of use.

3. Harmful effects when the septic tank is full of water
A full septic tank not only causes an unpleasant odor but also poses many potential risks to health and the surrounding living environment. When wastewater cannot drain, methane and ammonia gases produced during waste decomposition will accumulate, causing suffocation and can lead to poisoning if inhaled for a long time.

Not only that, if left for a long time, increased pressure in the septic tank can cause the septic tank to crack, damage the structure and incur large repair costs.
In some cases, wastewater seeps into the ground and pollutes underground water sources, affecting neighboring residential areas. Therefore, when you notice signs that the septic tank is full, you need to handle it promptly to ensure health safety and maintain the hygiene of the living space.

After using septic tank treatment yeast to overcome the situation of a full septic tank, you also need to pay attention to minimize the recurrence of this situation. Here are some notes that families should definitely remember:

- Do not pour leftover food or garbage into the toilet as this will cause the toilet to become clogged.
- If your family has young children, you should close the toilet lid after use to avoid children throwing toys into the toilet.
- You should use a trash can to store toilet paper after use. Do not throw toilet paper into the toilet. Because accumulating too much toilet paper will cause pipes to become clogged and difficult to decompose.
- Periodically pour septic tank treatment yeast EMZEO Duc Binh into the toilet every 3-4 months to ensure that the septic tank is always supplemented with beneficial microorganisms and decomposes waste in the septic tank. This helps the septic tank become more airy.
- You should check the septic tank vent cover every 6 months. Many families have air reflux and bad odors just because the vent pipes are covered with dust or trash. When ventilation is poor, the fermentation process in the cellar will create pressure, causing the waste to not decompose completely.
- You should flush strongly 1-2 times a week to wash away debris in the pipes. If your area has a high water table, choose a dry time to maintain your cellar to avoid backwater seepage.
