3. Causes of sewer odor
How to treat sewer odors will focus on keeping the drain or waste line clean and eliminating odors. So, what causes these bad odors? Mostly, the cause is because of stagnant garbage or wastewater but there are still some other causes.

What is the cause of the bad smell?
Insufficient or little drainage
If one or more drains in your home are left unused or used sparingly for a long time, it will cause bad odors. Drains are always designed and manufactured to contain beneficial bacteria. These beneficial bacteria will have the ability to deodorize the drain, but if you do not flush the water for a long time and leave it alone, the beneficial bacteria will die.
These beneficial bacteria must have a certain humidity to survive. Regularly flushing water down the drain not only helps remove residue but also helps beneficial bacteria eliminate odors. Rest assured that the probiotics have a certain adhesion and will not wash away completely.

Dirty water stagnation
One of the popular and simple ways to treat sewer odors is regular cleaning. Because if you do not control and understand the condition of the drain, it is very possible that the drain is clogged without you knowing. When clogged, dirty water and waste stagnate underwater, causing a foul smell.
During daily activities, personal waste or food, garbage… is washed down the drain but does not float away but remains suspended in the drain, causing a bad smell. Especially some hard-to-decompose residue, grease, things made of plastic… will cause the drain to become clogged and cause a very bad stench.

Stagnant water causes stench.
Do not clean regularly
Different from regular cleaning, rinsing is a little different. For sewers, the sludge at the bottom will support waste decomposition, providing an environment for beneficial bacteria to grow and decompose necessary waste. However, when a long time has passed, you need to clean them.
4. Effects of stench on health
Why do we need to find a way to treat sewer odors? Because the stench will affect the health of people around. The stench of wastewater is mostly caused by decomposing organic matter, including H2S gas. Normally, we do not feel the harmful effects of this gas, but if it accumulates for a long time, it will cause a great impact on human health.

- Finally, pour warm or slightly hot water into the drain to help clean the pipe and flush out the coffee grounds. Note, you should not use water that is too hot because it can affect the plastic water pipes.
