To prevent having a smelly drain in the bathroom and kitchen, it is important to know the source. Once you find the source, you can plan on how to get rid of the bad smells. Here are the most common reasons why you have a smelly drain:

Bacteria and Clogs – Tons of food, hair, and other materials can accumulate in pipes over time, causing blockages that cause odors and poor water flow. If you notice a foul-smelling drain in your home, the culprit may be an object blocking the pipes.

Food with a pungent smell – Onions and seafood can leave a strong smell when they cook. This can cause unpleasant odors in drains.

Spoiled or rotten food – Food and grease can accumulate inside your kitchen pipes, which can cause a foul odor. Smaller food particles can gather on the pipe walls if you flush a lot of food down the sink. These particles can begin to decay and produce a putrid smell.

Gases from the sewer – By design, sink traps neutralize sewer gases that pose health problems. However, these devices can malfunction, allowing sewer gases to enter a home. A telltale odor of rotten eggs indicates the presence of a malfunctioning trap.
