What causes blocked drains?

Feb 10, 2023 | News

Blocked drains can be a nuisance for any homeowner. They can cause foul odors, slow water flow, and even create unsanitary conditions. Understanding what causes blocked drains is the first step in preventing them from happening.

The most common cause of blocked drains is the buildup of foreign objects in the pipes. This can include anything from food waste, hair, soap scum, and grease to toys, sanitary products, and tree roots. When these objects accumulate in the pipes, they can create blockages that prevent water from flowing freely.

Another common cause of blocked drains is the buildup of grease and oil. This is particularly true in kitchen sinks, where grease and oil are often washed down the drain. Over time, this grease and oil can harden and create blockages in the pipes. To prevent this, it is important to dispose of grease and oil properly, such as by wiping it from pans and dishes and throwing it in the trash, rather than down the sink.

Tree roots are another common cause of blocked drains. Trees are naturally attracted to moisture and can grow roots into pipes in search of water. This can cause pipes to crack, which allows more roots to grow into the pipe and create a blockage. If left unchecked, this can cause significant damage to the pipes and lead to costly repairs.

Poorly installed pipes and corrosion can also lead to blocked drains. If pipes are not installed properly, they can become misaligned, which can cause blockages and slow water flow. Corrosion can also cause pipes to deteriorate and become clogged with rust and debris, leading to blockages.

In some cases, what causes blocked drains is the sewer system itself. For example, if the sewer main becomes clogged, it can prevent water from flowing freely and cause blockages in the pipes. In addition, if the sewer system is old or poorly maintained, it can become damaged, leading to blockages and other problems.

Finally, clogs can be caused by flushing inappropriate items down the toilet. These items can include wipes, sanitary products, and other non-biodegradable materials that can create blockages in the pipes. To avoid this, it is important to only flush toilets with toilet paper and human waste.

In conclusion, there are several contributing factors to what causes blocked drains. Some of the most common include foreign objects in the pipes, buildup of grease and oil, tree roots, poor installation, corrosion, sewer problems, and flushing inappropriate items down the toilet. By understanding the causes of blocked drains, homeowners can take steps to prevent them from happening and ensure their pipes remain clear and flowing freely.
