6 Most Common Causes for Drainage Blockage

Drain clogs can happen at any time of year, however some are seasonal due to lifestyle and climate variations. If your drain is clogged, you must first determine what type of drain it is. Is it sewage or rainwater?

Inside the home, when utilizing the fixtures in the kitchen, bathrooms, and laundry, the blocked drains create the most anxiety and annoyance. These will be linked to your sewer system.

The removal of major pipe clogs will necessitate the assistance of a plumber. With a few maintenance recommendations, you might be able to avoid the clog altogether.

Here are some of the common reasons for clogged drains in the house, as well as some solutions.

  • Fats and Food garbage

Food and fats are infamous for clogging pipes, especially during the winter.

Food scraps should always be thrown away rather than flushed down the toilet. Foods that swell in water, such as rice and pasta, might clog your sink.

Fats are also bad for your drains and the shared sewer system. Fatbergs are the solidification of oils and fats that have been flushed down the drain, causing a mass to form in the drain. When fats enter the sewer, they solidify due to the cold temperatures, and they combine with wipes and other particles to form a large-scale fat pile.

Our sewers are clogged by these fatbergs, which can cost millions of dollars to remove and maintain the waste management systems.Avoid rinsing fats and oils down the drain to avoid fatberg formation. Allow them to harden before scraping them into the trash.

Alternatively, if there are any small traces of oil on the plates, make sure to rinse them with hot water. When dishwashing liquid reaches the drain, it will disperse the tiny oil residue.

If you suspect fat residue is clogging your sink drain, pour boiling hot water and dish washing detergent down it to break it up. With this natural cleaning method, you may also use bicarbonate soda and vinegar.

  • Toys and/or Other Unknown Objects

Although flushing small solid objects down the toilet can be avoided, it is occasionally unavoidable with children as you can’t always keep an eye on them.

But, you must be concerned and make sure that neither toys nor any hard objects are flushed down the toilet. They might get stuck in between the drainage pipes and can cause a serious problem in a longer time.

If the situation gets worse with the blockage, even plumbers might need help to solve your drainage problems. So, we advise, don’t do that.

  • Back fall of Drainage Pipes

Ground movement or improper drain installation can occasionally be the source of persistent clogs. To allow waste water to flow, waste pipelines must have a fall. Blockages are unavoidable when there is a flat line or a back-fall.

The best approach to determine where the drain has back-flow or has a belly (dips down and then rises) is to use a drain camera, and a plumber will need to provide a price for replacing this portion of pipe. Constant calls to unblock blockages can be pricey, as well.

  • Heavy Storms and Rain

Drains outside are clogged by leaves, dirt, and other debris after heavy rain or storms, causing the drains to clog. 

People frequently experience drainage system blockages because they were not designed to handle high amounts of water. As a result, flooding outside the home is a possibility.

  • Poor Pipe Installation

Many issues have arisen as a result of the growing tendency of “doing work on your own.” This is due to shoddy drainage pipe installation and untrained plumbing. 

Any pipe might be damaged if it is installed incorrectly. To avoid common plumbing problems, make sure you use high-quality pipes. If you install pipes poorly, you risk causing harm to other areas of your home. In terms of money, this might be pricey.

Make sure you hire professional and/or experienced plumbers who can help you with proper pipe installation.

  • Water Flow Problems

It is self-evident that drainage is a gravity-based process. If you are untrained, you may create insufficient falls, resulting in a regular build-up of dirt and debris, clogging your pipes. 

As a result, ensure that pipes are properly installed with appropriate falls. This isn’t the sole explanation for clogged drains; there could be a number of other factors at play.

You will notice some warning signals before a major problem occurs. These include gurgling sounds in the toilet, a foul odour coming from the drains, and water left in the sink. Some of these can be quickly remedied with a plunger, while larger issues are more difficult to solve.


When we consider all of these issues, it becomes clear that we need to have regular checkups to avoid costly complications. 

As a result, make it a habit to call the plumber on a frequent basis. This will cost you some money in the short term, but it will save you money in the long run.
