7 Common Causes of Blocked Drains and How to Prevent Them

Food scraps

Food leftovers are one of among the most frequent reasons for clogged drains.

Foreign substances

Toys, jewels, money, and other tiny objects that may have recently washed down the toilet cannot be handled by plumbing systems. As more debris gathers around them, these items may become lodged in the sewer line and eventually block it.

Infant wipes

Although flushable wipes are frequently touted as being safe with plumbing systems, they occasionally don’t degrade as soon as claimed. These items have the potential to clog your pipes with a deposit of thick, slimy material.

Tree Roots & Blocked Drains

Large trees and bushes growing close to your house run the risk of having clogs caused by the roots penetrating the pipes. This is particularly true if the plumbing fixtures are older or composed of delicate materials, like clay.

If there is a fracture in the waste pipe or when the underground root system is powerful enough to force its way through it, tree roots will enter it.

Some plumbers contend the pipe has to have already been damaged before the penetration and that tree roots couldn’t have caused the breach. In any case, tree roots damage pipelines.

Paper towel

Paper towels that have been thrown down the toilet in large quantities are typically the culprit for clogged drains. Use just a modest amount of toilet tissue each time you flush, and avoid flushing objects like sanitary pads, to prevent this.

Oil and fat

When hot water is used to clean the sink, oil or fat can freeze and build inside of your pipes.

If this is not fixed right away, it may result in sluggish drains, unpleasant odors, and finally a blockage. In addition, drain cleaning products can aid in reducing oil and food debris before it accumulates.

Food and fats are infamous for clogging pipes, especially during the winter. Never flush food leftovers down the drain; instead, put them in the trash. Foods that expand in water, such as rice and pasta, might clog your sink.

Additionally, fats are bad for your drains and the public sewer ( system.

Oils and fats that have been flushed down the drain and solidified into a clump in the drain are known as “fatbergs.” When fats reach the sewer, the cold winter weather makes them solidify, and when they combine with wipes and additional particles, they form a substantial fat pile.

Our waste disposal facilities may need to spend millions of dollars on removal and upkeep of these fatbergs, which clog our sewers.

Don’t flush fats and oils into the drain to stop a fatberg from forming. Scrape them out of the trash after allowing them to harden.

Alternatively, be careful to rinse dishes with hot water to remove any little oil residue. When oil residue enters the drain, dishwashing liquid will spread it out. If you believe that fat residue has clogged your sink drain, use hot, boiling water and dishwashing soap to clear it.

Mineral accumulation

When water requires longer than usual to flow away, it may be a symptom of a blocked drain. This could be brought on by the accumulation of calcium or limescale in the pipes. This may result in water that is obstructed and moves slowly if left untreated.

It’s crucial to locate the issue’s origin if you’re having plumbing problems in your house so that one can fix them as quickly as feasible. There are several clogged drain solutions that can assist you in identifying and fixing any plumbing issues you might be experiencing.
