Where Do Most Clogs Occur in House Drains?

Whether your house drain pipes carry water or waste, they are susceptible to clogging when neglected and not properly maintained over time. When there are clogged drain pipes, the entire plumbing system is affected and is at risk of extensive damage. Additionally, having clogged pipes in your house brings potential danger both to its structural integrity and your health.

To avoid clogging, it is crucial to know its causes and where it usually occurs. Besides practicing preventive measures, calling in professional plumbers for routine cleanup and maintenance is highly advisable.

Most Common Household Clogs

Although clogging can occur anywhere in a residential property’s plumbing system, some areas are more susceptible compared to others.

To give you an idea, here’s where the most common household clogs occur:

1. Toilet Drain Pipes

Since toilet pipes carry and transport human waste, their being clogged poses health risks. They can be a breeding ground for numerous bacteria, germs, viruses, and other microbes that harbor contagious diseases. Besides carrying waterborne diseases, foul smells coming from them are also one of the causes of the proliferation of airborne contaminants. Since clogged drains are more dangerous than people think they are, addressing them as quickly and appropriately as possible is needed.

To prevent clogging in your toilet drain pipes, avoid flushing feminine hygiene products, diapers, flushable wipes, plastics, condoms, and food waste down your toilets. Aside from the previously mentioned items, other things can cause clogging in toilet drains as well.

Some of which are the following:

  • Having an older toilet model
  • Blocked toilet vents
  • Clogged toilet traps
  • Clogged sewer lines
  • Too much toilet paper

2. Shower Drain Pipes

If you’ve been wondering what causes clogged drains in your shower, here are the most common:

Hair and Dead Skin Cells

When you bathe, your body naturally sheds dead skin cells and strands of hair. These things stick to the walls of your shower drain pipes. They accumulate over time and block the flow of water, causing clogged drain pipes to occur. As much as hair catchers can help, shower drains pipes will still experience clogging at some point. For that reason, calling for regular cleanup services is recommended to prevent costly repairs brought about by clogging.

Soap Scum

One of the major causes of clogging is soap scum. Its deposits on the walls of pipes cause hair, dead skin cells, and other things to stick and block the flow of water. To prevent the excessive accumulation of soap scum, pour a few buckets of hot water mixed with chlorine bleach down your shower drains on a weekly basis.

Hard Water

Hard water is also a cause of clogging in shower drain pipes. Like hair, dead skin cells, and soap scum, hard water is known to contain micro solids and minerals that stick to the walls of drain pipes. These micro solids and minerals, together with the other mentioned causes, make it harder for water to flow as they decrease the cross-section of drain pipes. To avoid hard water from causing clogging, professional plumbers can install a water-softening filtration system to your plumbing fixtures at home, especially the showers.

Trash and Other Small Items

While taking a shower, there are small, unnoticeable items that can be flushed down your shower drains. Consequently, they can get stuck in the drains, causing clogging to occur.

Some of these items are the following:

  • Razor Coverings
  • Toothpaste Caps
  • Pieces of Plastics
  • Shampoo Caps

3. Kitchen Sink Drain Pipes

Kitchen sinks are also one of the common plumbing fixtures that get clogged from time to time.

Oftentimes, clogging is caused by the following:


Food waste from washing the dishes is considered the main cause of clogging in kitchen sinks. They get washed off of different kitchenware and flushed down kitchen sink drains. Usually, sinks have a J- or P-trap that catches food waste, preventing them from clogging the pipe system of your house. Over time, food waste accumulates in the trap and causes clogging to occur in kitchen sink drain pipes. Here are some of the most common food waste that gets flushed down drain pipes:

  • Coffee grind
  • Rice
  • Small pieces of bread
  • Meat
  • Chicken bones
  • Eggshells

Fat, Oil, and Grease

Fat, oil, and grease are also among the culprits that cause clogging. These substances create sticky sediments that trap food and other small objects, causing clogged drains to occur over time.

Signs of Clogged Drain Pipes

If you suspect that you have clogged drain pipes but are still not sure, the best course of action is to call professional plumbers to assess the condition of your entire plumbing system. Meanwhile, be on the lookout for signs of clogging.

Here are some of them:

  • Water or sewer backups
  • Gurgling noises in house drains
  • Unusually slow flow of water in your shower and sinks
  • Plumbing fixtures reacting to each other when being used
  • Presence of foul odors
  • Bubbles in the toilet when running water in the nearby sinks
  • Accumulation of water
