Understanding Common Causes Behind Drain Blockages and Effective Solutions

Understanding Common Causes Behind Drain Blockages and Effective Solutions

As homeowners, it is easy to overlook the intricate workings of our plumbing until a clogged drain disrupts our daily routines. The unnoticed complexity of these plumbing issues often leads to their neglect, despite the profound impact a blockage can have on our homes and lives. Beyond mere inconvenience, a clogged drain poses risks to both property value and our comfort, potentially escalating into more severe issues like leaks or pipe damage. 

Amidst the hustle of daily life, addressing even minor blockages becomes crucial to prevent costly renovations and maintain a pleasant, odor-free home environment. To safeguard against these disruptions, it is vital to recognize the typical culprits behind drain blockages and employ effective solutions or consider a plumbing company promptly.  

Know the Common Causes of Clogged Drains 

So here we will mention some common causes of clogged drains to help you understand your basic plumbing needs! 

Tree Roots  

In areas with lots of greenery, like your home, encountering some wildlife is not unusual. But sometimes, those lovely trees can cause trouble by sneaking their roots into your pipes, especially if your home is older. 

You might notice this when your pipes start making strange gurgling sounds. Why? Well, those roots love water, and your pipes are an easy source. Once they are inside, they grow fast and block the water, causing plumbing issues like low water pressure or slow drains. 


If you live around lots of trees, it is smart to check your pipes every few years. It is much cheaper to stop the roots before they cause big problems than it is to fix things once they have done damage. Consider installing physical or chemical barriers around your pipes to deter root growth. 


When planting trees or shrubs near your home, opt for species with less aggressive root systems. Position them away from underground pipes to minimize the risk of intrusion. If you notice roots starting to infiltrate your pipes, consider root removal methods. 

Engage the services of a professional plumber or arborist to manage tree roots near your pipes. They can offer advice on root trimming or removal while preserving the health of the trees. 

Toilet Paper 

Toilet paper stands as a major culprit behind clogged drains, but the larger issue lies in the safe disposal of supposedly flushable items like wipes. Despite their “flushable” tag, these wipes don’t break down and end up causing blockages, disrupting waste disposal systems. 

Moreover, an excess of paper products such as tissues, baby wipes, paper towels, and lightweight cardboard poses a similar threat, overwhelming drainage systems beyond their capacity to handle these materials. 

Prevention and Solution 

Remember, the only things suitable for flushing down toilets, drains, or sinks are water and human waste. Any other foreign objects should be disposed of responsibly in trash, compost, or garbage disposal for recycling. 

For minor toilet paper blockages, using a plunger, toilet auger, or chemical drain cleaner might offer a solution if water still flows through the toilet after flushing. But if the issue persists or becomes more severe, it’s crucial to seek assistance from a professional plumbing company service. 

Feminine Hygiene and Baby Products  

Feminine hygiene products, including sanitary items and baby products, contain non-biodegradable cotton fibers. Proper disposal methods like responsible binning rather than flushing them down toilets are crucial. 

This practice not only upholds good hygiene but also prevents blockages. The fibers from these products tend to trap other waste materials, forming stubborn clogs that are difficult to clear once they’ve formed. 

Practical solutions involve installing drain strainers or guards to catch fibers before they enter pipes. In cases of persistent blockages, seeking professional plumbing company assistance ensures effective removal of stubborn clogs, maintaining a trouble-free plumbing system. 

Oil and Grease 

Blockages in kitchen pipes commonly stem from fat, grease, and oil residues. As kitchen sinks are where dirty dishes are washed, food waste often gets trapped in the pipelines. These substances are adhesive, and when a layer of fat or grease accumulates, it becomes a magnet for other waste materials, exacerbating the clog. 

While the bin is the ideal place for disposing of leftover food or waste, it is surprising how often items like steak trimmings, coffee grounds, tea leaves, vegetable oil, chocolate, cream, and various food scraps end up inside blocked pipes. 

Prevention and Solutions  

To manage minor oil residue in drains, dishwashing liquid can help disperse it. A mixture of boiling water and dishwashing detergent poured down the sink can assist in breaking down fat buildup. Alternatively, a natural cleaning remedy involving a combination of bicarbonate soda and vinegar can be used as well. 

Pipe Scales 

Even with diligent pipe maintenance, deterioration is inevitable over time, often due to pipe scaling. This occurs particularly in areas with high mineral content in water, leading to the accumulation of metallic deposits like calcium and magnesium, which disrupt the natural flow of water. 

In some cases, these mineral deposits have been known to impact the efficiency of appliances such as washing machines and dishwashers. 


To prevent scaling, consider installing water softeners, conducting regular maintenance checks, and employing scale inhibitors to minimize mineral deposits in pipes. 


Over time, pipes will naturally deteriorate, leading to potential sewage backup and the need for maintenance such as pipe relining or replacement. This is particularly prevalent in older homes with concrete, terracotta, or clay pipes.  

Erosion of the soil beneath the drainage lines can cause the pipes to sink, leading to joint breakage or even pipe fractures, especially in freezing temperatures. Even with modern, durable plastic pipes, changes in soil structure can contribute to their deterioration. 


The prevention of pipe disintegration involves regular inspections, especially in older homes with concrete, terracotta, or clay pipes. Early identification of deterioration allows for proactive measures. Stabilizing the soil around drainage lines through proper grading, landscaping, or retaining walls is crucial to prevent pipes from sinking due to soil erosion 


While tree roots are notorious for infiltrating pipes, they are not the only concern. Sticks, debris, dirt, and leaves can also contribute to pipe blockages, often making it difficult to identify the exact cause. 


A proactive measure involves maintaining a clean yard and ensuring proper disposal of waste in the trash, rather than allowing it to enter the sewer drain system, potentially causing clogs in the pipes.  

Household Objects  

Household items like jewelry, dental floss, and children’s toys occasionally find their way into pipelines, causing slow drainage or blockages deep within the pipes.  

In such cases, professional plumbers often use cameras to inspect the drains before conducting repairs. 


Hair often contributes to blocked drains in both kitchen sinks and bathrooms. While controlling hair loss is not feasible, maintaining regular sink and drain clearing routines helps maintain smooth water flow. When hair strands are amassed and entangled, they adhere to soap residue and other sticky substances, diminishing pipe diameter. 

Prevention and Solution 

Switching to soap-free washes and employing pressure cleaning methods effectively eliminates soap build-up in the lines. Drain cleaners containing sulfuric acid or drain snakes are useful for addressing resilient clogs like those caused by hair accumulation, as are drain screens for drain openings. Alternatively, enlisting a drain cleaning service equipped with pressure jet cleaning systems is a practical solution. 


Inadequate installation or construction of plumbing systems can result in drain blockages, often caused by errors in calculating the slope of sewer lines and water pipes. When the slope is incorrectly set, it hampers the smooth flow of waste. 


Ideally, drainpipes should have a standard pitch of ¼-inch per foot, enabling gravity to efficiently direct waste away from the house. This optimal slope ensures proper waste flow and helps prevent blockages within the plumbing system. 

Overloaded and Undersized Pipes 

Construction oversights often involve plumbers installing pipes that are smaller than necessary, leading to increased pipeline load. Depending on household needs and family size, opting for pipes larger than 4 inches in diameter may be essential for efficient plumbing supply. 

Signs of an overloaded pipeline include a stagnant septic system emitting foul odors or even bursts in the pipes, resulting in leakages. These indicators highlight the strain on the plumbing system, necessitating larger pipes to accommodate the flow adequately and prevent potential issues like foul odors or leaks. 

So, these are the common causes of clogged drains. Understanding these diverse array of plumbing issues is pivotal in safeguarding your home’s plumbing needs. Recognizing these culprits can empower you to adopt proactive measures for a hassle-free plumbing system. Regular inspections, strategic landscaping, and responsible waste disposal are essential preventive actions, ensuring a smoothly functioning plumbing network.
