What Are the Five Common Causes of Drainage Blockages

Drainages are one of the crucial components of an efficient and fully functioning plumbing system. They remove the wastewater from your home’s sinks, showers, and toilets. 

Being a responsible homeowner means ensuring your drainage systems remain free from blockages. While clogged drains are a common problem for most homeowners, they can be time-consuming and costly if you don’t call drainage plumbing services immediately. 

Besides regularly cleaning and maintaining your drains, you must also understand why these issues occur. This article will enumerate the five common causes of clogged drainage to help ensure its best condition and reduce repair costs. 

1. Damaged Pipes 

Pipes are an integral part of any fully-functioning property. They’re responsible for transporting from one place to another. However, it can eventually wear out, especially if you don’t maintain them properly or have an aging piping system. 

These faulty pipes can cause a blocked drain. It can also lead to expensive repairs and collapse if the previous contractors installed them poorly or tree roots are creeping into the plumbing system. 

For this reason, it’s always crucial to call a professional drainage plumbing company immediately. Otherwise, your home will suffer more expensive mistakes and hazardous health risks. 

2. Improper Installation

More homeowners are investing in “Do it Yourself” projects because they think they can save more money. Unfortunately, these led to several issues, especially with their plumbing systems. 

While it can spare them from spending money on hiring a professional drainage plumbing company, poorly installed drainage pipes and inadequate plumbing can cause collateral damage to other parts of their home. You can prevent these expensive mistakes by selecting only the highest quality pipes and contacting your local plumber to install them. 

3. Water Flow Issues 

A functioning drainage ensures the water flows downwards. Whether you install it yourself or hire a professional drainage plumbing company, see that the slope is adequately angled so dirt and debris won’t cause a blockage. It’s also worth taking some time to educate yourself about the other causes of a clogged drain. 

Fortunately, in some cases, you can easily spot signs of an impending major drainage issue, such as strange noises from your toilet, unpleasant odours from your drain, and water buildup on your sink after use. While you can quickly resolve some issues with a plunger, other severe problems warrant a call for professional help. 

4. Foreign Objects 

A drainage blockage occurs when foreign objects like hair, food, soap, and fats build up between the drain pipe and other pipes. As they gradually increase, they will hinder the proper water flow, causing a clog in the drainage system. It’s a common issue in toilets where people flush toilet paper and other sanitary items. 

You can prevent this embarrassing and expensive mistake by practising caution when throwing things in your sink, toilet, bathtub, and drain pipes. Ensure only water will enter the drain when washing your hair and dishes and disposing of kitchen waste. You can also call a drainage plumbing company to inspect your drainage system regularly. 

5. Heavy Storms and Rain

After heavy rain or an intense storm, your outdoor drains may clog because of the leaves and dirt trapped in them. This issue can lead to significant water buildup and flooding outside your property. 

You can prevent this expensive mistake by cleaning them and replacing all broken parts immediately. 


Being a responsible homeowner means ensuring your drainage system is free from damage and blockages. Regular maintenance and working with a professional drainage plumbing company can save you from expensive mistakes.
