Common Causes of Clogged Drains 

Having a clogged drain can be a frustrating experience. It can disrupt your daily routine and lead to unpleasant odors in your home. Understanding the common causes of clogged drains can help you prevent these issues and ensure the smooth functioning of your plumbing system. In this blog post, we will discuss some of the most common causes of clogged drains and when it’s necessary to hire a plumber to fix them. 

1. Hair and Soap Scum Buildup

One of the primary culprits behind clogged drains is the accumulation of hair and soap scum. Over time, these substances can accumulate in your drains, forming a sticky residue that traps other debris and prevents water from flowing freely. To avoid this, use a drain strainer in your sink and shower to catch loose hair before it goes down the drain. Regularly cleaning your drains with a mixture of baking soda and vinegar can also help prevent hair and soap scum buildup. 

2. Food Waste

Another common cause of clogged drains is food waste. Some smaller food particles may accidentally end up in the sink, leading to a gradual buildup in the pipes. Fatty or greasy foods are particularly problematic as they can solidify and stick to the inside of the pipes, narrowing the diameter and causing clogs. To prevent this, use a sink strainer to catch food particles, and avoid pouring grease or oil down the drain. Instead, dispose of them in a separate container and throw them in the trash. 

3. Foreign Objects 

Sometimes, objects that aren’t meant to be flushed or washed down the drain find their way into our plumbing system. This can include items such as dental floss, cotton swabs, baby wipes, paper towels, or children’s toys. These items can get stuck in the pipes, obstructing water flow and leading to clogs. To prevent foreign objects from causing drain blockages, be mindful of what you dispose of in the sink or toilet. 

4. Tree Root Intrusions

In some cases, clogs can occur due to tree root intrusions in underground pipes. Tree roots are constantly seeking sources of water and nutrients, and if there’s a small crack or joint in your sewer lines, they can infiltrate and cause blockages. Signs of tree root intrusions include slow draining toilets, gurgling sounds, or foul odors coming from your drains. If you suspect tree root intrusions, it’s crucial to call a professional plumber as soon as possible to assess and repair the issue. 

When to Hire a Plumber to Fix a Clogged Drain

While some minor drain clogs can be resolved using DIY methods or commercial drain cleaners, there are certain instances where it’s best to hire a professional plumber. Here are a few signs that indicate it’s time to call in the experts: 

1. Persistent Clogs

If you’ve tried all the usual methods to unclog your drain – plungers, drain snakes, or chemical cleaners – and the problem keeps coming back, it’s likely a sign of a more severe underlying issue. This could include a blockage deep within the pipes or a damaged sewer line. In such cases, it’s best to hire a plumber who has the tools and expertise to diagnose and fix the problem. 

2. Multiple Clogged Drains

If you have multiple drains throughout your home that are clogged simultaneously, it could be an indication of a larger plumbing issue. This can happen when there is a blockage in the main sewer line, causing backups in various drains. Professional plumbers have the knowledge and equipment to identify and resolve problems affecting the entire plumbing system effectively. 

3. Foul Odors or Water Backups

If you notice foul odors coming from your drains or experience water backups, it’s vital to seek professional assistance. These signs can indicate a more significant problem, such as a damaged sewer line or a blockage that requires immediate attention. Ignoring these symptoms can lead to more extensive damage and costly repairs down the line. 


Some of the most common causes of clogged drains include hair and soap scum buildup, food waste, foreign objects, and tree root intrusions. By taking preventive measures and being cautious about what goes down your drains, you can minimize the risk of clogs. However, if you encounter persistent clogs, multiple clogged drains, foul odors, or water backups, it’s advisable to hire a plumber to fix the issue promptly. Remember, timely intervention can help prevent further damage to your plumbing system and save you from unnecessary expenses.
