Blocked Drains: The Signs, Causes, and Solutions

Blocked drains can be a nuisance and cause significant damage to your property if not addressed promptly. But how do you know if your drains are blocked? What are the common causes of blocked drains? And most importantly, how can you fix them? In this comprehensive guide, we will answer all these questions and more to help you effectively deal with blocked drains and avoid costly repairs.

Signs of Blocked Drains

Blocked drains can manifest in various ways, and it’s essential to recognize the signs early to prevent further damage. Some common indicators of blocked drains include:

  • Slow draining water: If your sink, bathtub, or shower is taking longer than usual to drain, it could be a sign of a blockage in your pipes.
  • Unpleasant odors: Foul smells coming from your drains can indicate a buildup of waste in your pipes.
  • Gurgling noises: If you hear strange noises coming from your drains, it could be a sign of trapped air caused by a blockage.
  • Raised water levels: If the water level in your toilet rises higher than usual after flushing, it could be due to a blocked drain.
  • Overflowing drains: If water is overflowing from your drains, especially during heavy rainfall, it could be a sign of a blockage in your drainage system.

Common Causes of Blocked Drains

Blocked drains can result from various factors, including:

  • Hair: Hair is a common culprit for clogged drains, as it can easily become tangled and trapped in your pipes.
  • Grease and fat: Cooking grease and fat can solidify in your pipes, leading to blockages.
  • Food waste: Food scraps and particles can accumulate in your pipes and cause blockages.
  • Foreign objects: Items such as sanitary products, baby wipes, and small toys can become lodged in your pipes, leading to blockages.
  • Tree roots: Tree roots can infiltrate your drainage system, causing blockages and damage to your pipes.
  • Broken or damaged pipes: Cracked or broken pipes can cause blockages and disrupt the flow of water through your drainage system.

Solutions for Blocked Drains

If you suspect a blocked drain, there are several solutions you can try to clear the blockage:

  • Plunger: A plunger can help dislodge minor blockages by creating suction and forcing the obstruction to move.
  • Chemical drain cleaner: Chemical drain cleaners can break down and dissolve blockages in your pipes. However, use these products with caution, as they can be harmful to your pipes and the environment.
  • Drain snake: A drain snake, also known as an auger, can help remove blockages by breaking up and retrieving the obstruction.
  • Hydro jetting: Hydro jetting involves using high-pressure water to blast away blockages in your pipes. This method is best left to professionals, as it requires specialized equipment and can potentially damage your pipes if not done correctly.

Preventing Blocked Drains

Prevention is always better than cure, and there are several steps you can take to minimize the risk of blocked drains:

  • Install drain guards: Drain guards can help catch hair, food waste, and other debris before they enter your pipes.
  • Dispose of grease and fat properly: Instead of pouring grease and fat down your sink, collect them in a container and dispose of them in the trash.
  • Be mindful of what you flush: Only flush toilet paper and human waste down your toilet. Avoid flushing sanitary products, baby wipes, and other items that can cause blockages.
  • Regularly clean your drains: Regularly cleaning your drains with a mixture of hot water, baking soda, and vinegar can help prevent buildup and blockages.

When to Call a Professional

While some blocked drains can be resolved with DIY methods, there are instances when it’s best to call a professional plumber:

  • Persistent blockages: If you’ve tried multiple methods to clear your blocked drain without success, it’s time to call a professional.
  • Overflowing drains: Overflowing drains can indicate a more severe issue with your drainage system, and a professional plumber can help diagnose and resolve the problem.
  • Damaged pipes: If you suspect broken or damaged pipes, it’s essential to call a professional to assess and repair the damage.

Causes of Blocked Drains

Blocked drains can cause many problems, such as slow water flow, foul odors, and even flooding. But what causes blocked drains, and how can you prevent them? In this article, we will explore the most common causes of blocked drains and provide tips on how to prevent them. By understanding these causes and taking preventative measures, you can save yourself the hassle of dealing with blocked drains and the potential damage they can cause.

1.       Foreign Objects and Debris

One of the most common causes of blocked drains is the accumulation of foreign objects and debris. These can include items such as toilet paper, wipes, diapers, and sanitary products that should not be flushed down the toilet. Food scraps, coffee grounds, and other debris can also cause blockages when they are washed down the sink or disposed of in a garbage disposal unit. To prevent blocked drains caused by foreign objects and debris, avoid flushing anything other than toilet paper down the toilet and use a sink strainer to catch any food particles.

2.       Grease and Fat Buildup

Grease, fat, and oil are notorious for causing drain blockages. They can solidify as they cool down, sticking to the walls of the pipes and eventually forming a hard blockage. You can prevent grease and fat buildup in your drains by being mindful of what you wash down the sink. Instead of pouring grease and oil directly down the sink, allow it to cool and solidify, then scrape it into the trash. You can also use a grease trap or interceptor to help catch and collect grease before it enters your drainage system.

3.       Hair and Personal Care Products

Hair and personal care products are another common cause of blocked drains, particularly in the bathroom. Hair can become tangled and build up over time, creating a blockage that prevents water from draining properly. Personal care products such as soap, shampoo, and conditioner can also contribute to drain clogging by sticking to the walls of the pipes. To prevent hair and personal care product blockages, clean hair from shower and sink drains regularly and consider using a drain cover to catch hair before it enters the pipes.

4.       Tree Roots and Plant Debris

Tree roots can infiltrate your drainage system, causing blockages, pipe damage, and even collapsed pipes. Roots are attracted to the moisture and nutrients found in sewer lines and can grow through small cracks or joints in the pipes. Over time, tree roots can cause significant damage and blockages in your drainage system. Plant debris, such as leaves and twigs, can also accumulate in outdoor drains, causing blockages. To prevent tree root and plant debris blockages, keep an eye on the trees and plants near your drainage system and consider professional root removal if necessary.

5.       Pipe Damage and Misalignment

Damaged or misaligned pipes can cause blocked drains by creating areas where debris and other materials can become trapped. Pipe damage can be caused by a variety of factors, including ground movement, tree root infiltration, and corrosion. If you suspect you have damaged or misaligned pipes, it’s important to address the issue as soon as possible to prevent further damage and potential blockages. Contact a professional plumber to assess and repair any damaged or misaligned pipes.

6.       Poor Drainage Design

Poor drainage design can also contribute to blocked drains. If your drainage system is not designed to handle the volume of water and waste flowing through it, you may experience more frequent blockages. Inadequate pipe size, improper pipe slope, and lack of venting can all contribute to poor drainage design. If you believe your drainage system may be poorly designed, consult a professional plumber to help identify and address the issue.

7.       Seasonal Changes

Seasonal changes can cause blocked drains in a variety of ways. In the fall, leaves and other plant debris can accumulate in outdoor drains, causing blockages. In winter, freezing temperatures can cause pipes to freeze and burst, leading to blockages and other damage. To prevent seasonal drain blockages, be sure to clear outdoor drains of debris regularly and take steps to protect your pipes from freezing during cold weather.

8.       Preventative Measures and Maintenance

Preventing blocked drains is much easier than dealing with the aftermath of a blockage. By following these preventative measures and performing regular drain maintenance, you can help keep your drains flowing freely:

  • Use a sink strainer to catch food particles and other debris
  • Avoid flushing anything other than toilet paper down the toilet
  • Properly dispose of grease and oil by scraping it into the trash
  • Clean hair from shower and sink drains regularly
  • Keep an eye on trees and plants near your drainage system
  • Schedule regular drain cleaning and maintenance with a professional plumber
