Common Drain Blockage Myths: What Actually Works in 2025

At Mersey Rod, we’ve seen every kind of drain blockage imaginable. Over the years, we’ve also heard plenty of myths about what supposedly works to clear them, and we bet that you have as well! Unfortunately, many of these so-called ‘solutions’ can do more harm than good. In 2025, it’s time to set the record straight and share some seasonal tips to maintain drainage that actually work when it comes to keeping your drains clear.

Common Drain Blockage Myths

Myth 1: Chemical Drain Cleaners Are the Best Fix

Many people believe that pouring a chemical drain cleaner down the sink will instantly dissolve any blockage. While these products may provide temporary relief, the truth is they often cause more damage in the long run. The harsh chemicals can corrode pipes over time, leading to leaks and expensive repairs. Instead, try using a plunger or a drain snake to break up blockages. If the problem persists, it’s best to call in the professionals to assess the situation properly.

Myth 2: Boiling Water Will Solve Any Blockage

Pouring hot water down a drain can sometimes help clear minor grease build-ups, but it’s one of the most common drain blockage myths that this solution is a one-size-fits-all solution. For tougher clogs, particularly those caused by hair or foreign objects, hot water alone won’t do much. In some cases, it can even make the problem worse by softening fats and allowing them to coat the pipes further. Mechanical methods, such as plunging or drain rods, are often more effective.

Myth 3: Drain Blockages Only Happen in the Kitchen

Many people assume that blockages only occur in kitchen sinks due to food waste and grease. However, bathrooms are just as prone to clogging. Hair, soap scum, and even small objects like cotton buds can create significant drainage problems over time. Regularly cleaning bathroom drains and using hair catchers can prevent many of these issues before they become serious blockages.

Myth 4: Baking Soda and Vinegar Are a Miracle Cure

A popular internet hack involves using baking soda and vinegar to clear drains. While this fizzy reaction might look promising, it doesn’t have the power to break down stubborn blockages. In some cases, it can even create a sludgy mess that worsens the clog. If your drain is slow or completely blocked, it’s best to use a drain snake or call a professional rather than relying on ineffective home remedies.

Myth 5: Drain Blockages Always Happen Suddenly

Another of the most common drain blockage myths is that clogs happen instantly, but in reality, most develop over time. A slow build-up of grease, hair, and other debris can restrict water flow long before a complete blockage occurs. If you notice slow drainage, gurgling sounds, or foul odours, don’t ignore them—these could be early warning signs of a clog forming. Regular maintenance and prompt action can prevent more severe problems down the line.

Myth 6: Flushable Wipes Are Safe for Drains

One of the biggest modern-day myths is that so-called ‘flushable’ wipes are completely safe for your plumbing. The truth is that these wipes don’t break down as easily as toilet paper and can quickly accumulate in pipes, leading to stubborn blockages. Over time, they can combine with grease and other debris, forming massive clogs in the sewer system. The best practice is to dispose of wipes in the bin rather than down the toilet to avoid costly plumbing problems.

Quick Tips to Prevent Drain Blockages

Now that we’ve debunked these common myths, here are some practical steps you can take to prevent blockages in your home:

• Dispose of Grease Properly: Never pour fats, oils, or grease down the sink. Instead, collect them in a container and throw them in the bin once solidified.
• Use Drain Covers: Hair, food particles, and soap scum are common culprits for clogs. A simple drain cover can help trap these before they cause issues.
• Be Mindful of What You Flush: Only flush toilet paper and human waste—anything else, including wipes and sanitary products, should go in the bin.
• Regular Maintenance: Periodically flushing drains with hot water can help keep them clear, and scheduling a professional drain inspection can catch potential problems early.

When to Call in the Professionals

While DIY methods can sometimes work for minor clogs, there are times when professional help is necessary. Here are a few situations where you should pick up the phone and call Mersey Rod, one of the top Liverpool drain unblocking companies:

• Recurring Blockages: If your drains keep clogging, it’s likely there’s a deeper issue that needs expert attention.
• Multiple Drains Are Blocked: If more than one drain is affected, the problem could be in your main sewer line.
• Slow Drainage Despite DIY Attempts: If you’ve tried everything and water is still draining slowly, it’s time to get a professional assessment.
• Foul Smells Coming from Drains: Persistent odours could indicate a more serious problem, such as a broken pipe or a build-up of waste in your drainage system.
• Overflowing or Backing Up Water: If water is coming back up through sinks or toilets, this is a clear sign of a serious blockage that needs immediate professional attention.
