7 Plumbing Myths That Could Cost You Money

We’ve heard our fair share of plumbing myths over the years. When myths masquerade as truths, they can quietly drain your wallet and wreak havoc on your home. 

These kinds of myths are often spread by word-of-mouth and stick because they seem harmless or make quick fixes sound like the smarter option. 

Don’t worry; we’re here to save you from the horror of falling for these false beliefs. Let’s pull back the curtain on the seven most common plumbing myths that could be costing you more than you realise.

Myth #1: A Leaky Tap Isn’t a Big Deal

One of the most common plumbing myths is that a leaky tap isn’t worth fixing. After all, it’s just a drip, right? 

However, that gentle, rhythmic sound might seem harmless, but it can eventually lead to significant water waste and higher bills. A single dripping tap can actually waste over 5,000 litres of water a year. That’s enough to fill a small swimming pool!

Persistent leaks can also cause damage to your fixtures and promote mould growth. Water seeping into cabinets or walls can lead to rot and structural issues that can turn into a major repair job over time.

Our team at Rowlen often finds that what appears to be a simple leak is sometimes a symptom of a larger issue, such as high water pressure or corroded pipes. Addressing these problems early can save you from more extensive – and expensive – repairs down the line.

Myth #2: All Plumbers Are the Same

Not all plumbers are created equal. 

While many may offer similar services, the quality, expertise, and certifications can vary widely. Choosing the right professional is key to protecting your home and keeping systems running smoothly.

At Rowlen, all our local plumbers hold a City & Guilds certification, making them fully qualified and recognized for their competence in plumbing and heating systems.

Plus, they are also Gas Safe registered, signifying that our team is qualified to work safely and legally on all gas appliances.

Why Qualifications Matter

Plumbers with a City and Guilds certification demonstrate more competence in the industry. It also allows them to work on wider concerns and more plumbing issues.

On the other hand, Gas Safe registration is a legal requirement for anyone working with gas appliances in the UK, including your heating systems. It ensures that the plumber has undergone rigorous training and assessments to handle gas safely.

Hiring someone without these certifications can lead to dangerous consequences, including gas leaks, improper pipework installation, and even explosions. 

Moreover, work done by unregistered individuals may void your home insurance and appliance warranties.

Myth #3: You Can Use Chemical Drain Cleaners Regularly

Not-so-fun fact: These harsh chemicals can corrode older plumbing systems, leading to leaks and costly repairs.

Relying on chemical drain cleaners regularly is one of those persistent plumbing myths that does more damage than good. Moreover, they often provide only a temporary solution, failing to address the root cause of the blockage. 

Over time, this can result in recurring clogs and more severe plumbing issues.

Safer, Long-Term Alternatives We Recommend

Instead of reaching for chemical cleaners, consider mechanical methods like drain snakes or plungers. These tools can effectively remove blockages without harming your pipes. 

You might have heard that boiling water clears drains, but it only works for very minor blockages – and even then, it’s no substitute for proper cleaning or expert advice.

Another way of safely unclogging your drains actually makes use of things you can find in your kitchen. Using vinegar and baking soda for pipes is a safer and more natural method to help break down grime without corroding your plumbing. 

Additionally, being mindful of what goes down your drains can prevent clogs from forming in the first place. 

This includes avoiding grease, coffee grounds, hair, and flushable wipes and tissues! In fact, one of the very damaging myths about flushing wipes is that they’re labelled “flushable,” even though they can totally clog your drains.

When in doubt, our team at Rowlen is always ready to assist with professional, safe, and effective drain-cleaning solutions, as one of our eco-friendly plumbing practices.

Myth #4: Plumbing Issues Will Fix Themselves

Believing that plumbing issues fix themselves is another example of how plumbing myths can lead to more trouble and even more costly consequences. 

Common Small Issues That Turn Costly

Dripping taps, running toilets, and low water pressure might not seem urgent, but they often hide deeper issues. 

  • Low pressure could signal leaks or corrosion.
  • A slow-draining sink might indicate a developing clog.
  • Strange noises in your pipes could mean airlocks or pressure issues. 
  • A running toilet that you ignore can waste hundreds of litres of water daily. 

To maintain a healthy plumbing system, always leave a budget for regular inspections and immediate repairs.

Myth #5: DIY Fixes Save Money

While DIY projects can be satisfying, plumbing repairs often require professional expertise. 

Videos make it look easy, but many DIY plumbing dangers can make leaks worse, causing flooding, or even creating gas hazards. 

For instance, improperly installed water heaters can pose serious risks, including scalding and explosions. Similarly, attempting to fix a gas boiler without proper training can result in gas leaks or carbon monoxide poisoning.

When to Call In Professional Help

If you’re experiencing recurring issues, such as frequent clogs or inconsistent water temperatures, it’s time to call in the experts. Our team at Rowlen is equipped with the knowledge and tools to diagnose and fix problems efficiently and safely.

Myth #6: You Don’t Need Regular Boiler Servicing

Out of sight shouldn’t mean out of mind. Regular boiler servicing keeps your home warm and your system reliable, saving you from unexpected heating and plumbing issues.

Neglecting annual maintenance can lead to undetected issues, reduced performance, and higher energy bills. In some cases, it might even void your warranty.
