🛠️ Plumbing Myths vs. Facts: What Every Homeowner Should Know
From lemon peels in your garbage disposal to running toilets “fixing themselves,” let’s set the record straight on some of the most common plumbing misconceptions.

Introduction
When it comes to plumbing, there’s no shortage of bad advice floating around—some of it passed down from well-meaning family members, others from the depths of internet forums.
The problem? Following the wrong advice can lead to costly damage, water waste, or even voided warranties.
In this article, we bust some of the most common plumbing myths homeowners in Cambridge, ON should stop believing—and share the facts to keep your home in good shape.
1. Myth: Lemons Clean Your Garbage Disposal 🍋
Fact: Lemons make it smell better, but they don’t clean it.
Tossing lemon peels in your garbage disposal will freshen the scent, but citrus oils can corrode rubber seals and dull the blades over time. For actual cleaning, use ice cubes and vinegar or baking soda with hot water.
2. Myth: A Brick in the Toilet Tank Saves Water 🚽
Fact: It can cause poor flushing and damage the toilet
This old trick might reduce water per flush, but it can also lead to incomplete flushing, multiple flushes, and damage to the internal components. Modern low-flow toilets are designed to conserve water without hacks.
3. Myth: If Water Is Draining, the Pipe’s Not Clogged
Fact: Draining water doesn’t mean the pipe is clear.
Even with partial blockages, water can still get through. But over time, buildup from grease, soap scum, hair, or mineral deposits can worsen, causing full clogs and backups—especially in older homes in Cambridge.
4. Myth: All Plumbers Are the Same
Fact: Licensing, experience, and service quality matter.
Anyone can call themselves a plumber, but only licensed professionals can guarantee safe, code-compliant work. Look for companies (like Reliant Plumbing) that are insured, local, and reputable.
5. Myth: Running Toilets Fix Themselves Over Time
Fact: They only waste more water the longer you wait.
A running toilet can waste hundreds of litres of water a day. It's usually caused by a worn flapper, faulty fill valve, or a misaligned float—and it won't stop on its own. Fixing it early saves water and your wallet.
6. Myth: Chemical Drain Cleaners Are Safe and Effective
Fact: They can corrode pipes and often don’t work.
Those over-the-counter chemical cleaners can damage older plumbing, especially in Cambridge homes with cast iron or copper pipes. They also often push the clog deeper instead of removing it. Stick with a plunger, snake, or call a pro.
7. Myth: Minor Leaks Aren’t a Big Deal
Fact: A “tiny drip” can turn into a major issue.
What looks like a small leak can lead to mold, rot, and water damage over time. Even slow leaks behind cabinets or walls can result in expensive repairs and reduced water pressure.
8. Myth: You Don’t Need to Worry About Plumbing Until Something Breaks
Fact: Preventive maintenance is key.
By the time a pipe bursts or a fixture fails, the damage is already done. Annual inspections, drain cleaning, and checking for corrosion can help avoid surprises and extend the life of your plumbing system.

Misinformation can lead to costly mistakes and avoidable damage. Knowing the facts—and ignoring the myths—can keep your home’s plumbing running smoothly for years.
