Plumbing is one of those areas where myths spread quickly—often passed down through households as “common knowledge” but rarely based on actual fact. These misconceptions can lead to costly repairs, unnecessary damage, or even long-term issues that could have been easily avoided.
Whether you’re a homeowner, renter, or property manager, understanding the truth behind everyday plumbing myths can help you protect your home and make informed decisions when issues arise. And when in doubt, relying on a qualified professional such as Plumbform ensures you’re getting accurate advice backed by experience.
Below, we break down some of the most common plumbing myths—and what you should be doing instead.
Myth 1: “It’s Fine to Flush Wipes Marked as ‘Flushable’”
Despite clever marketing, most “flushable” wipes don’t break down quickly enough in water. They can accumulate in your pipes, cling to other debris, and create blockages that are costly to clear. Even if they disappear from sight when flushed, they often cause problems further down the line.
The truth: The only things that should go down your toilet are the three P’s—pee, poo, and paper. Everything else belongs in the bin.
Myth 2: “A Slow Drain isn’t a Big Deal”
A sluggish drain may seem like a minor annoyance, but it’s often the early warning sign of a developing clog, pipe obstruction, or build-up of soap scum, hair, or grease. Ignoring this issue can lead to complete blockages or even pipe damage.
The truth: Slow drainage should be addressed promptly. Early intervention saves money and prevents messy overflows.
Myth 3: “Hot Water Melts Grease and Makes It Safe to Pour Down the Sink”
This is one of the most common and costly misconceptions. Hot water may liquefy grease temporarily, but the moment it cools inside your pipes, it solidifies—and combines with other debris to form thick, stubborn blockages.
The truth: Grease should never go into your sink. Instead, let it cool and dispose of it in the bin.
Myth 4: “DIY Fixes are Just as Good as Professional Work”
Online tutorials make plumbing look deceptively simple, tempting many homeowners to tackle repairs themselves. However, a small mistake—using the wrong fitting, overtightening a connection, or misdiagnosing an issue—can create far bigger problems.
The truth: While simple tasks like replacing a showerhead are manageable, most plumbing jobs require specialised tools, licensing, and expertise. When in doubt, call a qualified plumber.
Myth 5: “Leaky Taps Aren’t Urgent”
A dripping tap may not seem like an emergency, but it wastes a surprising amount of water over time and can indicate worn-out parts or pressure issues. Left unattended, it can also lead to corrosion or damage within the tap mechanism.
The truth: Fixing a leak promptly saves water, reduces bills, and protects your fixtures.
Myth 6: “Boiling Water Clears All Clogs”
Boiling water can help dissolve small soap or grease build-ups, but it won’t remove solid obstructions like hair, wipes, or mineral deposits. In some cases—especially with PVC pipes—it can even cause damage.
The truth: Treat boiling water as a light maintenance option, not a cure-all. Persistent clogs require proper tools or professional help.
Myth 7: “If Water Is Flowing, Your Pipes Are Fine”
Just because water still runs doesn’t mean your plumbing system is in good condition. Hidden leaks, partial blockages, tree root invasions, and deteriorating pipes can continue to worsen quietly behind walls or underground.
The truth: Regular plumbing inspections can catch issues early, preventing major repair costs.
Myth 8: “Store-Bought Chemical Cleaners Are Safe and Effective”
Chemical drain cleaners may promise quick fixes but can be harsh on your pipes, leading to corrosion and long-term damage. They also pose risks for septic systems and can be harmful if inhaled or handled incorrectly.
The truth: Mechanical solutions (like plungers or drain snakes) or professional-grade cleaning equipment offer safer, long-lasting results.
Myth 9: “Plumbing Fixtures Don’t Need Maintenance”
Many people assume taps, toilets, and hot water systems will keep functioning smoothly without any upkeep—but like any system in your home, they require occasional checks and servicing.
The truth: Routine maintenance helps extend the life of your fixtures, improves performance, and prevents sudden breakdowns.
Final Thoughts
Plumbing myths often arise from well-meaning advice or outdated information, but believing them can lead to significant inconvenience—and even property damage. By understanding what’s true and what’s not, you can take better care of your home’s plumbing system and avoid unnecessary headaches.
