When it comes to plumbing, everyone has heard a bit of “helpful advice” passed down from family, friends or online sources. The problem? A lot of these so called tips are actually myths and following them can end up costing you time, money and major plumbing repairs. At The Great Plumbing Co., we’ve seen the damage these myths can cause. So we’re breaking down the most common plumbing misconceptions and giving you the expert truth behind them.
Myth #1: “Hot water melts grease, so it’s safe to pour it down the drain.”
The truth:
Hot water does melt grease but only temporarily. Once the melted grease travels farther down your plumbing and cools, it solidifies again, sticking to the inside of your pipes. Over time, that buildup attracts food particles and debris, which eventually leads to clogs and slow drains.
What to do instead:
Let grease cool and harden, scrape it into the garbage and wipe pans before washing. It’s easier on your plumbing and your wallet.
Myth #2: “A running toilet is no big deal.”
The truth:
A running toilet is one of the most common and most ignored plumbing problems in homes. But what seems small can waste thousands of litres of water a year, drastically increasing your water bill. Most running toilets are caused by a worn flapper or faulty fill valve. Both are inexpensive parts, but leaving the issue unresolved for too long can eventually damage internal components or lead to overflowing.
The takeaway:
If a toilet runs for more than a minute after flushing, it needs attention
Myth #3: “Flushable wipes are actually flushable.”
The truth:
The word “flushable” is misleading. While wipes may go down the toilet, they don’t break down like toilet paper. Instead, they stay intact, collecting in your pipes or the sewer system and causing major blockages. Cities across North America spend millions dealing with massive “fatbergs” made from wipes, grease, and debris.
Better solution:
Only flush toilet paper. Dispose of wipes in the trash.
Myth #4: “All plumbers are the same, I should just pick the cheapest.”
The truth:
Plumbing is one of those trades where skill, experience and professionalism matter. The cheapest option might save you money upfront, but poor workmanship or incorrect installation can lead to leaks, water damage and costly repairs later. Look for plumbers who are licensed, insured, reputable and come with reliable customer reviews. Cheap can be very expensive in the long run.
Myth #5: “A dripping faucet isn’t worth worrying about.”
The truth:
A single dripping faucet can waste up to 3,000 litres of water per year. Beyond the waste, a persistent drip also means something is worn often a washer, seal, or valve. Ignoring it can strain the faucet assembly and lead to bigger issues or total fixture failure. Fixing a drip is usually quick and inexpensive and saves water.
Myth #6: “Ice cubes sharpen garbage disposal blades.”
The truth:
Garbage disposals don’t actually have sharp blades. They use blunt impellers to grind food against a stationary grind plate.
Ice won’t sharpen anything but it can help clear debris and freshen a smelly disposal. So the myth is partly true in effect, but not in reason. Just don’t expect ice to solve major disposal problems.
Myth #7: “It’s normal for water heaters to make noise.”
The truth:
A little noise is normal, but banging, popping, or rumbling usually means sediment has built up at the bottom of the tank. This forces the water heater to work harder, reducing efficiency and shortening its lifespan.If your water heater sounds like it’s boiling rocks, it’s time for a professional flush or inspection.
Myth #8: “Chemical drain cleaners are safe and effective.”
The truth:
Chemical drain cleaners may work in the moment, but they can corrode your pipes, damage rubber components, and kill beneficial bacteria in septic systems. They’re also harmful to the environment and dangerous if mixed with other substances.
Safer options:
Use a plunger, an enzyme-based drain treatment or call a professional for proper clearing.
Myth #9: “All low water pressure problems are due to the city’s supply.”
The truth:
While city issues can cause low pressure, most problems start inside the home. Mineral buildup, closed shutoff valves, leaking pipes, clogged aerators, or failing pressure regulators are common culprits. If pressure has suddenly dropped, it’s worth investigating it could even indicate a hidden leak.
Myth #10: “You don’t need a plumbing inspection before buying a home.”
The truth:
Plumbing problems are often hidden behind walls or underground, making them easy to miss during a regular home inspection. Issues like aging pipes, root intrusion, sewer line blockages, or outdated fixtures can cost thousands after move-in.
A professional plumbing inspection gives you peace of mind and negotiating power.
