Top 15 Plumbing Myths Texas Homeowners Still Believe (And the Truth Behind Them)
When it comes to home maintenance, few topics are surrounded by more misinformation than plumbing. From DIY shortcuts to outdated advice passed down for generations, plumbing myths can cost Texas homeowners thousands of dollars in unnecessary repairs.
In Central Texas—where hard water, shifting soil, high municipal water pressure, and extreme weather events all impact plumbing systems—believing the wrong advice can be especially risky.
At Neighborhood Plumbing & Drain, we’ve seen firsthand how common plumbing myths lead to burst pipes, slab leaks, failed water heaters, and expensive emergency repairs. Let’s break down the top 15 plumbing myths Texas homeowners still believe—and the truth behind them.
1. “If It’s Draining, It’s Fine”
The Myth: As long as water goes down, your drain is healthy.
The Truth: Slow drains are early warning signs.
In Central Texas, hard water mineral buildup is common. Over time, scale accumulates inside pipes, narrowing the flow path. If ignored, that slow drain can turn into a complete blockage—or even a sewer backup.
Routine drain cleaning prevents bigger issues later.
2. “Flushable Wipes Are Safe for Toilets”
The Myth: If the package says flushable, it’s plumbing-safe.
The Truth: They don’t break down like toilet paper.
Even wipes labeled “flushable” can cause clogs in residential sewer lines. In older neighborhoods around Lakeway, Georgetown, and Austin, aging sewer systems are particularly vulnerable to buildup from wipes.
Stick to toilet paper only.
3. “A Leaky Faucet Isn’t a Big Deal”
The Myth: It’s just a drip.
The Truth: Small leaks waste thousands of gallons annually.
A single dripping faucet can waste hundreds of gallons per month. Beyond water waste, leaks increase mineral deposits and wear down fixtures faster—especially with Texas’ hard water conditions.
4. “Hot Water Dissolves Grease in Drains”
The Myth: Run hot water after pouring grease down the sink.
The Truth: Grease cools and solidifies further down the line.
It may appear to wash away, but once grease cools in your pipes, it sticks to walls and traps debris—creating stubborn clogs. Always dispose of grease in the trash.
5. “Water Pressure Should Be as High as Possible”
The Myth: Stronger pressure is better.
The Truth: High pressure damages plumbing systems.
Many Central Texas homes experience municipal water pressure above 80 PSI. That may feel great in the shower—but it strains pipes, water heaters, appliances, and fittings.
The ideal range is 60–70 PSI. Anything higher may require a pressure reducing valve (PRV).
6. “Tankless Water Heaters Don’t Need Maintenance”
The Myth: Tankless means maintenance-free.
The Truth: Hard water requires annual flushing.
In areas like Lakeway and Bee Cave, mineral-rich water can quickly scale tankless heat exchangers. Annual descaling keeps systems efficient and prevents premature failure.
7. “Chemical Drain Cleaners Are Safe”
The Myth: Store-bought cleaners are harmless.
The Truth: They corrode pipes over time.
Most chemical cleaners contain harsh substances that weaken pipes—especially older copper or galvanized lines. Professional hydro jetting or mechanical snaking is far safer.
8. “All Plumbers Are the Same”
The Myth: Price is the only difference.
The Truth: Licensing, experience, and local knowledge matter.
Texas plumbing codes vary by municipality, and Central Texas soil conditions require specialized knowledge. Hiring a licensed, local professional ensures proper installation and long-term reliability.
9. “Ice Cubes Sharpen Garbage Disposal Blades”
The Myth: Ice sharpens disposal blades.
The Truth: Disposals don’t have traditional blades.
They use impellers to grind food waste. Ice can help clean buildup, but it doesn’t “sharpen” anything.
10. “A Water Heater Will Last Forever”
The Myth: If it still heats water, it’s fine.
The Truth: Most water heaters last 8–12 years.
Sediment buildup is accelerated by Texas hard water. Regular flushing extends lifespan and improves efficiency.
11. “You Don’t Need a Plumbing Inspection Unless There’s a Problem”
The Myth: No symptoms means no issues.
The Truth: Preventive inspections catch hidden leaks and pressure problems early.
Routine plumbing inspections can identify slab leak risks, high PSI, aging water heaters, and sewer line issues before they become emergencies.
12. “Brick Homes Don’t Get Slab Leaks”
The Myth: Solid construction prevents foundation leaks.
The Truth: Soil movement causes slab leaks—not exterior material.
Central Texas clay soil expands and contracts with moisture changes, stressing underground pipes regardless of home exterior.
13. “Low Water Pressure Means the City Has a Problem”
The Myth: It’s always the municipality’s fault.
The Truth: Internal plumbing issues are often to blame.
Clogged aerators, partially closed valves, hidden leaks, or mineral buildup are common causes inside the home.
14. “DIY Plumbing Saves Money”
The Myth: YouTube makes it easy.
The Truth: Improper repairs often cost more long-term.
Incorrect pipe connections, over-tightened fittings, or improper venting can lead to code violations and expensive damage.
15. “Plumbing Systems Don’t Need Maintenance”
The Myth: Install it and forget it.
The Truth: Plumbing systems require routine care—especially in Texas.
Hard water, high PSI, shifting soil, and heat stress all impact plumbing components. Preventive maintenance reduces emergency repairs and extends system lifespan.
