Plumbing is one of those things most homeowners don’t think about—until something goes wrong. But believing outdated or incorrect plumbing advice can lead to serious (and expensive) consequences. At Perry Plumbing & Pipelining, we’ve seen firsthand how common plumbing myths cost San Diego homeowners thousands in preventable damage.
Let’s bust the top 10 plumbing myths you should stop believing—before they bust your wallet.
1. A Leaky Faucet Is No Big Deal
That slow drip might not seem urgent, but it can waste hundreds of gallons of water per year. Over time, it not only drives up your water bill but can also lead to corrosion, mold, or water damage under sinks.
Truth: Fixing small leaks promptly can save water, money, and future repairs.
2. All Plumbers Are the Same
Hiring an unlicensed or inexperienced plumber might save you a few dollars upfront, but the cost of poor workmanship can be enormous.
Truth: Always choose a licensed, insured, and locally trusted plumber—especially for work involving gas lines, sewer systems, or major installations.
3. Flushable Wipes Are Safe to Flush
Despite the name, “flushable” wipes don’t break down like toilet paper. They often clog pipes, damage sewer systems, and contribute to major blockages.
Truth: Stick to toilet paper only. Toss wipes in the trash—even the ones labeled “flushable.”
4. It’s Okay to Use Chemical Drain Cleaners Regularly
Store-bought chemical cleaners may provide a quick fix, but over time they corrode pipes, especially in older San Diego homes with cast iron or galvanized plumbing.
Truth: Use mechanical methods (like plungers or drain snakes) or call a professional for persistent clogs.
5. Water Heaters Don’t Need Maintenance
Many homeowners ignore their water heaters until there’s a problem. But sediment buildup, corrosion, and worn-out components can reduce efficiency and lifespan.
Truth: Regular water heater maintenance—like flushing the tank annually—can extend its life and lower energy bills.
6. Low Water Pressure Is Just a Minor Nuisance
Low water pressure can indicate leaks, pipe corrosion, or slab foundation issues—common concerns in certain San Diego neighborhoods.
Truth: Ignoring low pressure can lead to serious plumbing failures. Get it checked early.
7. A Plunger Fixes Everything
Plungers are great for small clogs, but if you’re using one regularly, there’s likely a deeper issue in your pipes or sewer line.
Truth: Frequent clogs often require professional inspection and cleaning—possibly even trenchless sewer repair.
8. You Can Put Anything in a Garbage Disposal
Eggshells, coffee grounds, grease, pasta, and fibrous veggies like celery can all wreak havoc on your disposal and pipes.
Truth: Treat your disposal with care. When in doubt, throw it out.
9. If Water Drains, the Pipe Is Fine
Just because water drains slowly doesn’t mean the pipe is okay. Partial blockages or buildup inside the pipe can lead to sudden and total clogs.
Truth: Schedule preventative drain cleaning before small issues become plumbing emergencies.
10. DIY Plumbing Is Just as Good as Professional Work
YouTube can teach you a lot—but not everything. Incorrect installations or temporary fixes can lead to code violations, leaks, and property damage.
Truth: DIY has its place, but trust licensed professionals for anything involving water pressure, gas lines, or long-term plumbing health.
