Most homeowners don’t intentionally damage their plumbing system.
In fact, nearly every major plumbing problem we see starts with something that seemed completely harmless at the time.
Pouring a little grease down the kitchen sink.
Using a chemical drain cleaner.
Ignoring a small drip under the bathroom sink.
Waiting one more month to fix a running toilet.
These everyday habits slowly put stress on your home’s plumbing system until one day a drain backs up, a pipe leaks, a water heater fails, or an expensive emergency repair becomes unavoidable.
At Ascend Plumbing, we’ve helped homeowners throughout San Diego, La Jolla, Chula Vista, Poway, Mission Valley, Rancho Bernardo, Point Loma, and communities across San Diego County solve thousands of plumbing problems. Many of them could have been prevented with a few simple changes.
Here are ten of the most common plumbing mistakes—and what you should do instead.
- Pouring Grease Down the Kitchen Sink
It may be liquid when it’s hot, but grease quickly cools inside your drain pipes.
Over time it hardens, trapping food particles and creating stubborn blockages that eventually restrict water flow.
Many homeowners don’t connect today’s dinner cleanup with next month’s clogged kitchen sink—but the two are often related.
Better Solution
Allow grease to cool, pour it into a disposable container, and throw it in the trash.
Your kitchen drain—and your sewer line—will thank you.
- Treating Your Garbage Disposal Like a Trash Can
Garbage disposals are convenient, but they’re not designed to grind everything.
Avoid putting these items down the disposal:
- Grease and cooking oils
- Coffee grounds
- Eggshells
- Celery
- Corn husks
- Onion skins
- Pasta
- Rice
- Potato peels
- Bones
Many of these materials either expand, wrap around moving parts, or contribute to drain blockages farther down the plumbing system.
- Flushing “Flushable” Wipes
Despite the label, many products marketed as “flushable” do not break down like toilet paper.
They frequently contribute to:
- Toilet clogs
- Sewer line blockages
- Pump failures
- Expensive sewer repairs
Only toilet paper and human waste should ever be flushed.
- Ignoring Small Leaks
A faucet that drips once every few seconds may seem like a minor annoyance.
But small leaks often become larger leaks.
They also waste water, increase utility bills, and can damage cabinets, flooring, drywall, and insulation over time.
If you notice a leak, it’s almost always less expensive to repair it early.
- Using Chemical Drain Cleaners Repeatedly
Store-bought drain cleaners promise a quick fix.
Unfortunately, they often provide only temporary relief.
Repeated use can:
- Damage older pipes
- Harm plumbing fixtures
- Fail to remove the actual blockage
- Make future repairs more difficult
Professional drain cleaning removes the problem rather than simply burning through part of it.
- Forgetting About Your Water Heater
Your water heater works every day of the year, yet many homeowners never think about it until they have no hot water.
Routine maintenance—including periodic flushing and inspections—can help:
- Improve efficiency
- Extend equipment life
- Reduce sediment buildup
- Identify problems before leaks develop
A little maintenance today may help postpone a costly replacement tomorrow.
- Ignoring Slow Drains
A slow drain is often your plumbing system asking for help.
Hair, soap, grease, mineral deposits, and debris gradually build inside drain pipes.
Many homeowners wait until the drain stops completely.
By then, what could have been a simple drain cleaning may require a much larger repair.
- Not Knowing Where the Main Water Shutoff Valve Is
Every homeowner should know this before an emergency happens.
When a pipe bursts, every minute matters.
Knowing how to quickly shut off your home’s water can dramatically reduce water damage while you’re waiting for a plumber to arrive.
If you aren’t sure where your shutoff valve is located, ask your plumber during your next service visit.
- Skipping Routine Plumbing Inspections
Most homeowners schedule maintenance for their vehicles—but never for their plumbing.
A professional plumbing inspection can identify:
- Hidden leaks
- Water pressure problems
- Aging fixtures
- Drain issues
- Water heater concerns
- Sewer line problems
Finding these issues early often prevents emergency repairs later.
- Hiring Based Only on Price
We understand the temptation.
Everyone wants to save money.
But the lowest estimate isn’t always the least expensive repair.
Quality workmanship, proper diagnosis, professional equipment, and honest recommendations often save homeowners significantly more over the life of the plumbing system than choosing the lowest initial bid.
The right repair done once is almost always less expensive than the wrong repair done twice.
The Good News
Here’s the encouraging part.
Nearly every plumbing mistake on this list is preventable.
You don’t need to become a plumbing expert.
Just paying attention to the warning signs—and addressing small issues before they become emergencies—can dramatically reduce the likelihood of expensive repairs.
Common Questions Homeowners Ask
Can a slow drain really become a sewer backup?
Yes.
Many sewer problems begin with recurring slow drains that gradually worsen over time.
Are chemical drain cleaners ever okay?
Occasional use may not immediately damage every plumbing system, but repeated use is generally not the best long-term solution for recurring drain problems.
How often should my plumbing be inspected?
Most homeowners benefit from a professional plumbing inspection every one to two years, especially in older homes.
What’s the most common plumbing mistake?
Ignoring small leaks is one of the biggest—and most expensive—mistakes we see.
