5 Things You’re Doing That Are Ruining Your Pipes

Think your pipes are safe because you don’t see any leaks? Think again. Many common household habits quietly damage your plumbing over time, leading to costly repairs or major emergencies.

According to the EPA, household leaks can waste nearly 1 trillion gallons of water annually nationwide. Often, those leaks start as minor damage caused by routine behaviors—until they spiral into something worse.

If you're dealing with recurring issues, it might be time to break some bad habits—or call a plumber in San Dimas residents trust for professional help. Here are five things you may be doing that are quietly ruining your plumbing.

1. Pouring Grease Down the Drain

It might feel convenient to pour used cooking oil or grease down your sink while it’s still hot, but that decision can lead to major trouble. Once the grease cools, it hardens and sticks to the inside of your pipes, trapping food scraps and debris.

This creates thick, sticky blockages that grow over time, eventually leading to full clogs, slow drainage, or even a sewage backup.

What to do instead:

• Let grease cool, then scrape it into the trash.

• Wipe greasy cookware with paper towels before rinsing.

• Use a mesh drain strainer to catch food particles.

Even a few tablespoons of oil a week can lead to plumbing problems if you keep the habit up.

2. Overusing Chemical Drain Cleaners

Those brightly colored drain cleaners might seem like a quick fix, but they’re often loaded with corrosive chemicals like lye and hydrochloric acid. These ingredients can wear down your pipes just as fast as they dissolve clogs.

With repeated use, chemical drain cleaners weaken pipe walls—especially in older metal pipes—making them more likely to crack or burst under pressure.

Better alternatives:

• Try a manual drain snake or auger to remove blockages.

• Use enzyme-based cleaners that break down organic material without damaging pipes.

• When in doubt, call a plumber in San Dimas homeowners trust to safely and thoroughly clear clogs without harming your plumbing.

These alternatives may take a little more time, but they’re far safer for your pipes in the long run.

3. Flushing Non-Flushable Items

Toilets are only meant to handle human waste and toilet paper. But too often, people treat them like garbage disposals—flushing wipes, tissues, paper towels, and other “flushable” items that really aren’t.

Even products labeled as "flushable" often fail to break down quickly, creating clumps that clog your pipes or damage your sewer system.

Common offenders include:

• Baby wipes and makeup wipes

• Cotton balls and Q-tips

• Feminine hygiene products

• Dental floss and hair

• Cat litter—even the “flushable” kind

How to prevent problems:

• Educate family members and house guests on what should never go down the toilet.

• Keep a small trash can in each bathroom for proper disposal.

• Consider a bidet as a safer, sanitary alternative to wipes.

Clogs from non-flushables often happen deep in the plumbing, where they’re harder (and more expensive) to reach and repair.

4. Ignoring Small Leaks

A steady drip from your faucet might seem like a minor nuisance, but it could be the tip of a much larger problem. Even small leaks waste water, erode pipe joints, and raise your water bills.

Worse, leaks behind walls or under sinks can lead to hidden water damage, encouraging mold growth and rotting wood or drywall.

Signs you might have a hidden leak:

• Musty smells or soft spots on floors and walls

• Unexplained increases in your water bill

• Mold, mildew, or bubbling paint on walls

• The sound of water running even when no fixtures are on

Fixing small leaks quickly helps you avoid big repairs later. If you suspect a hidden leak, don’t wait—contact a professional for leak detection and repair.

5. Letting Your Water Pressure Stay Too High

While a strong shower feels great, high water pressure can wreak havoc on your plumbing system over time. Pipes, fixtures, and water heaters are all designed to handle a certain range—typically between 40 and 60 psi.

Anything higher than 80 psi can stress your pipes, loosen joints, and wear out appliances prematurely. Homes without a pressure regulator are especially vulnerable.

How to handle it:

• Use a pressure gauge (available at hardware stores) to test your system.

• Install a pressure-reducing valve if your pressure is consistently high.

• Schedule annual plumbing maintenance to check for high-pressure-related damage.

Consistently high pressure may feel like a luxury, but it shortens the life of your plumbing and increases the risk of pipe bursts.

Frequently Asked Questions

Q: Can I pour hot water down the drain to break up grease?
A: Hot water may temporarily move grease along the pipe, but once it cools, the grease still hardens. This only pushes the problem further down the line. Instead, dispose of grease in the trash and clean drains regularly with baking soda and vinegar.

Q: Are enzyme cleaners really safe for pipes?
A: Yes. Enzyme-based cleaners use natural bacteria to digest organic waste without damaging pipe walls. They're especially useful for homes on septic systems or with older plumbing.

Q: How can I tell if my water pressure is too high?
A: Attach a pressure gauge to an outdoor hose spigot. If the reading exceeds 80 psi, your pressure is too high and may need to be reduced with a regulator.

Q: What should I do if I accidentally flushed a wipe or non-flushable item?
A: If it happens once, there may be no issue—but watch for signs of slow drains. If you notice recurring problems, contact a plumber to inspect and clear any developing clogs.

Q: How often should I inspect for leaks?
A: You should visually inspect your faucets, under-sink pipes, and exposed plumbing monthly. A professional inspection every 1–2 years can catch hidden leaks early.
