The Most Common Plumbing Mistakes Homeowners Make (and How to Avoid Them)

Every homeowner wants to save money and keep their plumbing system running smoothly. While some plumbing tasks are simple enough to tackle yourself, certain mistakes can lead to expensive repairs, water damage, and unnecessary frustration. Here are some of the most common plumbing mistakes homeowners make—and how to avoid them.

1. Using Chemical Drain Cleaners

When a drain slows down, many people reach for a chemical drain cleaner. While these products may provide a temporary fix, they can also damage your pipes over time, especially in older plumbing systems.

Instead: Try a plunger or drain snake, or call a professional if the clog persists.

2. Ignoring Small Leaks

A dripping faucet or a small leak under the sink may not seem urgent, but even minor leaks can waste thousands of gallons of water each year and cause hidden water damage.

Instead: Repair leaks as soon as you notice them to prevent bigger problems.

3. Flushing the Wrong Items

Toilets are designed to handle only human waste and toilet paper. Items labeled "flushable," along with paper towels, wipes, feminine hygiene products, and cotton swabs, can clog your plumbing and sewer lines.

Instead: Throw these items in the trash, not the toilet.

4. Pouring Grease Down the Drain

Hot grease may go down the drain as a liquid, but it hardens as it cools, creating stubborn blockages inside your pipes.

Instead: Allow grease to cool, then dispose of it in the trash.

5. Overloading the Garbage Disposal

Garbage disposals are not designed to grind everything. Fibrous vegetables, coffee grounds, eggshells, bones, and grease can damage the unit or clog your drains.

Instead: Compost or throw these items away and use plenty of cold water when running the disposal.

6. Forgetting About the Water Heater

Many homeowners never think about their water heater until it stops working. Without routine maintenance, sediment buildup can reduce efficiency and shorten its lifespan.

Instead: Have your water heater inspected and flushed according to the manufacturer's recommendations.

7. Not Knowing Where the Main Water Shut-Off Valve Is

If a pipe bursts, every second counts. Not knowing how to shut off your home's water can result in significant water damage.

Instead: Locate your main water shut-off valve and make sure everyone in your household knows where it is.

8. Overtightening Plumbing Connections

It's easy to think tighter is better, but overtightening supply lines, fittings, or plumbing fixtures can crack components and cause leaks.

Instead: Tighten connections only as much as needed to create a proper seal.

9. Ignoring High Water Pressure

High water pressure may feel great in the shower, but it can strain pipes, fixtures, water heaters, and appliances.

Instead: If your water pressure consistently exceeds 80 PSI, have it tested and consider installing a pressure-reducing valve.

10. Waiting Too Long to Call a Plumber

Small plumbing problems rarely fix themselves. Delaying repairs often turns an inexpensive service call into a costly emergency.

Instead: If you notice leaks, unusual noises, slow drains, or changes in water pressure, have them inspected before they become major repairs.

Why Is My Drain Clogged?

A slow or clogged drain is one of the most common plumbing problems homeowners face. Whether it's your kitchen sink, bathroom sink, shower, or tub, a clog can quickly go from a minor annoyance to a major headache.

Here are some of the most common reasons your drain may be clogged—and what you can do about it.

Bathroom Drains: Hair Is Usually the Culprit

Hair is the number one cause of clogged bathroom drains. Over time, hair combines with soap scum, toothpaste, and other debris to form a stubborn blockage that slows or completely stops water from draining.

Signs of a hair clog include:

• Water draining slowly.

• Standing water in the shower or sink.

• Gurgling sounds.

• Unpleasant odors coming from the drain.

What you can do:

• Remove visible hair from the drain.

• Try using a drain snake or zip tool.

• Avoid chemical drain cleaners, as they can damage your pipes over time.

Kitchen Drains: Grease Is the Biggest Offender

Many people think it's okay to pour hot grease down the drain because it's liquid. Unfortunately, once that grease cools, it hardens inside your pipes and traps food particles, creating a stubborn clog.

Other common causes include:

• Coffee grounds

• Rice and pasta

• Eggshells

• Fibrous vegetables like celery

• Food scraps that should have gone in the trash

Prevention tips:

• Pour cooking grease into a disposable container instead of the sink.

• Use a sink strainer to catch food particles.

• Run plenty of cold water when using your garbage disposal.

Toilets Can Clog Too

A toilet is designed to handle only human waste and toilet paper. Flushing anything else can lead to a blockage.

Common offenders include:

• "Flushable" wipes

• Paper towels

• Feminine hygiene products

• Cotton swabs

• Excessive amounts of toilet paper

If your toilet clogs frequently, there could be a larger issue deeper in the drain line.

Tree Roots Can Invade Sewer Lines

If multiple drains in your home are backing up at the same time, the problem may not be inside your house at all.

Tree roots naturally seek moisture and can enter tiny cracks in underground sewer pipes. Once inside, they continue growing until they partially or completely block the line.

Warning signs include:

• Several drains backing up at once.

• Toilets bubbling when another fixture is used.

• Sewage odors.

• Water backing up into tubs or showers.

This type of clog usually requires professional equipment such as a sewer camera inspection and hydro jetting.

Can I Use Chemical Drain Cleaners?

While they're heavily advertised, chemical drain cleaners often do more harm than good.

They can:

• Damage older pipes.

• Harm plumbing fixtures.

• Create safety hazards for anyone working on the drain later.

• Fail to remove the actual blockage.

A mechanical drain cleaning is typically safer and more effective.

How to Help Prevent Drain Clogs

A few simple habits can save you from costly plumbing repairs:

• Keep hair out of bathroom drains with drain screens.

• Never pour grease or oil down the sink.

• Scrape food into the trash before washing dishes.

• Only flush toilet paper and human waste.

• Have your drains professionally cleaned if they begin slowing down.

If you've tried basic methods and your drain is still slow—or if multiple drains are clogged—it may be time for professional help. A plumber can identify the true cause of the blockage and clear it without damaging your plumbing system.
