What Does a Plumber Fix?

When water suddenly gushes out of a pipe like it’s auditioning for a fountain show, the first person you’ll probably call is a plumber.

But have you ever stopped to wonder what exactly plumbers fix? They’re not just the heroes of leaky faucets and clogged toilets—plumbers deal with an entire world of hidden systems under our feet and behind our walls.

1. Understanding What Plumbers Really Do

Plumbers are licensed tradespeople who install, repair, and maintain systems that involve water, gas, and drainage. According to the U.S. Bureau of Labor Statistics, there are over 469,000 plumbers, pipefitters, and steamfitters currently employed in the United States. That means there’s almost half a million people ensuring we can take hot showers, flush toilets, and cook with gas every single day.

Their work isn’t just limited to fixing leaks. A plumber’s tasks can include:

  • Installing new water supply lines in homes and commercial buildings.
  • Repairing gas pipes (yes, plumbers are trained for gas too).
  • Setting up water heaters and boilers.
  • Ensuring drainage systems are working correctly.
  • Handling emergency repairs like burst pipes or overflowing toilets.

Think of plumbers like the doctors of your home’s water and gas system—they diagnose, repair, and even perform preventative check-ups.

2. Common Household Fixes by Plumbers

Most people think of plumbers when something goes wrong inside their house. Here’s a breakdown of what plumbers commonly fix in homes:

  • Leaky faucets: One dripping faucet wastes about 3,000 gallons of water per year—which is basically 180 showers down the drain. A plumber can swap out washers, cartridges, or entire fixtures.
  • Clogged drains: From kitchen sinks stuffed with grease to showers clogged with hair, plumbers have the right tools (like augers and hydro-jetters) to clear blockages.
  • Running toilets: A running toilet can waste up to 200 gallons of water per day. Plumbers replace flappers, fill valves, or sometimes the entire toilet.
  • Burst pipes: Especially common in colder climates, frozen water expands and bursts pipes. Plumbers quickly replace sections and prevent future freezing with insulation.
  • Low water pressure: They track down the source, whether it’s corroded pipes, a faulty pressure regulator, or hidden leaks.
  • Water heater issues: No hot water? Plumbers repair heating elements, thermostats, or replace the tank itself.

Personal confession: I once tried to fix my own running toilet by “wiggling” the handle every time it didn’t stop. After two weeks of that nonsense, I called a plumber—he replaced a $12 part in under 10 minutes. Lesson learned: call the pro before you waste gallons (and your sanity).

3. Plumbing Repairs in Kitchens

The kitchen is the heart of most homes, but it’s also the battlefield of plumbing problems. Plumbers often deal with:

  • Garbage disposals: These tough grinders aren’t immortal. A plumber can unclog, reset, or replace them when they give up.
  • Dishwasher connections: Dishwashers need water lines and proper drainage—plumbers install and repair these connections to prevent leaks.
  • Sink leaks: From a worn-out P-trap to cracked pipes under the sink, plumbers track the source and replace parts fast.
  • Gas stoves: In many homes, plumbers install or repair gas lines that feed stoves, ensuring they’re safe and leak-free.

Here’s a stat that might surprise you: Over 14% of household water use is lost to leaks, according to the EPA. Kitchens are one of the top culprits.

4. Plumbing Fixes in Bathrooms

Bathrooms are where most people immediately think of plumbers. From toilets to tubs, this is their main domain. Here’s what they fix most often:

  • Showers and bathtubs: Clogged drains, dripping showerheads, and faulty faucets.
  • Toilets: Repairing clogs, leaks at the base, constant running, or full replacements.
  • Sinks: Fixing leaks, replacing faucets, unclogging drains.
  • Pipe replacements: Many bathroom issues come from old or corroded pipes that need updating.

Bathrooms also see more water damage than any other room. A slow leak behind the wall can rot drywall, floors, and even ceilings below. Plumbers use specialized tools like moisture meters and inspection cameras to detect problems early.

5. Emergency Plumbing Fixes

Let’s be real: you rarely call a plumber for fun—it’s usually an emergency. Here are situations where plumbers swoop in like superheroes:

  • Burst pipes flooding a room
  • Overflowing toilets right before guests arrive (always seems to happen on holidays, doesn’t it?)
  • Gas leaks that can’t be ignored—plumbers are trained to shut down and repair these safely.
  • No hot water in winter—a broken water heater is more than inconvenient in freezing weather.

According to HomeAdvisor, the average emergency plumbing repair costs anywhere from $150 to $600, depending on the severity. It’s painful for the wallet, but a small price compared to ignoring it and dealing with water damage worth thousands.

6. What Plumbers Fix Outdoors

Plumbing isn’t just indoors—it stretches outside too. Plumbers are often called for:

  • Outdoor spigots: Broken hose bibs leak like crazy and waste gallons.
  • Sewer line blockages: Tree roots are notorious for cracking and blocking sewer pipes underground.
  • Sprinkler systems: Many plumbers install and repair irrigation systems.
  • Gas lines for grills: Want an outdoor kitchen? A plumber runs the gas safely.

Fun fact: Tree roots cause 50% of sewer blockages in older homes. Plumbers use camera inspections and trenchless repair techniques to handle this without tearing up your entire yard.

7. Gas Line Repairs and Installations

Not everyone knows this, but plumbers also work with natural gas systems. They fix:

  • Gas leaks (urgent and dangerous).
  • Gas water heaters.
  • Gas stoves and ovens.
  • Outdoor fire pits and grills.

Gas line work is highly regulated, and you definitely don’t want to DIY this one. A small leak could lead to explosions or carbon monoxide poisoning. This is one of those “don’t even try it” fixes—leave it to a licensed plumber.

8. Water Heater Repairs and Installations

Hot showers are something we take for granted until suddenly the water runs icy. Plumbers fix:

  • Pilot light problems.
  • Thermostat issues.
  • Heating element replacements.
  • Full water heater installations (tank and tankless).

Did you know? Water heaters make up about 18% of your home’s energy bill, according to the U.S. Department of Energy. Keeping them in top shape isn’t just convenient—it’s money-saving.

9. Sewer and Drain Repairs

Sewer issues are the nightmare scenario. Plumbers are equipped to handle:

  • Blocked sewer lines.
  • Broken sewer pipes.
  • Sewage backups into the home.
  • Hydro-jetting to clear major clogs.

When your house smells like rotten eggs and drains are gurgling, it’s time to call a plumber immediately. Ignoring sewer issues can lead to health hazards, property damage, and major repair costs.

10. Preventative Plumbing Maintenance

The smartest homeowners don’t wait for disasters—they call plumbers for preventative check-ups. Maintenance includes:

  • Annual water heater flushes to remove sediment.
  • Checking for small leaks before they become big.
  • Inspecting sump pumps (critical in flood-prone areas).
  • Testing water pressure regulators.
  • Sewer line camera inspections every few years.

According to insurance companies, water damage claims are the second most common type of home insurance claim, averaging $11,650 per incident. Preventative plumbing saves thousands by catching problems early.

11. The Tools Plumbers Use

Part of what makes plumbers so effective is their arsenal of specialized tools. A few examples:

  • Pipe wrenches for gripping and turning.
  • Augers and snakes for clearing drains.
  • Hydro-jetters that blast high-pressure water to clear blockages.
  • Cameras for inspecting inside pipes.
  • Pipe cutters for precision replacements.
  • Leak detection devices for hidden issues.

It’s like Batman’s utility belt—only instead of fighting crime, they’re fighting leaks and clogs.

12. When You Should Call a Plumber vs DIY

Let’s be honest—many of us try to fix things ourselves first. But here’s the rule of thumb:

  • DIY okay: Changing showerheads, tightening a loose faucet handle, unclogging a minor drain with a plunger.
  • Call a plumber: Gas issues, major leaks, sewer backups, water heater repairs, burst pipes.

A study by Porch.com found that 65% of DIY plumbing attempts end up requiring professional help anyway. Translation? You might save money by calling the plumber first instead of after making it worse.

13. How Much Do Plumbers Charge?

Plumbing isn’t cheap, but it’s necessary. Typical pricing:

  • Hourly rates: $45–$200 depending on region and experience.
  • Flat fees for simple jobs like faucet replacement: $100–$300.
  • Emergency calls: Often 1.5–2x normal rates.

Remember, you’re not just paying for time—you’re paying for years of training, licensing, and the peace of mind that your home won’t turn into an indoor swimming pool.

14. Commercial Plumbing Fixes

Plumbers don’t just work on homes—they also handle commercial plumbing systems. This includes:

  • Large water heaters and boilers.
  • Complex drain systems for restaurants.
  • Gas piping for industrial kitchens.
  • Sewer maintenance for apartment complexes.

Commercial jobs are often more intense because they involve high-capacity systems that serve dozens or hundreds of people.

15. The Future of Plumbing: Smart Homes and Eco-Friendly Fixes

Plumbing isn’t stuck in the past—it’s adapting to modern life. Plumbers are now installing:

  • Smart leak detectors that send alerts to your phone.
  • Tankless water heaters for efficiency.
  • Greywater systems that recycle water for irrigation.
  • Touchless faucets and toilets for hygiene.

Sustainability matters too. The EPA estimates that if every household fixed leaks, it could save 1 trillion gallons of water per year nationwide. Plumbers play a huge role in that conservation.

16. Why Plumbers Are Essential

Without plumbers, our homes would literally fall apart. No hot showers, no flushing toilets, no clean drinking water, no safe gas lines. They’re the unsung heroes of daily life, and the problems they fix are often invisible until disaster strikes.

Conclusion

So, what does a plumber fix? The short answer: almost everything that involves water, gas, or drains in your home and beyond. From leaky faucets to life-threatening gas leaks, plumbers handle it all. They’re not just fixers—they’re preventers, installers, and life-savers for your property.

If you ever find yourself staring at a puddle forming where it shouldn’t, don’t panic—just remember that a plumber’s expertise is only a call away.
