Top 5 Plumbing Repairs Every Homeowner Should Know

Every homeowner eventually faces issues that require plumbing repairs. From dripping faucets to clogged drains, knowing how to handle some basic fixes yourself can save you both time and money. While not every plumbing problem is a DIY job, understanding the most common ones empowers you to decide when to take action and when to call in a pro. Let’s explore the top five plumbing repairs that every homeowner should be familiar with.

1. Fixing a Leaky Faucet

A dripping faucet isn’t just annoying—it can waste hundreds of gallons of water per year. The culprit is usually a worn-out washer or O-ring inside the faucet mechanism. In most cases, you can disassemble the faucet using a wrench, identify the faulty component, and replace it with a matching part from your local hardware store.

For this repair:

Turn off the water supply under the sink.

Plug the drain to avoid losing small parts.

Use the proper tools to avoid damaging the fixture.

This type of plumbing repair is among the easiest, and doing it yourself often costs under $10.

2. Unclogging Drains

Whether it’s the kitchen sink, bathroom basin, or shower, clogged drains are a common nuisance. Grease, hair, and soap residue tend to accumulate over time, restricting water flow. While chemical drain cleaners are widely available, they can damage pipes if used repeatedly. A better option is to use a plunger or a drain snake.

For minor clogs:

Try pouring boiling water down the drain.

Use a mixture of baking soda and vinegar to dissolve buildup.

If that fails, use a hand auger (drain snake) to remove deeper blockages.

Keeping your drains clean through regular maintenance can prevent major plumbing issues later on.

3. Replacing a Toilet Flapper

If your toilet keeps running after you flush, it could be a faulty flapper in the tank. The flapper is a rubber valve that controls water flow from the tank to the bowl. When it doesn’t seal properly, water continuously leaks, causing your toilet to run and your water bill to rise.

To fix this:

Turn off the toilet’s water supply.

Drain the tank by flushing.

Remove the old flapper and install a new one, making sure it fits snugly over the valve seat.

This simple plumbing repair usually takes less than 15 minutes and requires no special tools.

4. Fixing Low Water Pressure

Low water pressure can make everyday tasks like showering or washing dishes frustrating. It may be due to mineral buildup in faucet aerators or showerheads. In some cases, it could be a sign of a bigger problem, like a pipe leak or an issue with your main water line.

Start with the easy fixes:

Unscrew the aerator or showerhead and soak it in vinegar to dissolve mineral deposits.

Rinse thoroughly and reinstall.

If pressure is still low throughout the house, it’s wise to contact a licensed plumbing professional to inspect for more serious issues.

5. Repairing a Running Toilet Fill Valve

If your toilet won’t fill correctly or makes a hissing sound, the fill valve may be at fault. This component regulates the tank’s water level after flushing. Over time, it can wear out or become misaligned, leading to inefficient flushing or constant refilling.

To replace a faulty fill valve:

Shut off the water and empty the tank.

Disconnect the water supply line and remove the old valve.

Install a new one, adjusting the float to set the correct water level.

Most fill valve kits come with instructions and are designed for easy installation, even for beginners.

Why Basic Plumbing Skills Matter

Being familiar with these fundamental plumbing repairs can help you respond quickly during emergencies and reduce reliance on professionals for minor issues. That said, some situations—like burst pipes, sewage backups, or problems inside walls—require professional expertise and specialized equipment.

Taking preventive steps, such as insulating exposed pipes and regularly inspecting visible plumbing, can also extend the life of your system and reduce the frequency of repairs.

When to Call a Professional

While many homeowners are capable of handling small repairs, knowing your limits is just as important. If you’re unsure about the scope of a problem, it’s better to consult a licensed plumber. Incorrect repairs can lead to water damage, mold growth, and expensive remediation costs.

Every homeowner should feel empowered to take on basic plumbing repairs, from fixing a leaky faucet to replacing a toilet flapper. These small tasks, when done right, can maintain your home’s comfort and reduce your utility bills. A little knowledge, the right tools, and some confidence can go a long way in keeping your plumbing in great shape.

Remember, plumbing doesn’t have to be intimidating. With practice and precaution, you can handle many common issues yourself—and for everything else, a trusted plumber is just a call away.
