10 Common Plumbing Problems and How to Fix Them

Plumbing issues are something every homeowner faces at some point. From dripping taps to blocked drains, these problems can disrupt your daily routine and even cause long-term damage if left unattended. The good news? Many common plumbing problems can be fixed easily with a little knowledge and the right approach. In this blog, we’ll discuss 10 of the most common plumbing problems and simple tips on how you can fix them — or when it’s time to call in the professionals.

1. Dripping Taps

A dripping tap might seem harmless, but over time it can waste litres of water and increase your water bill. This usually happens when the washer or O-ring inside the tap wears out. Fix it: Turn off the water supply, disassemble the tap handle, and replace the washer with a new one of the same size. If the problem persists, the valve seat might be corroded — in which case, it’s best to call a plumber.

2. Leaking Pipes

Leaking pipes can lead to damp walls, mould, and even structural damage. Most leaks occur at joints or from cracked pipes due to pressure or age. Fix it: For a temporary solution, use pipe sealant tape or a rubber patch with a hose clamp. However, leaks often indicate a deeper issue, so it’s important to get them checked by a professional plumber for a long-term fix.

3. Running Toilets

A running toilet wastes a surprising amount of water — sometimes up to 200 gallons a day! This problem is often caused by a faulty flapper valve or an issue with the float. Fix it: Remove the toilet tank lid and inspect the flapper valve. If it looks worn or doesn’t seal properly, replace it. You can also adjust the float arm if the water level is too high. Toilet repair kits are inexpensive and easy to install.

4. Low Water Pressure

If water trickles instead of flowing smoothly, you’re likely facing a low water pressure issue. This can result from mineral buildup in pipes or a hidden leak. Fix it: Start by cleaning the aerator on your tap or showerhead — mineral deposits often collect there. If that doesn’t help, check for leaks or corroded pipes. Consistent low pressure across your home might require professional inspection of your main water line.

5. Blocked Drains

Slow-draining sinks or showers are usually signs of a blockage caused by soap, hair, grease, or food particles. Fix it: Pour boiling water down the drain followed by a mixture of baking soda and vinegar. Let it sit for 15 minutes, then flush again with hot water. Avoid using harsh chemical drain cleaners as they can damage pipes. For severe clogs, a plumber can use professional drain cleaning equipment to clear the line.

6. Leaking or Faulty Water Heater

If your hot water suddenly turns cold, your water heater might be at fault. Common causes include sediment buildup, faulty thermostats, or leaks in the tank. Fix it: Check if the pilot light is on and inspect for any visible leaks. If you notice water pooling around the base or hear unusual noises, turn off the power supply and call a licensed plumber — water heater repairs should never be attempted without proper expertise.

7. Jammed Garbage Disposal

A jammed garbage disposal can make your kitchen sink unusable and create unpleasant smells. Fix it: First, never put your hand inside the disposal unit. Turn off the power, use an Allen key to manually rotate the blades from underneath, and remove any visible blockages with tongs or pliers. Avoid putting fibrous foods, coffee grounds, or grease down the disposal to prevent future jams.

8. Clogged Toilet

A clogged toilet is one of the most common household emergencies. It’s usually caused by excessive toilet paper or non-flushable items. Fix it: Use a plunger to create suction and clear the blockage. If that doesn’t work, a plumbing snake or auger can help dislodge tougher clogs. Recurrent blockages might indicate a deeper drainage issue that needs professional inspection.

9. Noisy Pipes (Water Hammer)

If you hear banging or knocking noises when turning off taps, you might be experiencing “water hammer.” This happens when water flow stops suddenly, creating pressure shocks inside the pipes. Fix it: Secure any loose pipes with clamps and install a water hammer arrestor to absorb the shock. Persistent noise may indicate high water pressure or air in the system, which a plumber can easily diagnose.

10. Sewer System Backup

A sewer backup is one of the most unpleasant plumbing issues, often accompanied by foul odours and slow drains throughout the house. It’s usually caused by tree root intrusion or a blockage in the main sewer line. Fix it: If multiple drains are backing up simultaneously, don’t use any plumbing fixtures. Call a professional immediately to inspect and clear the main line. Regular drain cleaning and tree root management can prevent this costly problem.

Final Thoughts

Plumbing problems are inevitable, but most can be prevented with regular maintenance and quick action when issues arise. While DIY fixes can handle minor problems, it’s important to know your limits — complex issues like leaks behind walls, sewer backups, or faulty heaters should always be handled by qualified professionals.

Keeping your plumbing system in top shape not only ensures comfort and convenience but also protects your property from costly damage. So the next time you notice a dripping tap or slow drain, take action early — your home (and your wallet) will thank you!
