Plumbing problems can be frustrating, whether a dripping tap, a blocked drain, or an unexpected cold shower. Some issues can be fixed with simple DIY solutions, while others require the expertise of a professional plumber.
If you’re experiencing ongoing plumbing issues, our professional plumbers in Eastern Suburbs can help diagnose and repair problems before they become costly. But for minor concerns, here’s a guide to the 10 most common plumbing problems and how you can fix them.
1. Dripping taps
A dripping tap might not seem like a big deal, but over time, it can waste litres of water and increase your bill. Usually, a worn-out washer or cartridge is the culprit.
Fix:
- Turn off the water supply.
- Disassemble the tap and replace the washer or cartridge.
- Reassemble and test for leaks.
If the problem continues, the valve seat might need attention.
2. Blocked drains
Slow-draining water in the sink or shower? It’s likely a buildup of hair, grease, food scraps, or soap scum.
Fix:
- Use a plunger to loosen the blockage.
- Avoid harsh chemical cleaners—they can damage pipes and are bad for the environment.
- For ongoing issues, professional drain cleaning is a smart solution. A professional plumber can use a drain machine if needed to clear the blockage effectively.
3. Running toilet
A toilet that won’t stop running can waste hundreds of litres of water a day! The usual suspect? A worn-out or a faulty fill valve.
Fix:
- Turn off the water supply to the toilet.
- Check the flapper and replace it if worn.
- Adjust or replace the fill valve if needed.
If the problem doesn’t go away, there could be a bigger issue inside the cistern.
4. Low water pressure
Weak water pressure can turn a refreshing shower into a frustrating trickle. It’s often caused by clogged aerators, leaks, or old pipes.
Fix:
- Clean the aerator in your tap or showerhead.
- Check for leaks under sinks or around pipes.
- If the whole house has low pressure, contact a plumber to investigate.
5. Leaking pipes
Even a small leak can lead to water damage and mould growth. Pipes can leak due to age, corrosion, or loose connections.
Fix:
- Shut off the water supply.
- Use pipe tape, epoxy putty, or a clamp as a temporary fix.
- For major leaks, the damaged section of the pipe will need replacing by a professional plumber.
6. Burst pipes
A burst pipe is an emergency—whether from ageing pipes, high water pressure, or physical damage, it can cause serious water damage.
Fix:
- Turn off the main water supply immediately.
- Drain the system by opening the taps.
- Call a plumber to repair or replace the pipe.
Prevent future bursts by insulating pipes and monitoring water pressure.
7. Water heater problems
No hot water? Your water heater might have a faulty thermostat, heating element, or sediment buildup inside the tank.
Fix:
- Check the power supply and thermostat settings.
- Check if the pilot light is on.
- Flush the system to remove sediment.
- Replace the heating element if needed.
If your unit is old or leaking, it may be time for a replacement.
8. Sewer line blockages
A blocked sewer line can cause slow drains, foul odours, and even sewage backups in your home. Common culprits are tree roots, grease buildup, or foreign objects flushed down the toilet.
Fix:
- Avoid flushing anything other than toilet paper and waste.
- A plumber may need to clear the line using a drain machine to cut & remove the roots.
- If tree roots are the issue, regular maintenance is essential to prevent recurring blockages. In some cases, if a drain machine is unsuccessful in clearing the blockage, excavation may be necessary to replace the faulty section of the drain.
9. Blocked stormwater drains
Heavy rain can overwhelm your stormwater drains, leading to water pooling around your home, flooding, and potential property damage.
The common causes of blocked stormwater drains are leaves, dirt, debris, or tree roots obstructing the pipes.
Fix:
- Remove visible debris from grates and gutters.
- If water still isn’t draining properly, it’s probably time to call a blocked drains plumber to clear stubborn obstructions with a drain machine.
- Regular gutter and drain maintenance can help prevent future blockages.

10. Smelly drains
Foul odours from your drains are often caused by bacteria, trapped food waste, or dry P-traps. A foul smell could also indicate a deeper sewer issue.
Fix:
- Pour a mixture of hot water and baking soda down the drain.
- Check that the P-trap under the sink has water—this acts as a barrier against sewer gases.
- For persistent odours, a professional drain cleaning may be necessary.
