Plumbing issues are a common household headache, and they always seem to happen at the worst times. Whether it’s a leaking tap keeping you up at night or a clogged drain slowing down your day, knowing how to handle these problems can save you time, money, and stress.
Some plumbing issues can be resolved with simple DIY methods, but others require professional attention to prevent bigger damage. Below, we’ll go through 10 of the most common plumbing problems, how you can attempt to fix them, and when it’s best to call a plumber.
1. Dripping Taps
A dripping tap may not seem like a big issue, but it can waste hundreds of litres of water per year, leading to a higher water bill. It’s often caused by a worn-out washer, O-ring, or a faulty valve seat.
How to Fix It:
- Turn off the water supply to the tap.
- Remove the tap handle and unscrew the packing nut.
- Replace the washer or O-ring inside the tap.
- Reassemble the tap and turn the water back on.
If replacing the washer doesn’t stop the drip, the issue could be a corroded valve seat—this requires professional repair or tap replacement.
2. Clogged Drains
A slow or blocked drain is a frustrating and messy problem. Hair, grease, soap scum, food particles, and other debris can build up over time, restricting water flow.
How to Fix It:
- Use a plunger to create suction and dislodge minor blockages.
- Pour boiling water mixed with baking soda down the drain.
- Try a drain snake or auger to remove deeper clogs.
If water still isn’t draining properly, the blockage may be deeper in the pipes, requiring professional drain cleaning.
3. Low Water Pressure
Weak water flow from taps or showers can make daily tasks like washing dishes or showering frustrating. This could be due to mineral buildup, pipe leaks, or faulty pressure regulators.
How to Fix It:
- Check if all fixtures have low pressure—if yes, it may be a problem with the main water supply.
- Remove and clean the aerator on taps and showerheads to remove buildup.
- Inspect visible pipes for leaks that could be affecting water flow.
If pressure is still low, the issue may be with hidden leaks or a pressure regulator, which needs a plumber’s expertise.
4. Running Toilet
A constantly running toilet can waste litres of water per day. It’s often caused by a faulty flapper valve, a misaligned float, or a broken fill tube.
How to Fix It:
- Open the tank and check the flapper valve—if it’s worn out, replace it.
- Adjust the float height to stop excess water from filling the tank.
- Ensure the refill tube is properly positioned to prevent overflow.
If these fixes don’t work, you may need professional toilet repair.
5. Water Leaks
Leaks can occur in pipes, taps, water heaters, and even toilets, leading to water damage, mould growth, and increased water bills.
How to Fix It:
- Identify the source of the leak.
- Use a wrench to tighten loose fittings.
- Apply plumber’s tape for small leaks.
For hidden leaks behind walls or under floors, professional leak detection and repair is essential.
6. No Hot Water
A sudden loss of hot water can indicate issues with your hot water system, thermostat, or heating element.
How to Fix It:
- Check if the thermostat settings are too low.
- If you have a gas water heater, check if the pilot light is out.
- For electric systems, reset the circuit breaker.
If none of these solve the problem, your hot water system may need repairs or replacement.
7. Gurgling Drains
If you hear gurgling sounds coming from your drains, it’s a sign of blockages or ventilation issues in your plumbing system.
How to Fix It:
- Use a plunger to dislodge minor clogs.
- Inspect vent pipes for blockages.
If gurgling continues, your sewer line may be partially blocked, requiring professional assessment.
8. Sewer Line Backups
A sewer backup is a serious issue that requires immediate attention. It often starts with multiple drains clogging at once and can lead to sewage overflowing into your home.
How to Fix It:
- Stop using water immediately.
- Look for signs like gurgling toilets, slow drains, or bad odours.
- Call a plumber ASAP—sewer issues require professional equipment.
9. Burst Pipes
Burst pipes can cause flooding and water damage, often due to freezing temperatures or high water pressure.
How to Fix It:
- Shut off the main water supply to stop further flooding.
- Drain remaining water by turning on taps.
- Wrap the burst pipe in a pipe repair clamp as a temporary fix.
Professional repair is required to replace damaged pipes.
10. Strange Noises in Pipes
Banging or rattling pipes can be caused by loose fittings, air pockets, or high water pressure.
How to Fix It:
- Secure loose pipes with brackets.
- Release trapped air by turning on all taps for a few minutes.
- Install a water hammer arrestor if the issue persists.
Plumbing problems are bound to happen, but being prepared can make all the difference. Whether it’s a simple fix like tightening a tap or a more serious issue like a sewer backup, knowing what to do—and when to call a professional—can save you time, money, and stress. If any of these issues feel out of your depth, don’t hesitate to contact a licensed plumber.
