Common Causes of a Leaking Toilet
If you notice water pooling around your toilet or your cistern constantly running, you may have a leak. Here are the most common reasons:
1. Flapper Issues
The flapper is the rubber valve at the bottom of the toilet tank that controls the flow of water into the toilet bowl. If the flapper is worn or broken, it may not create a proper seal, allowing water to leak continuously from the tank into the bowl.
2. Faulty Fill Valve
The fill valve controls the water flow into the tank after each flush. If it’s faulty or malfunctioning, it can cause water to leak from the tank or result in the toilet running constantly.
3. Leaking Toilet Cistern
A leaking toilet cistern is often caused by a broken or cracked cistern. This can result in water pooling around the toilet’s base or onto the floor.
4. Bowl Damage
Damage to the toilet bowl itself, such as cracks or chips, can lead to water leaking. Cracked bowls should be replaced to prevent further water wastage or floor damage.
5. Cracked Supply Line
A cracked supply line can cause water to leak from the area where the line connects to the toilet’s tank, potentially leading to flooding or pooling water.
6. Loose Bolts
Loose bolts that connect the toilet tank to the toilet bowl can allow water to leak between the two components. These bolts should be tightened or replaced to prevent any leaks.
7. Rusted Pipes
Over time, pipes can corrode and develop rust. Rusted pipes, especially around the toilet area, may weaken and begin to leak. Replacing these pipes can stop the leaks.
8. Broken Tank-to-Bowl Gasket
The gasket between the tank and bowl seals the two components. If the gasket is damaged or worn out, it can lead to leaks at the point where the tank connects to the toilet bowl.
9. Condensation
While not a true leak, condensation can form on the exterior of the toilet tank, especially in humid conditions or when the temperature changes drastically. This can cause water to appear on the floor around the toilet, mimicking a leak.
10. Damaged Wax Ring
The wax ring provides a seal between the toilet and the floor. If the wax ring is damaged or worn, it can lead to leaks around the base of the toilet. Replacing the wax ring can eliminate the leak.
11. A Damaged Seal
A damaged or worn-out seal between different parts of the toilet, such as the tank and the bowl, can cause water to leak from areas where it should remain watertight.
12. Cracked Toilet Bowl
A cracked toilet bowl is a significant issue. Even small cracks can lead to water leaking, which may worsen over time. A cracked bowl should be replaced to prevent leaks and further damage.
13. Damaged Tank
A damaged toilet tank, whether from physical impact or age, can lead to leaks. Cracks or splits in the tank can allow water to seep out, causing water damage to the surrounding area.
14. Drainage Problems
Issues with the drainage system can cause water to back up into the toilet, leading to leaks or overflow. Blockages or improper drainage need to be addressed by a professional plumber.
15. Damaged Toilet Tank
A damaged toilet tank can result from physical impact, wear, or manufacturing defects. Cracks or holes in the tank will cause water to leak out, leading to water damage and increased utility costs.
16. Faulty Float Valve
The float valve controls the water level in the tank. If the float valve is malfunctioning, it can lead to overfilling of the tank or constant running of water, which can result in leaks.
17. Worn-Out Flapper Valve
The flapper valve controls the release of water into the bowl. Over time, the flapper valve can wear out and fail to seal properly, leading to water leakage from the tank.
18. Bad Float
A faulty or misadjusted float can cause the water level in the tank to rise too high or fail to stop completely. This can lead to water spilling over or leaking from the tank.
19. Broken Wax Seal
The wax seal between the toilet base and the flange is crucial for keeping water from leaking out. A broken or deteriorated wax seal can cause leaks around the base of the toilet.
20. Misadjusted Flush Valve Assembly
If the flush valve assembly is misadjusted, it can cause water to leak from the tank into the bowl or onto the floor. Ensuring the flush valve is properly adjusted can resolve this issue.
21. Misaligned Fill Valve
A misaligned fill valve can result in improper water flow into the tank, causing water to leak out or the toilet to continuously run. Proper alignment is necessary for efficient operation.
22. Misaligned Valves or Pipes
Misalignment of pipes or valves can lead to leaks and water wastage. Regular inspections can help prevent this issue, ensuring that all connections are secure and correctly aligned.
23. Problematic Water Shutoff Valve
A faulty or old water shutoff valve can cause leaks at the base of the toilet. If the valve is not working correctly, it may lead to leaks around the supply line or tank.
How to Identify a Leaking Toilet
Not all toilet leaks are obvious. Here are some simple checks you can do:
- Dye Test: Add a few drops of food colouring to the cistern and wait 10 minutes. If colour appears in the bowl, you have a leak.
- Running Water Sound: If you hear running water when the toilet hasn’t been flushed, there may be an internal leak.
- Higher Water Bills: A sudden spike in water usage often signals an undetected toilet leak.
- Damp Floors or Mould: Water pooling around the toilet base can indicate a hidden leak.
If you notice any of these signs, contact us for professional leaking toilet plumbing services.

Common Areas Where a Toilet Might Leak
A toilet can leak from several points, and identifying the source is crucial for an effective repair. Here are the most common areas where a toilet might leak:
1. Base of the Toilet
Water pooling around the bottom of the toilet often indicates a failed wax seal or loose bolts securing the toilet to the floor. If not fixed, this leak can damage flooring, encourage mould growth, and weaken the subfloor.
2. Cistern (Toilet Tank)
Leaks from the cistern (toilet tank) usually result from worn inlet or outlet valves, cracks in the tank, or faulty seals. These leaks may cause constant running water or dripping down the outside of the cistern.
3. Flush Pipe Connection
If water is leaking behind the toilet, the flush pipe seal may be deteriorated. This pipe connects the cistern to the bowl and, when worn out, can cause slow leaks that go unnoticed until significant damage occurs.
4. Inlet Valve & Water Supply Line
Leaks from the inlet valve or water supply line often appear as dripping water where the hose connects to the cistern. A loose or damaged hose, corroded fittings, or a faulty shut-off valve can be the cause.
5. Inside the Toilet Bowl
A silent leak inside the toilet bowl is usually caused by a worn flapper valve or faulty flush valve. This allows water to seep from the cistern into the bowl continuously, increasing water bills and reducing flushing efficiency.
6. Between the Cistern and Bowl (Close-Coupled Toilets)
In close-coupled toilets, where the cistern sits directly on the bowl, leaks can occur from the rubber coupling seal between these two parts. If this seal deteriorates, it can cause water to drip down the back of the toilet.
