How to Repair a Leaky Toilet Filling Valve
The flapper may be broken
What is a flapper? It is the device in the toilet tank that allows water to flow into the toilet bowl. Over time, they can easily wear out and become ineffective in their task. For this reason, this is one of the most common causes of toilet leaks.
Defective flush valve
If the flapper has been repaired or replaced and the toilet continues to leak, there may be a problem with the flush valve. The flush valve facilitates the passage of water from the tank to the bowl for ‘flushing’. A leaking flush valve can make water drip for a long time after flushing.
Defective fill valve
Another common cause of toilet leakage is a problem with the fill valve. The fill valve (of course) is the fitting that fills the tank from the supply line. A leaking fill valve can cause water to spill onto the floor and form small puddles.
The problem is recognisable by the sound it makes (as if the toilet is running continuously), even if you have not flushed the toilet recently. A simple method to assess whether the toilet leak is caused by the fill valve is to pour food colouring into the toilet tank and see if the water in the bowl takes on the same colour.
Damaged gasket
Damage to the watertight seal at the base of the toilet can be another problem that causes leaks. If leaks occur on the floor, the wax seal may be punctured or worn. To solve this problem, the toilet must be completely removed, so it is advisable to contact a professional plumber.
Leak in the sewer line
Often the worst-case scenario is that your leaking toilet is the result of a leak in the sewer line. If you suspect that this is the case, you should contact us. This type of leak can turn into a much more serious problem, so you need to act quickly to avoid major damage to your property.
Crack in the toilet base or tank
If the leak occurs due to a crack in the toilet bowl or tank, it could mean that water is leaking directly into the floor. This water leak can potentially cause significant damage to the wood, tiles and potentially the subfloor under the toilet. This is another reason why it is essential to contact a specialist to investigate the problem, as a small leak could turn into a much bigger problem if left unattended.
