The toilet continues to flush – what can you do now?
If the toilet continues to flush for a longer period of time, this can have a negative impact on water costs over the year. Even if it is a small, barely visible trickle in the toilet. Hundreds of liters of water get into the drainpipe, often unnoticed. If the cistern has lost its functionality, there may be various reasons.
Different reasons for a defective toilet flush
If the water runs continuously into the toilet, then several factors can be the cause.
Dirt deposits in the toilet cistern
Over the years, deposits and dirt in the cistern can increase, which can cause a defect with subsequent flushing. The seals can be displaced as a result, so that the flushing system is no longer fully functional.
Brittle rubber seals
A possible cause of the unwanted trickle in the toilet can be a worn rubber seal. This is exactly positioned at the water inlet and the water outlet. It is located at the opening for the water outlet in the toilet. Such a seal can wear out or slip over the years. The tension is gone and the water no longer has one hundred percent support and flows through.
With the help of a so-called float in the cistern, the subsequent amount of water is controlled. It also controls the water level. If this device is no longer properly seated, then the float no longer rises with the incoming rinse water. The valve is never completely closed and ensures that water continues to flow.
How a cistern works in the toilet
In order to permanently eliminate the defect, you should primarily deal with the functionality of the cistern. Whenever the toilet is flushed, the inlet valve is unplugged. This way the water runs unhindered. Depending on the design, five to nine liters of water can get into the toilet. During this process, the plug is moved downwards and ensures that the seal closes the water inlet again. But of course, these are not the only parts in the toilet cistern. The float is connected to a tap via a lever.
Fix the defect in the toilet yourself?
In most cases, dirt and limescale deposits are the cause. Because these ensure that the water is not completely retained. This is one of the normal signs of wear and tear on a toilet. The focus is on gelled or porous seals or a non-functional filling valve. Before considering a repair, the first step is to do a thorough cleaning. To do this, first, turn off the water supply to the cistern. Usually, this is in the bathroom. But before you disassemble the individual parts from the cistern, you should take a photo of them. So that nothing can go wrong during assembly. But be careful! The cell phone can easily fall out of hand.
Professional cleaning of the cistern
The idea of cleaning the cistern actually only occurs when its function is impaired. And one is relatively amazed at how much dirt can accumulate there over time. In some cases, cleaning brings the running water to a standstill and the toilet flushes properly again. In most cases, lime hinders its function. The mechanism is hampered by limescale deposits. With the help of vinegar and vinegar cleaner in the cistern water, you can successfully combat the limescale and other dirt. Smaller parts such as the water inlet valve can be placed in a vinegar bath overnight or for at least a few hours. But make sure you reassemble the parts exactly.
Renew rubber seals
If the toilet continues to flush, then the seals are probably showing their age. Again, these can be removed and cleaned first. If the cleaning shows no effect, then the seals should be replaced. These can usually be purchased in hardware stores or specialist sanitary shops. When shopping, you can take the broken seals with you for safety. So you know exactly what type it is.
Repair float and float valve
If the water continues to run after thorough cleaning and replacement of the seals, the float and float valve should be considered as the cause. The float shouldn’t be too loose for it to be fully functional. Sometimes it does not sit properly in its place and so the water cannot flow as it should. Perhaps the problem is also with the valve, which no longer closes well enough. This should also be checked. If necessary, it should be replaced. The relevant specialist trade or hardware store has this type of spare parts in their range.
Modern concealed cistern
In modern new buildings, in particular, the cistern is often in the wall. This is covered by a plate to activate the flush. The cistern itself is installed invisibly. This is a special case that can still be cleaned and repaired. If you have discovered a leak in the flush, the cover can be easily opened. The concealed cistern can also be descaled and cleaned in a few simple steps. The parts can also be exchanged just as easily
