In our homes, there are different kinds of water systems and sewages that have overflow pipes or overflow systems. Sometimes they can leak because of the water overflow on them. Here, we will explain the general causes that the overflow takes place. And you can find the general solutions for them to these systems. General systems that have water overflow pipes;
- Toilet cisterns,
- Sinks,
- Cold water feed and expansion tank,
- Central heat feeding
- Copper cylinder
- Boilers
You can find all the problems and solutions that are related to these systems that you have in your home. Different kinds of these systems can make water leak into your home. So you need to identify which system leaks water from it.
In general, if the floor of your bathroom is filled with water, you need to check the toilet overflow. And also if the water comes from the top of your home, you probably have a problem with the central heat feeding, copper cylinder, and boiler.

Water Overflow Problem in Toilet Cisterns

Toilet cisterns are very important systems that provide water to clean up the toilet. And there is an automated system that drains and fills the cistern with water. Also once you push the button of the toilet cistern, it flushes the water inside the cistern. And the cistern automatically fills with water.
And also there is a water overflow pipe that extends from your cistern to the sewage system that you have. If the water level exceeds the overflow pipe level, the water will overflow over the cap of the cistern.
If there is a water overflow from the toilet cistern, you probably have a problem with the toilet cistern water overflow system.
Check the Float Valve
Float vaşves are important parts of the toilet cistern systems. If there is a water overflow from your toilet cistern, you need to check if the float valve works well or not. Float valves are the valves that have a plastic balloon that floats at the top of the water in your toilet cistern. And it is lined with a water valve that provides water in your toilet cistern. Once the water level reaches a specific level, the float valve closes the valve with the lifting force that the water provides.
Before applying the solutions below you need to drain the water inside the toilet cistern. To do it, you need to close the water feed inside the toilet cistern from the isolation valve that provides water. And also, you need to drain the water inside the toilet cistern by using a bathroom tap. After that, you can deal with the float valve system that works well.
So, there is a link between the floating balloon and the valve. The length of this link is very important to define the water level. If the length is more for the water level, you can decrease the link length by bringing the length of the link below to the water overflow level.
And also, there can be a problem with the float valve balloon. If the floating valve is damaged because of some effects, it can fill with water. So, the float valve can not do its job properly. So, you need to change the flow valve system in your toilet system.
The last one, the link may be made from the metal link system. If there is a tangling of the chain in the drain water, you need to check the general link system and solve this tangling to work the float valve.
Water Feed Pressure
Maybe, the water feed pressure is very high to prevent the working of the float valve. And the float lifting force can not close the valve because of the very high pressure of water feed inside the cistern. So, you need to decrease the water pressure by adjusting the isolation valve to a specific degree. And check if the float valve works well in this condition. After that, you can easily make different adjustments.
Float Valve Washer
Maybe the problem is with the washer of the float valve. If the washer of the float valve is damaged during that time, you need to change it. Because the valve working well but the water is leaking through the valve system because of the poor washer. You need to buy a washer and change the washer of the float valve.
It is very basic to do. You just need to detach the valve from the cistern and replace the old plastic washer with the new one.
Float Valve Replacement
This is the last chance that you need to try. If there is complete damage on the floating balloon and at the floating system that the float valşve has you need to change the float valve system completely.
Water Overflow Problem with Taps

Taps are armatures are the general systems that we are using to reach the water. And there are piping and plumbing systems that provide water to the taps and the armatures that we have in our kitchen and our bath.
Detecting the water overflow in the kitchen is easy. Because the only water system that the kitchen has is the dishwasher machine water feed and the kitchen tap. If there are problems with the kitchen tap, you need to check if the washers are the problematic parts in your kitchen. So, you can easily understand if the problematic part is the kitchen tap.
Change Tap Washers
First of all, you need to clean the water feed from the main vein of your home. And change all the washers of the tap that you have. And test it by opening the vane.
Change the Taps
If changing the washers is not working well to cut the water overflow, probably the essential sections of the taps can be corroded over time. If you change the tap system, you will not have any problem with the water overflow.
Decrease the Pressure of Water Feed
Maybe the pressure of the water feed is very high for the general tap and faucet system that you have. You need to check the water pressure from the pressure clock of your home. If it is high, you need to decrease the water pressure by using the vane.
Dishwasher and Laundry Machine Water Overflows
These are the two important machines that we are using in our homes. They both have water feed from the backside of them. And you have a special piping system for these two machines.
If the water connection to these systems is not well, they will have water overflow and water leaks to the ground. To understand it, you just need to examine the water overflow coming from your machines.
And these overflows can be very hazardous for machines that you have. And these machines will not work well.
Check the Connections
Maybe a basic tightening can solve your problems in general. You just need to tighten the connection of the dishwasher to the laundry machine to prevent any leaks.
Change the Connections
Over time, maybe the connections that your machines have can be corroded and lose their work. And you need to change these water connections with the new ones. These parts are generally low in price and standard parts. You can change them by following these steps in general;
- First of all, you need to close the water feed from the main vane that you have.
- Unplug the machine from electricity in terms of safety.
- After closing the water feed, you need to detach the connection that your machine has.
- And attach the mater connection with the new connection that you buy for your machine. So it will be very easy for you to use the machine.
- Test the machine by opening the main vane if it is leaking or not. So, you can easily understand that the connections are working well.
Toilet Sink Water Overflow Problem
In the water overflow system of the sinks, there is a small hole right up to the main drain hole of the sinks. And this hole connects with the main drain hole at the bottom o the sink that you have. If the water level exceeds that water overflow hole of your sink, probably there is a clogging or other problem with your sink in general.
And also, if the water overflow pipe is leaking from your sink, you need to open the sink bşlokage that you have. There are different ways to remove the sink blockage.
Apply Special Blokage Acids
In the market, there are different kinds of sink blockage acids that you can use for the sink that you have. You are adding hot water after pouring this acis into the water overflow system of the sink that you have. The acid melts the blockage and the water overflow system opens.
Apply Blokage Pumps
Also, you can apply blockage pumps to your sinks. You just need to apply these blockage pumps in a good way. Apply the force and push the blockage filth into your sink system.
If this two solution to solve the blockage of your sink does not work, you need to work with professional people to open that blockage. Because the material of the blockage is very stubborn and you can not solve with the conventional solutions.
Water Overflow Problem with Central Heating Equipment
There is central heating equipment in your bathroom. You can see it as a tank that contains water inside it. And at the top of this tank, there is a small tank that works as a water overflow. And the piping system from this tank extends to the sewage system of the house to prevent water overflow in your house. So, there can be problems with these systems if you are seeing problems with the water overflow.
Check the Float Valve
Again, you can have a problem with the float valve that you have. So, you need to check the float valve of the tank that you have. The float valve can be stuck in your tank. And you need to adjust the place o the float valve that you talk to.
Check the Copper Coils inside the Tank
If the float valve works well, you need to check if the copper coils are working well or not. The copper coils provide hot water from the boiler to heat the water inside the tank. And if there is damage to this coil, the hot water mixes with the cold water. Soi provides extra water inside the cold water system of your tank. And this leads to a problem with the water overflow from your tank.
If there is a problem like this, you need to check the copper coils and replace them with new ones. You can see if there is a problem with the coils in general. So, you just need to replace them with the new copper coils.
Water Overflow Problem with Boilers
Bıilers are the systems that provide hot water to all the taps and other sink systems in your home. And if there is a problem with the boiler there are safety parts that make their job.
There is a relief valve that boilers have. These relief valves are working as the relief systems for pressure buildup take place with the boilers. And the relief valve releases high-pressure water from the system to prevent any accidents. And most of the boilers are working with hot water in general.
If there is a water overflow problem with your boiler, there are two causes in general;
- The water if too hot expands and overflows from the system.
- The relief valve does not work well as intended.
Decrease the Pressure
To solve the water overflow problem with your boiler, you need to decrease the pressure of the total boiler to prevent any accidents. If you decrease the pressure of the water inside the boiler, there is no need for a safety system that does not work.
And you need to call professionals to take care of the boiler system that you have. In general gas, engineers are looking for problems with the boiler systems in general.
Copper Cylinder Water Overflow

Copper cylinders are also important parts of your home that provides hot water to the plumbing system in your home. So, it will be very easy for you to have a copper cylinder system. And you need to make a water overflow system in your home.
There are generally two causes that water overflow takes place in your copper cylinder system.
Adjust the Temperature
If the temperature of the thermostat is very high for the copper cylinder, the water expands and leads to the problem of water overflow. So, you just need to decrease the temperature of the water from the thermostat. And it will decrease the temperature and pressure to prevent the water overflow problem.
Check the Coils
Also, there are the same coils as the central heating equipment. You need to apply the same measurements with the coils. And if there is a problem with the coils, you need to change the coils with new ones.
