Toilet cistern device
In order to find out the nature of the malfunction and understand how to repair the toilet cistern, you should get acquainted in detail with the device of the drain tank itself.
The scheme of a traditional drain tank device includes:
- external components - tank, lid, release button;
- internal - filling and drain fittings.
Filling valves (sometimes called filler, float) are needed to fill the tank with water while controlling its quantity. And the components of the drain give the descent of water directly into the toilet bowl.
Common faults and solutions
Popular toilet cistern failures include:
1. Continuous water supply directly into the flush tank or into the toilet bowl.
2. Breakage of the trigger lever.
3. Noisy tank filling and more.
Let's consider each malfunction in more detail.
- Constant water supply to the flush toilet cistern
- If water always enters the drain tank, then the reason for this will usually be:
- Float lever tilt. To repair the flush toilet tank in this embodiment, you should determine the lever in the most ideal position.
- Float damage. The component can pass water inside itself, which leads to its inevitable aspiration to the bottom of the container. Today's floats leak very infrequently, as they are made of stainless steel or plastic.
- Float valve failure. Removal - valve replacement. This operation does not require great abilities, thanks to this it can be implemented without outside help.
Valve Repair Tips
-
Flush the toilet tank.
- Using a wrench, unscrew the fitting. It connects the float valve to the water pipe.
- Disconnect the lever.
- Unscrew the fixing nuts - outer and inner.
- Remove the float valve.
- Install the new valve and replace the float arm in its original position (it is best to use the previously removed fixing nuts).
- Run water into the tank.
- Fasten the float lever in the required position.
It should be borne in mind that the valve, which is designed to operate at low pressure and high pressure, also passes water. Even when fully corrected.
Constant water supply to the toilet
If water always enters the toilet, then damage to the siphon membrane is considered the reason for this. To repair the toilet, you need to change it.
Instructions for replacing the water seal membrane
- Fix the crossbar instead of the tank cover and tie the float lever in it.
- Drain the water from the container.
- Unscrew the nuts that serve as the connection between the flush pipe and the tank.
- Loosen the water lock nut.
- Disconnect the water seal from the release lever.
- Replace the old diaphragm with a new one of the same size.
- Assemble the affected fittings in reverse order.
Release lever broken
In such a case, the reason is understandable - the thrust has become unusable. To remove a malfunction, it must be changed to a new one.
Noisy tank filling
To remove this breakdown, you need to install a silencer. The operation is performed by attaching a plastic flexible tube to the float valve. If a good result could not be achieved, a stabilizing float valve with a piston should be installed. It is made as a hollow structure with a special chamber at the end.
Other breakdowns and recommendations on how to repair the toilet
It happens that the toilet tank leaks from the outside - at the point of attachment to the base of the bowl. In this option, it is worth tightening the bolts with which the drain container is fixed to the toilet
But it is necessary to take into account the efforts made, otherwise the bowl platform itself may burst, which entails a complete replacement of the toilet bowl. If flaws in casting are noticed, then it is recommended to lubricate the cuffs with sealant
The suspected problem is a leak that forms at the junction of the hose part with the inlet fitting. Removal comes down to tightening the hose nut. The gasket may need to be replaced.
Summarizing the above material, it must be stated that setting up a toilet bowl is a simple matter. Having basic knowledge of its design features, as well as the tools you need, you can do all the repair work yourself.
How the flush tank works and adjusting its mechanisms
After installing the toilet bowl and connecting it to the water pipe, it is necessary to check that all connections are tight, the liquid is collected to the desired level and drained from the tank completely or half of the capacity. All this can be achieved by adjusting the flush mechanism in the toilet. Before embarking on this process, it is necessary to understand in detail what it consists of. The drain mechanism is adjusted using tools and materials such as:
- wrench;
- pliers;
- fumlenta;
- wire;
- rubber gasket;
- sealant.
Schematic diagram of a toilet cistern.
Currently, many different modifications of toilet bowls and tanks for them have been created, but the principle of operation of the internal mechanism is the same for everyone. The drain device of all modifications is based on a device for draining water and shutoff valves, which consists of an inlet valve and a float. The water supply device is attached to the hole, which is located on the top right or left side of the barrel. A rubber gasket is placed on the inside to secure the valve, and a plastic nut is screwed on the outside.
When liquid enters through the valve, the float rises and, at the right level, presses on the plastic plug with a rubber gasket at the right level. She, in turn, closes the water supply nozzle. To avoid overflow, the float can be adjusted. To do this, its lever must be bent so that the liquid is just below the drain pipe. If the lever is made of plastic, then it is provided to be adjusted with a ratchet or a fixing screw.
In some flush tanks, water constantly flows into the sewer through the drain pipe and cannot rise to the desired level, of course, and the float cannot rise to the required height. This happens when the seal is worn out a little, and because of this, the seal is broken. You can eliminate such a malfunction with the help of a simple device - a small load, for example, a nut.
Scheme of the drain mechanism 3/6 l for the toilet bowl.
It is not difficult to assemble such a structure. To do this, the weight is suspended above the outlet on a pear or lever. Such a device helps to achieve not only tightness, but also they can adjust the drain process. When the trigger raises the valve using a button or lever, the liquid begins to drain into the toilet, and at that time low pressure forms in the pipe and, despite strong suction, using a weight, you can stop draining the liquid at any time.
The water level can also be adjusted using the overflow pipe. It is set so that its upper edge is located just above the water level, while the float will be able to close the valve for its intake. Sometimes, due to some defect, liquid is drawn into it, and it cannot perform its function, therefore, in this case, the float must be replaced.
Method for adjusting the water level in an old-style flush barrel
A simple cistern design.
In newer models of this plumbing equipment, it is not necessary to adjust the toilet bowls, since the liquid has already been drained into them by the manufacturer. In modern cisterns, there are two buttons for draining. One serves to completely release water into the sewer, and when the second button is pressed, only half the volume of the tank is consumed.
On older models, in which the tanks are suspended high, the side lever, when draining water, grabs the bell by the ear and because of this, over time, during operation, it can bend or pinch the hinge. In order for such a flushing device to work clearly, the hinge between the lever and the button is fixed with several turns of wire. In this way, a device is made in the form of a fixed lever between the drain mechanism and the riser
With the help of such a device, you can adjust the flow of fluid in the toilet, which is important for economical water consumption.
Using all these simple tools, adjust the cistern flush mechanism so that the toilet works properly and economically.
