Toilet Flush Tanks: Types, Operation, and Selection
Toilet flush tanks are essential components of sanitary fixtures because they regulate the release of water and ensure hygiene, comfort, and significant water savings. There are different types of toilet flush tanks that fit various toilets and systems, meeting specific aesthetic and functional needs.
Types of Toilet Flush Tanks
External Toilet Flush Tanks
External toilet flush tanks are installed visibly above or behind the bowl and represent the most traditional solution. They are ideal for floor-mounted toilets and allow for simple and quick maintenance since every component is easily accessible without breaking walls.
Advantages: They are economical, easily replaceable in case of malfunction, and do not require masonry work.
Versions: There are backpack tanks (installed just above the toilet) and high tanks (positioned high on the wall and connected by a long flush pipe), still common in renovations of period or service bathrooms.
Concealed Toilet Flush Tanks
The concealed toilet flush tanks are installed inside the wall and are designed to be connected to wall-hung or close-coupled toilets. They are perfect for modern bathrooms because they improve the overall aesthetics, free up valuable space, and make floor cleaning easier. The concealed tank requires a wall with a thickness of at least 8-12 cm. If the wall is too thin, there are specific drywall modules with self-supporting frames.
Monoblock Toilet Tanks
The monoblock toilet flush tanks are integrated directly into the toilet, resting on the back of the bowl. This compact solution is ideal for small bathrooms and ensures a uniform design and easier installation since it does not require complex external connections or wall recesses.
How the Toilet Flush Tank Works: Float and Valve
The operation of the toilet flush tank is based on a precise hydraulic principle: the accumulation of water (usually between 6 and 9 liters) is released into the bowl via a button or lever.
What’s Inside the Flush Tank?
Toilet Float: Regulates the water level. When the tank is full, the float rises and closes the fill valve.
Flush Valve (Battery): This is the mechanism that lifts when you press the button, allowing water to flow forcefully into the toilet.
Installation, Maintenance, and Cleaning
While external tanks are easy to install even with DIY, concealed toilet flush tanks require professional installation by an experienced plumber.
Periodic maintenance of the gasket, float, and flush button is the key to system longevity. For cleaning the toilet flush tank, it is recommended to use gentle descaling products (or vinegar/citric acid) to avoid damaging plastic components and rubber seals.
Water Savings and Dual-Flush Systems
Modern toilet flush tanks with dual buttons allow you to choose between a partial flush (usually 3 liters) or a full flush (6 or 9 liters), reducing water consumption.
How much can you save? A family of four can save thousands of liters of water per year simply by using the small button for liquids. Almost all modern flush valves have adjustable sliders to set the amount of water released.
Dimensions, Compatibility, and Control Plates
Toilet flush tanks are not universal because each manufacturer has its own actuation system and dedicated control plate. It is essential to check dimensions, distance between connections, and compatibility with the toilet, especially for concealed models.
