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.

Industry Leaders: Geberit, Grohe, and Pucci on CeramicStore

When it comes to reliability built into the wall, choosing the brand is not just a matter of prestige but also of availability of spare parts and technical durability. At CeramicStore, we have selected the three global giants who have made the history of flush tanks:

Geberit: The Synonym for Concealed Tanks

Geberit is probably the most sought-after brand by users. The Sigma, Omega, and Delta series are the market standard. Choosing a Geberit tank means being sure to find every single gasket or control plate even thirty years from now.

Pucci: Italian Excellence and Water-Saving Flush

Pucci is the Italian brand that revolutionized the concept of water saving with the famous Pucci Eco series. It was the first company to introduce the dual button, allowing precise water dosing. Pucci tanks are known for their incredible slimness.

Grohe: Design and Quick Installation

Grohe flush tanks are particularly appreciated for the quality of their control plates, which offer durable chrome finishes and an extremely smooth and quiet pneumatic operation.

Why Buy These Brands on CeramicStore?

Discover the full range of toilet flush tanks on CeramicStore, along with original spare parts and accessories compatible with the main brands in the industry. When you buy a Geberit, Grohe, or Pucci tank from our store, you are guaranteed:

  • Original Products: No low-quality compatibles, only certified mechanisms.
  • After-Sales Support: If you have doubts about the compatibility of a control plate or flush pipe, our technical team knows every detail of these brands.
  • Discounted prices and special offers.

FAQ - Drainage Boxes

What is the difference between an external and a recessed toilet cistern?

The external box is visible and easy to install, while the recessed one is hidden in the wall and more aesthetic.

Why is the toilet tank leaking water?

The problem is usually caused by worn seals, a faulty float, or limescale in the internal mechanism.

How do you replace the toilet flush tank?

External cassettes are easily replaced, while recessed ones require a technician's intervention.

What accessories are needed to install a toilet flush tank?

For installation, sleeves, tubes, fastening systems, extensions, and clamps may be needed, as well as any plates and activation buttons.

How to improve water savings with the toilet cistern?

Dual-button flush tanks allow you to choose between partial and full flush, reducing water consumption and improving home efficiency.

When is it necessary to replace the toilet flush tank?

The toilet flush tank should be replaced when it has water leaks, continuous flushing, button malfunction, or worn internal components such as the float and seals.
