Toilet cistern volume

Any plumbing makes our life more comfortable. Among other devices, the toilet occupies a special place. Thanks to its practicality, durability and the ability to drain used liquid, this sanitary and hygienic device is so popular. But for normal operation, the product requires special design elements, for example, a drain tank.

It is a reservoir into which a special mechanism is installed to drain water. Using a hose, the required volume of liquid is supplied to it. The size of the container depends on several parameters: the model of the toilet itself, the number of household members and other conditions.

How many liters are in the toilet cistern?

The volume of the drain tank is influenced by several basic parameters. And if previously the size of a product was strictly regulated by GOST, now on store shelves there are products of a wide variety of shapes and sizes. So, tanks for draining water can be:

1. Mounted. These are old models that can only be found in communal apartments. The tank was made of cast iron, after which it was fixed to the ceiling of the bathroom. Despite the material used, the device was not of high quality or reliability.
2. Plastic. They replaced cast iron ones. These are inexpensive models. But the cost directly affects the quality of the tank. Products often fail and require replacement. Therefore they are not in great demand.
3. Ceramic, porcelain.The most popular options. The product is mounted directly on the base of the toilet. The tank is practical and has an attractive appearance.
4. Polypropylene. A more modern version of a plastic product. The walls of the device are thicker, so it lasts longer. Usually it is mounted on the wall, after which it is “hidden” using decorative panels.

If the shape and material of manufacture vary, then the remaining structural elements remain unchanged. This greatly facilitates independent repairs if necessary. So, the tank consists of the following elements:

• water collection and drainage mechanism;
• valve for water intake.

The size of the tank itself is individual and depends on the manufacturer. So, according to the old GOST, at least six liters of water should be placed in a standard size drain tank.

Containers of various sizes are now available for sale. For example, you can find larger tanks with a capacity of 10 liters. As a rule, they are equipped with two buttons, allowing you to use only half the volume at a time.

Reference! The water drain tank was invented in 1777 by London watchmaker Alexander Cumming.

What is the optimal volume of a toilet cistern?

When choosing a suitable size drain tank, you need to take into account the number of household members and how often the plumbing fixtures will be used. So, for a family of one person, a small tank of 5-6 liters is quite enough. If there are a lot of household members, then you should give preference to larger models of 9-10 liters. Of course, the cost of such products is higher, but thanks to the half-flush system, the device is more economical to use.

In addition to the volume, you need to pay attention to the quality of the tank and mounting option.After all, any plumbing fixture is an expensive purchase that you will use for many years.
