Polyethylene under-stair tanks are one of the most widely used types of tanks. The application of this category of tanks is to maintain and store the drinking water. The unique design of the under-stair tanks provides the installation of these tanks in the empty space below the stair. People usually purchase and install a under-stair tank for reasons such as lack of interest in the tank visibility, lack of access to a suitable space to install the tank, impossibility of installing the tank on the roof, etc. However, for people, who are going to buy and take an inquiry of the water tank price (get quotation) and to install a under-stair tank, the question arises, how to select a suitable under-stair tank that meets all our needs?

 

Important Points in Selection of a Under-Stair Tank

You should pay special attention to some points in order to choose the best under-stair tank. For example, paying attention to things such as the tank material, dimensions of the space below the stair, volume of the tank required, number of layers of the tank, the tank quality, etc. are among the most important things in selection of the under-stair tank. We will investigate each of these points in the following.

Tank Materials 

In order to know how to choose the right under-stair tank, we must first know about the tanks’ material. The polyethylene under-stair tank is the best type of tank in terms of material. Sometimes it happens that some people place the order for metal tanks to store water.

But you should know that the use and installation of metal tanks is no longer common due to many reasons such as heavy weight, difficulty of transportation, high price, difficult installation, etc. and polyethylene tanks, which have the features such as affordable price, light weight, high durability, etc., are being used instead of them.

Dimensions of the Space below Stair

Be sure to consider the available space before purchasing a under-stair tank because it has been observed in some cases that people mistakenly buy a under-stair tank whose dimensions are larger than the dimensions below the stairs. Therefore, please measure the installation location of the (under-stair) tank before buying the under-stair tank. Please refer to the experts of the complex to inquire about the water tank price.

Required Tank Volume

Another important point to know how to select the right under-stair tank is to pay attention to the required tank volume. A water storage tank should be considered for 12 hours of consumption, 150 liters per person per day in buildings with more than 4 floors or 10 apartment units according to the 16th Article of the National Building Law. It is possible to obtain a proper estimate of the volume of the tank needed for the building according to this law.

Number of Tank Layers

One of the reasons why polyethylene tanks have different types is the variety in the number of layers of this category of tanks. Tabarestan polyethylene tanks have different types such as single-layer, three-layer and four-layer and the difference between them is the presence of a black middle layer. This black layer, which is available in three and four-layer types, is responsible for preventing light from entering because light is the main cause of algae growth in tanks. The experts usually recommend the use of three-layer and four-layer polyethylene tanks for maintenance and storage of drinking water in buildings, etc.

Tank Quality

The tank quality is one of the most important points in its purchase and installation. To better understand this issue, please pay attention to the fact that polyethylene tanks are divided into two categories in terms of quality and raw materials used in their production. The first category includes tanks that are produced using high-quality raw materials, and the second one includes the ones that are produced using recycled materials.

The second category or recycled tanks have a much lower quality than the first one. Unfortunately, it has been observed in some cases that profiteer people have offered second-hand or recycled tanks to customers under the name of new tanks. It is better to buy tanks from reliable producer companies and complexes to avoid this.
