Buying and evaluation criteria for a water tank

When buying a water tank, some important criteria should be considered. We have listed the decisive purchase criteria below and explained them in more detail. You should check these features before buying a water tank to find the right product for your needs:

Here are a few tips on the individual criteria:


The size of the water tank is a basic feature that should be determined before buying. Often the space for a water tank is limited, so it is advisable to measure the maximum size of the tank in advance. This will help to narrow down the search somewhat.


The capacity of the various water tanks ranges from 2 litres to 20,000 litres. Of course, it only makes sense to choose a capacity that is actually needed. If the water tank is intended for a camping trip, for example, then a water tank with a capacity of ten to 80 litres should be chosen.


The weight of a water tank should not be underestimated. Of course, it depends on how big the water tank is and what its capacity is, but with a full tank there is already a great load on the area under the tank.


When choosing the shape, the available space is also a major criterion. Before buying, you should consider whether the water tank should be flat, round, rectangular or an individual shape. Round and rectangular water tanks are the most common.


The opening depends on the function of the water tank. Furthermore, the water tank should have an opening of at least 15 centimetres in diameter, so that you can clean the tank easily. In addition, a suction device can be inserted through the large opening so that the water can be pumped out again if necessary.

Suitability for indoor / outdoor use

There are a variety of water tanks to choose from, regardless of whether the tank should be for outdoor or indoor use. However, the type of tank should be adapted to the circumstances of each household and thus it is essential to pay attention to whether the desired water tank allows this.
