Water pump buying guide

A water pump has several uses. Not only can it be used in the garden, but the truth is that you can do so much more with it in more places: garage, kitchen, even in the bathroom. But, to approach it, the first thing is to know what to look for to buy a suitable one.

And in this we can help you because we have reviewed some characteristics that they must have and which are the differences between the models. Want to know what data is important? These:


One of the first pieces of information you should look for in all water pump descriptions is the capacity they have. That is, the amount of water that can accumulate inside.

In this case, you can also find models that allow you to connect the water hose, so that your tank has a capacity of x plus the possibility of using it without having to fill it first and thus be able to work longer.

Depending on how you use it and how long you need it, you will need one with more or less capacity.


The next point to consider is the type of water pump. In the market you will find outdoor pumps, which are the most common, but there are also indoor ones, even submersible ones (these are used in case of flooding to evacuate the water outside) .

There are others that are not as well known, such as recirculation, well, pressurization or waste water.

What does the choice of one or the other depend on? Basically the use you are going to give it.


How do you want your water pump to work? You can find different types of energy in the market, such as gasoline, cable (electricity), batteries, solar energy…

Again, the choice will largely depend on how you use it. If it’s sporadic, you can opt for electricity or even gasoline or solar power. If it’s more often, the battery gives you more freedom.


There are many powers. Normally, for a “homemade” water pump, it’s not very high, but it’s true that it’s practical to know how to calculate it according to what you need.

For this there is a formula to take into account. It is the following:

Power Required = (Pump Flow x Pump Pressure) / Total Performance

But since we don’t want you to have to calculate formulas, this guide can serve you much better:

  • If it is for a house, the power must be between 2000 l/h and 7500 l/h.
  • If it is an irrigation installation, then it is necessary to take into account the diffuser they carry. And these will be between 540 and 900 l/h depending on the grades you apply.


Finally, we should talk about the price of a water pump. And it is that a water pump for an aquarium is not the same as for a pond or for more intensive use.

You can find those in the aquarium from 20 euros; the most common can be from 40 euros, but the professionals who can really be worth it will be above 70.
