One of the central features in many gardens is the fountain. They are soothing, relaxing and beautiful and provide a central focus to the garden. The most critical part of any water fountain is the pump. If the water fountain pumps stop working then you lose most of the charm of the fountain. It does not matter what style fountain you have, in every case the main function of the pump is to take water from the fountain reservoir and shoot it upwards creating the fountain effect.

If you are installing a fountain or replacing the pump in an existing fountain, you will have a hard time choosing the correct pump if you do not know which specifications are most important for the type or size of fountain. The following are two critically important specifications for ANY water fountain pumps.

GPH or "Gallons per Hour" tells you how much water the pump can move in an hours' time. It is important that the GPH is not too high or too low for your particular fountain. In general, a small tabletop fountain needs a GPH of 50-100, a medium fountain up to 3 feet high will need a GPH of 100-200 and a large fountain from 3-6 feet will require a GPH of 250-350. If the GPH is too high, the water will splash outside the fountain and if the GPH is too low, you will not get the proper flow.

Max head is the term used for the unit of measure telling how far into the air the pump can push the water. For example, water fountain pumps with a max head of 4 can push a stream of water 4 feet above the height of the fountain. Ideally, you should choose a max head that is a bit higher than the maximum height of your fountain. If your fountain is 3.5 feet, high you will use a max head of 4 because the strength of water flow is reduced at the top of the fountain.

There are other specifications such as outlet tube size and head height, which can also affect the performance of your fountain, but the two that have been mentioned in detail are the most critical.

Depending on the location of your fountain in relation to the house, you may also want to consider using a solar fountain pump. This way you can use the power of the sun to run your water fountain pump and save yourself the trouble of running electrical wires a long distance.

As you can now tell, choosing a water pump for your fountain really is not hard at all. A little knowledge goes a long way and you do not need too much to figure out which pump will be best for your fountain.
