For a fountain to pump water, it needs a good quality water fountain pump. Although there are different types of pump, the operation is much the same, circulating water. As the water is moved by the pump, it keeps the water oxygenated, which is needed by fish, can help keep algae from building up, and it actually keeps the odor down. For this reason, you will find that all water fountains use some type of pump.

When choosing a water fountain pump, you need to be sure you choose the right one. Therefore, you need to understand the flow rate for the type of fountain you have, which is the amount of gallons pumped per hour. Abbreviated as GPH, this flow rate is what is needed to produce adequate water flow for your fountain. Next, you need to consider head height, which is the distance between the fountain's basin and the discharge point of the water.

The goal here is to choose a pump with a maximum head that is higher than the fountain height. In other words, if you have a fountain that is two feet from the level of the water in the basin go the discharge point, you want a pump with a maximum head of at least three feet. Additionally, the tube outlet size is important, which is the part of the pump that connects to the tubing included with your water fountain.

If you have a small, indoor fountain, then you would not need a very powerful pump. In fact, if you go with a pump that is too large, you will only end up with splashing water. Therefore, if you go wit a tabletop type fountain that measures up to 10 inches, you would want a pump with a GPH of 45 to 65 to move the water but not splash.

For medium sized water fountains, anything up to 36 inches tall, whether a tabletop, wall, or floor design, your pump should have a GPH of 100 to 200. Keep in mind that a pump 12 inches tall or more work best with a pump that has a little more pressure than not enough. Then for the large water fountains, the type of pump needed varies. For example, the rule of thumb is that for every inch of stream width located at the top of the fountain, you would need a pump that is capable of delivering 100 gallons of water every hour.

Additionally, remember that for every three feet of fountain height, the pump should provide 500 GPH. Of course, if the fountain is located in an outdoor pond holding hundreds of gallons of water, then the pump should be able to produce as much as 2,000 GPH. If you have a large wall or floor type of water fountain, one that measures up to six feet tall, then you would choose a pump that can pump between 250 and 345 GPH.

In other words, determine the specific needs for the type of water fountain you have so you can choose the pump that will produce the nicest appearance and sound while being the most effective. If you have any questions, you can work with your local gardening center, allowing them to guide you through the pump buying process.
