Tips On Choosing The Right Fountain Pump
by Apurva
Choosing a replacement fountain pump can be a little difficult. There are different pumps available for indoor and outdoor fountains. Here are a few tips to help you get the right pump for your fountain.
You've probably noticed the abbreviation GPH on your pump. This stands for Gallons Per Hour. GPH is what tells you about the flow rate that your fountain needs for an adequate flow of water. The type of pump that you buy is dependent on the GPH. For example, a tabletop fountain would have a relatively small GPH of 50-100. A larger fountain might have a GPH of 350-570.
You will also need to know the 'head' height and the 'max head' of your fountain. The 'head' height is the distance between the fountain basin and the water release point. The depth of the basin does not affect the 'head' height. You have to measure it from the start of the tube, that is, out of the water to the actual point where the water is discharged. The 'max head' is maximum height to which the pump can push the water up.
Always remember to buy a pump which has a 'max head' that is higher than your fountain. This is because, at its maximum height, the water flow is not strong. For example, if you have a fountain that measures 4 feet from the basin to the water release point, then you need a pump that has a 'max head' of about 5 or 6 feet. This will ensure that the flow of water is still strong enough at 4 feet.
The outlet tube size is also important. Knowing the outlet tube size will ensure that that fountain tube will fit the opening in the new pump. The measurement is the inside diameter of the tube in the water fountain pump.
Most indoor and outdoor fountain pumps come with a WT model number. They have a 3 pin plug. Pumps used exclusively for indoor fountains are the Mini Jet pumps and pumps with a WP model number. These have a 2 pin plug.
Small indoor fountains don't need a large GPH. If you buy a pump that is too powerful, it will result in excessive splashing. Generally, a 10 inch table fountain would need a GPH of 40-70.
Medium sized fountains with a height of about 36 inches need a GPH of about 100-200. Large fountains of over 6 feet need a GPH of about 250-350. The general rule is that once a fountain goes over 12 inches, it is better to buy a slightly more powerful pump. Most fountain pumps, nowadays, have switches that can control the flow of the water. So you can adjust the water flow according to your preferences and requirements.
A good quality fountain pump should last you about a year and with good care and maintenance, should ideally last much longer. But if you do need a replacement pump, then these tips would surely help you out.
