Proper Water Pump Selection is Important!
Selecting a pump can be confusing but it is critical that the proper pump is chosen to ensure longevity and trouble free performance. Following are several things to keep in mind when selecting a pump:
How much volume do you need?
It takes approximately 36 gallons per minute to make a waterfall 1’ wide x 1’ deep (1’ deep water is considered an average depth for residential applications). The first step in determining how much water you need is to multiply the width of the waterfall in feet x 36 = gallons per minute needed to make 1” thick water over your falls.
Example: A 3’ wide waterfall would need 108 gallons per minute to be 1” thick.
This determines how much volume you need.
Next, determine how much head (lift) there is from the surface of the pond to the top of the waterfall. On a small, simple waterfall the vertical lift is all you need, however on large applications you also need to factor in friction loss form the pipe as well as each fitting to get the total head.
This determines head pressure
Now that we know water volume needed and the head height it is needed at, it makes selecting a pump much easier. Start by looking at our chart below, this chart lists all of EasyPro’s most popular submersible pumps. Look in the yellow box on the right side of the chart – find the column of head closest to your application then follow that column down until you find a pump that delivers the gallons per GPM you need.
If you have a unique application, are using an external pump or just want our help please don’t hesitate to call. Improper pump applications the leading cause of pump failure – we want to help you select the best pump for your application.
Knowing the application and selecting the correct pump for the job will increase the overall performance of the feature and decrease the frustration of frequent call backs and being an unhappy customer.

EasyPro External Pumps
EasyPro offers a variety of external pumps in both non-priming and self-priming styles. External pumps offer several advantages over submersible pumps including reduced energy costs and longer average life span.
Non-priming pumps are best used in flooded suction applications. This means the pump sits below the water level it is pumping. Example would be alongside of a fish tank or in a pump chamber buried alongside of a pond. These pumps can sit above the water level, however, a check valve must be used on the end of the suction line to keep the pump primed.
Self-priming pumps have the capability of purging some air form the suction line and priming themselves (after filling the pump with water the first time). These pumps can sit above the water level without a check valve in the suction line, however, using a check valve speeds up the priming process and ensures a quick flow when the pump is plugged in.
Following is a comparison chart between our most popular external pumps. Use this chart to help select which pump is best for your application. Start by finding the feet of head column on the right side of the chart. Look down the numbers under the feet of head in your application to find a pump that provides the amount of water needed.
