With spring approaching and outdoor decorations piling up in storage, you might be thinking about getting your favorite outdoor water fountain dusted off and inspected.
If you still love the water feature, but have found that the pump is no longer working, replacing the pump is an easy solution! You simply need to find out which type of pump you need as well as the size to bring your outdoor water fountain back to life.
Types of Fountain Pumps
The first thing to consider when replacing the pump in your fountain is whether you want an electric pump, or a solar pump.
Electric pumps with a 3-prong or 3-pin plug can be used in indoor or outdoor fountains. Pumps with a 2-prong or 2-pin plug are intended for use in indoor fountains.
Some electric pumps come with an on/off rocker switch and some are operated by simply plugging and unplugging the pump.
Solar pump/panel kits with battery packs: These kits often include a fountain pump that goes in the fountain and a cord connects the pump and plugs into the solar panel.
The solar panel has a battery pack attached or built into it. Place the panel in direct sunlight to charge the battery pack.
This type of pump will operate the fountain via solar energy during the day.
Then, if you want to run your fountain at night, the battery mode will operate the fountain when the sun goes down.
Solar pump/panel kits without battery packs: These kits include the pump, necessary cords, and solar panel.
To use, you place the pump in your fountain basin, connect the cord to the solar panel, and place the solar panel in direct sunlight.
The panel will not store solar energy so the fountain will only operate when the panel is in direct sun.
What Size Pump Do I Need for My Fountain
There’s more to selecting a fountain pump than just choosing the type of pump you’ll need. Water fountain pumps are sized by their flow rate and pressure requirements.
What’s GPH and How Many Do I Need For My Fountain?
GPH measures the number of gallons of water per hour a pump will circulate.
According to hunker, you can measure this by taking the diameter of the fountain spout and multiplying that by 100. For example, a smaller outdoor fountain with a 1-inch diameter spout will need a pump that has at least 100 GPH capabilities.
Determine the Maximum Lift or “Max Head” For Your Fountain
The maximum lift or “max head rating” is the height of the fountain from the pump to the fountain head or spout. This indicates the measurement at which the pump will need to push the water to reach the spout or head. Once you have the measurement, choose a pump that is at least 1.5 times the head height.
So, if a fountain has a head height of 40 inches, you will want to choose a pump that has a maximum lift of at least 60 inches or more to ensure strong water flow in and out of the fountain. If you are afraid that the pump may be too strong, you can also get a flow reducer to slow the flow down or purchase a pump with flow control to put on a lower setting.
Alternately, if you know you want a slower trickle-type flow for your fountain, you could purchase a pump for a shorter head height (like a 50-inch head height for a 40-inch head height).
Ensure that the Water Pump Tubing is the Correct Size
The size of the outlet on the pump, where the fountain hose attaches to, is called the “discharge size”.
You’ll want to double check the size of the outlet will fit with the fountain’s tube, or if the pump comes with tubing, that the tubing will fit with the fountain’s spout.
Please note, sometimes pumps will include adapters that will make them more universal with fountain hoses and those make it easier to ensure a proper fit.
Bring Life to Your Fountain with the Perfect Size Water Pump
The perfect size water pump will help increase the lifespan of your favorite indoor or outdoor water fountain.
By simply taking a few measurements to calculate the needed GPH, maximum lift and discharge size, you’ll be well on your way to enjoying your water feature.
