Decide what type of pump you need for your project: submersible, in-line capable, or low water shut-off.
Submersible fountain pumps need to be kept inside the water basin, fully submerged in the water at all times to avoid pump damage.
Low water shut-off pumps work the same as standard submersible fountain pumps when they are fully submerged in water. When the water levels get too low, the pump will shut itself off. The pump will automatically turn back on when the water levels are restored. These pumps are ideal for fountains located in a sunny or windy area where the water levels can drop without someone noticing.
In-line capable pumps do not need to be kept in water, they can sit below the fountain with a tube running to and from the pump to the fountain. These are perfect for fountains that do not have a large reservoir or a good hiding spot for the pump.
Prefiltration Pumps with pre-filters help prevent debris from getting lodged in the pump. It’s a great feature for pumps located in an area where leaves or flowers may end up in the water.
Be sure to check the area where your pump sits in your fountain. Not all fountains can house large pumps.
TIP: Remember to keep your fountain full of water. Most pumps will burn out if not fully submerged, unless they have Low Water Shut-off
