Choosing a Water Garden Pump
A water garden pump is an essential part of most backyard ponds. The pump re-circulates the pond water and powers water features such as fountains and waterfalls.
There are basically two types of pond pumps to choose from - externally
mounted and submersible.
External pumps
were traditionally used in water gardens. They sit outside the pond,
with a hose that leads from a strainer in the pond to the pump. From
there the water is forced either to a waterfall, stream or fountain.
Because
external pond pumps are often noisy and require extra plumbing, they
are usually not suited for most backyard ponds. Due to easier
accessibility and ease of repair, however, external water pumps are
often the best choice for larger water gardens and public installations.
Submersible water pumps
are usually preferred by most do-it-yourselfers. They sit underwater
where they are quiet and unseen. These pumps are easy to install,
require no priming and stay cool thanks to the surrounding water.
Submersible
pumps draw water from the bottom of the pond, either through a strainer
or biological filter. A hose attached to the outlet then feeds water to
whichever water feature you have installed.
