Tips for Choosing a Pond Pump

Choosing pumps for water gardens and other features is key to the maintenance of water movement and the prevention of algae buildup. If there are plants, fish, and other aquatic life in a point, it’s crucial to keep water healthy through even nutrient and oxygen distribution. There are two types of pumps, and their selection and sizing will be explained below.

Submersible Pumps

A submersible pump is designed to be completely submerged in the deepest area of the pond. They’re placed in a vault, a skimmer box, or directly into the pond, and they vary in size from 50-5000 gallons per hour. They’re easy to install, which makes them an economical choice for small ponds. If there are fish and plants in the pond, it may be best to choose an oil-free model because of the risk of leakage.

Centrifugal Pumps

A centrifugal or external pond pump is an energy-efficient, reliable option. They’re installed in dry locations near the pond, and they’re best for ponds over 1000 gallons. Compared to submersible pumps, they’re usually louder and more difficult to install, but they’re easier to maintain.

Choosing a Pump

When choosing a pond pump, it’s worth noting that they come with cords of varying lengths. It’s important to ensure that the cord can reach through the pond and to a faraway plug. Depending on the town’s electrical codes, the outlet must be at least six feet away. While it’s not advisable to use an extension cord, if one must be used, be sure it’s plugged into a GFCI and approved for outdoor use.

Pump Sizing

Pond pump sizing is done by gallons per hour at one foot of height or lift; larger pumps get horsepower ratings. To choose the right size pump, a buyer must first determine the pond’s volume by multiplying the length, width, and depth by 7.5.

Pond pumps are a necessary part of outdoor water features, especially when there are plants and animals that need nourishment and oxygen. By considering these factors, homeowners, landscapers, and others building water features will find it easier to choose the right pump for the application.…
