Submersible vs external pumps - which pond pump should I use?
Submersible pumps sit directly in the water—easy to hide, install, and maintain.
External (dry-mounted) pumps sit outside the pond and are ideal for larger systems, especially those with high head requirements or complex plumbing
Choose a pond pump based on the visual impact, access, and performance you need.
What is “head height” and why does it matter for my pump selection?
Head height refers to the vertical distance water must be lifted, plus the equivalent resistance caused by pipe friction or length. As head height increases, flow decreases. For instance, a pump rated 1000 GPH at 0 ft head might only yield 500 GPH at 10 ft. To size for a waterfall, multiply the width of the spillover (in inches) by 100–200 GPH per inch at your required head height
What’s the difference between a pond pump and a fountain pump?
Pond pumps (also called filter pumps) are designed to circulate water to a filter or waterfall. Fountain pumps are made to create decorative sprays and may not be strong enough for filtration.
