Question & Answers
Product Questions
Product Questions
Question:
How do I choose a fountain?
Answer:
To choose a fountain, first decide if your goal is aeration, aesthetics, or both.
- aeration or both, choose an aerating fountain with higher flow and water circulation.
- aesthetics, consider your visual preferences, ensuring your pond meets depth requirements and the display size fits.
Question:
If I want to buy a fountain, how do I choose the horsepower?
Answer:
Horsepower determines the spray pattern size. Choose based on your pond’s depth, size, and budget. Most fountains fit ponds ¼ acre or larger, but avoid overspray. Select horsepower based on the look you want and what you can spend.
Question:
Do I need to hire someone to install my fountain?
Answer:
If there's no power source near your pond, hire a licensed electrician to install one. Once power is set up, fountain installation is simple: the unit floats, anchors with rope and cinder blocks, and plugs in via a submersible cord. Many customers install it themselves to save money, depending on available resources.
Question:
How do I choose between 110-120V and 220-240V?
Answer:
If your pond's power source is over 70 feet from the main breaker, use 210–240V to ensure consistent fountain performance. Lower voltage at long distances can cause the fountain to run poorly or shut off. Make sure your setup can handle higher voltage.
Question:
Are lights automatically included?
Answer:
Lights are sold separately but can be added anytime. They easily snap onto the fountain and are highly recommended.
Question:
Why is the power cord so expensive?
Answer:
The power cord cost is based on material and gauge size. It uses copper or stainless steel wire, ranging from 14-gauge to 4-gauge, depending on the fountain’s size and cord length.
