Flood Pumps are completely oil-free, making them safe for koi and all aquatic life.Q: Can these run 24/7?A: Absolutely. They're designed specifically for 24-hour continuous operation.Q: What does "low head" mean?A: Low head refers to applications where water doesn't need to be lifted very high (typically under 25 feet). Check the max head specifications to ensure the pump reaches your desired height.Q: Can I install the pump horizontally?A: Yes, Flood Pumps can be installed either vertically or horizontally.Q: How do I choose the right size?A: For pond circulation, aim to turn over your pond volume once per hour. For waterfalls, you need approximately 100 GPH per inch of waterfall width. Ensure the max head height exceeds your waterfall or fountain height.
