Every few years breaks my pond pump. You have to pump the water to an approximately 7 meters from Cairns (= source). I have so far bought normal drainage pumps with about 7000-10000 liters. Flow rate per hour. These cost between 40 and 70 euros, if you take not the cheapest nor the most expensive. It's just annoying that these pumps probably not designed for continuous operation (from April to October, 10 - 24 hours per day) are suitable. So they either go broke or - like the last - are so loud that the sound of water is drowned. By chance I discovered the Jebao pond pump. The unconventional design and the cast, watertight engine brought absolute peace in my pond. I can only hear the soothing murmur of the water. When algae and / or plant residues, the pump must be cleaned once under the hose, otherwise they run (for me after about 4 Mnaten) so far since May 11 hours a day from un an. Now is the winter break and I am sure that they will confidently do their job in the coming year. By the way my previous pump ID usually had 350 Watt power consumption, accounting for a significant double-digit Euro amount each month. The 115 watts of Jebao cost me only one-third of electricity, making it easy bet in a few months, the slightly higher cost ;-)
