Gardena Suction 7 m: Robust Suction Hose for Connection to The Garden Pump with Suction Filter and backflow Stop, Diameter 25 mm (1418-20)

While this is great for moving water from one end to the other, there is a fatal flaw that makes this hose absolutely useless. Unless you prime it first, it floats like a turd in the Seine... I've had to attach a fishing weight to the end of mine to keep it on terra firma. As one would expect it's also unwieldy and has almost taken my head clean off on numerous occasions trying to unravel it from it's shipped rolled state.
