Waterfall and fountain: the right and the wrong ways


There are lots of misconceptions about how pumps should operate in the garden. Pumps operate in a cyclic way in the pond. When it supplies a waterfall a fair volume of water will be sucked out by the pump at one point and poured back into the pool from the waterfall at another. The widely held notion is that these points should be at the opposite ends of the pool.
