Pumps & tanks

Size the pump and the tank as a pair. For pumps, provide the flow needed, total head, phase and horsepower, and whether the source is a sump, borewell or mains line. Pressure pumps suit boosting on low-pressure floors. Tanks are stated by capacity in litres, material, plastic or steel, and shape, plus manhole and inlet size where site access is tight. Electrical connection is for a qualified electrician.
