Rainbow

Rainbow is one of the most familiar names in everyday pool maintenance. The brand traces back to Rainbow Plastics of El Monte, California, whose leaf rakes, brushes, vacuum heads, and chemical feeders became fixtures on service trucks across the country. Rainbow joined the Pentair family through Pentair's 1999 acquisition of Essef Corporation, and today the Rainbow line is made and supported by Pentair, a global leader in pool equipment. You almost certainly know the classics: the Rainbow 320 automatic in-line chlorine/bromine feeder, the Rainbow 330 floating chlorinator, and the garden-hose-powered Leaf Eater and Leaf Master debris removers. These are simple, dependable tools that have kept pools clean and sanitized for decades — and because they're backed by Pentair, replacement parts and support are easy to find.
