Aqua-Motion’s Aqua-Flash hot-water recirculation system offers instant, comfortable 90° F water at the sink and does not require power at the sink. The pump installs directly on the hot-water tank, and the built-in timer runs the system only when hot water is needed. It features a rugged valve, stainless/bronze construction, large water passage to prevent calcium buildup, and no screens to become plugged — and it saves up to 12,000 gallons of water per year. Models are available for tank, tankless and combi heaters. Aqua-Motion
