Astro 2 hot water recirculation (HWR) pumps from Armstrong Fluid Technology can help save a typical family over 12,000 gallons of water per year by eliminating waste that occurs when occupants open a hot water faucet and have to wait for hot water to reach the fixture. They are suitable for use in a three-pipe installation with a dedicated return. The Astro Express 2 System includes the Astro Express LF Valve and is designed for use in a standard residential two-pipe installation. A large, easy-to-service electrical enclosure includes an integrated timer assembly. A timer accessory kit can be used to upgrade earlier versions. Easy field assembly reduces installation time. They are available in stainless steel and bronze versions, with either NPSM Union or sweat connections. 800/356-9845; www.armstrongfluidtechnology.com.
