The risks to drinking water quality from backflow contamination incidents pose a constant threat—whether they’re nuisance, non-health hazards, or serious public health events. Plumbing codes mandate that potable water supplies be protected against backflow at all cross-connections. We offer the largest selection of backflow prevention solutions for any application.

The Armstrong Astro 2 hot water re-circulation system automatically circulates water through domestic water pipes. This ensures that hot water is available instantly at every tap throughout a residence. From a cost and environmental point of view, far less water is wasted each time a hot water faucet is opened – saving an average of 12,000 gallons of water annually for a typical four-person household. Ideal for retrofit applications.
