How it works The average roof sheds 160 gallons of rainwater per hour during a moderate rain fall. The Garden Watersaver is designed to capture some of this water. Rainwater flows from the roof into the gutter downspout and gets captured in the Watersaver reservoir. When the reservoir, fills the water then takes the path of least resistance which is the units lower exit spout that leads, via a hose, to the rain barrel (container). When this barrel is full, back pressure occurs and the water then exits out of the upper exit spout into the normal drainage system. For full back pressuring to occur it requires no openings on the top of the rain barrel. The kits 7 foot hose allows the rain barrel to be moved away from the building & placed in low visibility areas. (for full back pressuring to work it requires a closed top situation) Note: Will fill 55 gallon rain barrel in 2 to 3 hours during a moderate rainfall.
