A white diverter body for a 2 x 3 downspout

The Oatey Mystic Rainwater Collection System gives a residential downspout a dedicated collection point for rain-barrel filling. The white housing mounts into a 2 x 3 downspout and the hose carries collected water toward the barrel.

It fits a garden route where the downspout is close to a bed, patio container group, side-yard watering spot, or small utility area.

The layout depends on clean alignment

Rain-barrel diverters work from placement. The barrel inlet, hose, and downspout opening need a clear relationship so water moves into the barrel cleanly and the station stays easy to inspect.

Mark the downspout carefully, place the barrel on a firm base, and keep the hose visible during early rain checks.
