A high pressure water distributor for downpipes. The distributor includes a tube made of a flexible or rigid material having a water tight base and an outlet port. Rain water that is directed into the downpipe is accumulated in the tube and generates a pressure head. As a result of this pressure head the velocity and discharge volume of water from the outlet port increases substantially. The discharged water can be directed through a conventional garden hose, which may be connected to a sprinkler or similar device or the water can simply be conveyed to a remote location from the foundation of the dwelling.
