The Deviator (Patent Pending)

Close‑up of Product Water Deviator gutter insert with hose connection attached to the gutter face.

The Deviator (Patent Pending) Redefining where rainwater redirection begins. Most homeowners assume rainwater capture begins at the downspout. The Deviator (Patent Pending) introduces gutter-level rainwater redirection as a defined control point within a gravity-based rainwater system. By establishing roof runoff control at the gutter — before vertical descent begins — it repositions where coordination occurs […]
