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 in the rainfall pathway without altering hydraulic reality.
Rain falls across the roof. Gutters collect it. Downspouts carry it vertically toward the ground. When storage is added, water is typically intercepted somewhere along that vertical path — after descent has already begun. That sequence has become the default model:
Roof → Gutter → Downspout → Then Capture.
The Deviator Shifts That Control Point
Rather than waiting for water to accelerate through a downspout, the Deviator redirects roof runoff at the gutter level — before vertical descent begins. It operates within the horizontal flow of the gutter, establishing a defined redirection point earlier in the system.
Nothing is pressurized. Nothing is forced. The control point moves upstream.
Why Gutter-Level Redirection Changes the System
When redirection occurs at the gutter, coordination happens before water accelerates through vertical conveyance. This upstream placement expands how storage can be integrated and how runoff can be coordinated across the property. Planning begins at the collection phase — not the discharge phase.
The design question shifts from:
“Where is the downspout?”
to:
“How does the roof function as a unified surface?”
The Deviator does not increase rainfall. It does not create pressure. It does not override gravity. It simply changes the location of redirection — not the governing laws.
Gravity and Elevation Still Govern
The Deviator does not alter hydraulic reality. Water remains gravity-driven. Elevation determines outcome. Stored water will rise only to the highest available outlet in the system.
If storage is positioned uphill, the Deviator must sit above the maximum water level of that storage. Without elevation advantage, the system equalizes. The laws remain constant. The Deviator operates entirely within them.
Drainage Continuity Is Preserved
Rainfall that is not redirected continues along the gutter and into the downspout, following the home’s original drainage path. The Deviator does not obstruct runoff, trap excess rainfall, or compromise drainage integrity.
Product Water systems are designed with defined continuation paths. Rainfall beyond storage capacity proceeds safely through the existing drainage system. Continuation is structural — not incidental.
What the Deviator Is — and Is Not
- The Deviator is not a rainwater system — it’s a control point within a gravity-based program.
- It does not guarantee tank fill or capture all rainfall.
- It does not replace elevation discipline or coordinated design.
- It redirects a defined portion of roof runoff at gutter level while allowing the remainder to continue its intended path.
System-Level Implications
Because the Deviator operates at the gutter, it broadens system coordination. Redirection begins earlier. Placement flexibility increases. Whole-roof strategy becomes more deliberate. Downspout modification may be reduced, depending on configuration.
The Deviator does not define the system — it strengthens system optionality.
Proprietary Technology
The Deviator is a Product Water proprietary technology — Patent Pending. It is engineered for integration within gravity-based, system-level rainwater programs. Patent status protects the design of the control point. It does not alter hydraulic constraints.
A Shift in Perspective
Rainwater strategy does not begin at the barrel. It begins at the roof. The Deviator moves the redirection point closer to the source, allowing system coordination before vertical discharge occurs.
Gravity governs. Elevation determines outcome. Drainage continuity remains intact. The control point has moved upstream.
About Product Water
Product Water helps homeowners, architects, and municipalities rethink rainwater — starting at the roof. Our systems are built around gravity-based programs, gutter-level control points, and whole-roof coordination so you can Think Outside The Tap.
Whether you are designing a new project or retrofitting an existing structure, we work with you to define clear control points, preserve drainage integrity, and integrate storage where it delivers the most value.
