Think Outside the Downspout with the Deviator

The Deviator is a specialized gutter insert that turns your gutter into a horizontal rainwater collection rail, so tanks can live where they actually fit—not just under downspouts.

Designed for homeowners and designers on tight urban lots who need storage away from the house without giving up roof capture.

From sky to storage: the Deviator captures roof runoff at the gutter, sends it through a sealed delivery line, and fills a remote horizontal tank from the bottom.

How the Deviator Mounts

The Deviator installs at the low spot in the gutter, just upstream of the downspout. It intercepts roof runoff before it drops vertically, feeding a sealed line that can route water horizontally to storage.

The Deviator captures flow at the low spot in the gutter—just upstream of the downspout—so rainwater enters the sealed delivery line before it ever reaches the vertical pipe.

Bottom‑Fill Storage Away from the House

Instead of dumping water into an open barrel at the top, the Deviator delivers through a sealed line to a bottom connection on the tank. This keeps storage out in the yard while maximizing usable volume and reducing splash or overflow near foundations.

Scaling Up to Large Roofs

On bigger roofs, the Deviator turns long gutter runs into hydraulic collection rails, routing high volumes of water to larger tanks in the landscape without crowding the building. That means less uncontrolled discharge at downspouts and more of your annual rainfall captured where it can actually be used.

“On our 1,200‑square‑foot roof in Ballard, the Deviator system redirects over 10,000 gallons of rainfall between April and October. Instead of dumping that water at the downspouts, we send it to about 1,350 gallons of tanks tucked under the back‑yard decks. Those tanks feed a timer‑controlled irrigation line, so the plants stay watered and our summer needs are covered even when we’re out of town.”

Deviator FAQs

What does the Deviator actually do in my gutter?

The Deviator is a compact insert that sits at the low spot in your gutter, just upstream of the downspout. It intercepts roof runoff and sends it into a sealed delivery line so water can move horizontally to storage instead of falling straight down.

Why is bottom‑fill storage better than a regular rain barrel?

With bottom‑fill, water enters the tank at the base through a sealed connection. This keeps storage away from the house, reduces splash and overflow near foundations, and lets you use more of the tank’s volume than a typical top‑fill barrel.

Do tanks still have to sit under downspouts when I use the Deviator?

No. The whole point of the Deviator is to turn your gutter into a hydraulic collection rail. Once water is in the sealed delivery line, tanks can sit along fences, in side yards, or near gardens—wherever they fit best on the site.

Can the Deviator handle large roofs and bigger tanks?

Yes. On bigger roofs, the Deviator captures flow from long gutter runs and routes it to larger horizontal tanks in the yard. This lets you scale storage without cluttering the building with multiple barrels under every downspout.

Will the Deviator work with my existing gutters and downspouts?

In most cases, yes. The Deviator is designed to retrofit into standard gutters at the low point near a downspout, using a sealed hose or pipe to connect to remote storage. During a site review, we confirm gutter type, low‑spot locations, and routing paths before recommending a layout.
