FLOW GATE
3”/4” FLOW GATE
The Polylok 3”/4” Flow Gate is designed to help solve multiple drainage needs. It can be used with 3”
and 4” drain and sewer fittings. It allows water to be diverted and released to water-safe areas away
from structures, erosion-prone landscapes, and poor drainage areas.
FEATURES
• Allows water captured by grates, catch basins,
channel drains, flow-well, downspouts and roof
gutter systems to flow through the drainage pipe
and to a water safe area such as a gutter
• Opened by the hydrostatic pressure of water
flowing through the drain pipe, as flow diminishes
the emitter closes again
• Great for discharging water from retaining walls
and street curbs
• Fits 3” and 4” hub sewer and drain fittings
• Flow Gate opens with minimal pressure
• Closed during dry weather to help keep debris
and rodents from entering the drain pipes
