The Polylok 4 in. Flow Gate is designed to help solve multiple drainage needs. It can be used with 3 in. and 4 in. drain and sewer fittings. 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 in. and 4 in. 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
