The Polylok 6 in. Flow Gate is designed to help solve multiple drainage needs. It can be used with 6 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. When water enters a drain pipe, it needs to go somewhere. The flow gate attaches to 6″ hub sewer and drain fittings, and pops up when the pressure of the flowing water hits it, allowing the water to discharge. Once the water stops flowing, the flow gate closes again blocking anything from falling in. Just press the flow gate into the pipe, and forget worrying about finding debris, rodents, or anything else you don’t want in your pipes.
- 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 6 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
- Stainless steel spring
- Fade resistant
