Flow Gate (Green)

Polylok PDB-4PE-GN Flow Gate (Green)

The Polylok 4 in. Flow Gate is designed to help solve multiple drainage needs. It can be used with 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. When water enters a drain pipe, it needs to go somewhere. The flow gate attaches to either 3" or 4" 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. Note: Fits all 4" pipe and fittings and 3" hubs. If you already have pipe installed, and it's not attached to anything to come up out of the ground, the flow gate can be purchased along with a piece of sewer pipe, shaped like an elbow, to solve that problem. The flow gate can also be purchased along with an elbow, and the Polylok 4" corrugated pipe adapter, to solve that problem. Fade resistant, stainless steel spring, available in green.

• 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 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 
• Stainless steel spring 
• Fade resistant 
• Available with elbow kit & elbow with corrugated pipe adapter kit

The Polylok PDB-4PE-GN Flow Gate in Green is the ultimate solution for all your drainage needs. Specifically designed to be used with 4-inch drain and sewer fittings, this flow gate ensures that water is efficiently diverted and released to safe areas, keeping structures, erosion-prone landscapes, and poor drainage areas protected.

With its innovative design, the flow gate attaches seamlessly to 3" or 4" hub sewer and drain fittings, activating when the pressure of flowing water hits it. This allows for the smooth discharge of water, safeguarding against any potential damage or blockages in your drainage system. Once the flow of water ceases, the gate automatically closes, preventing debris, rodents, or any unwanted elements from entering your pipes.

Ideal for a variety of applications, the Polylok Flow Gate is perfect for use with grates, catch basins, channel drains, flow-wells, downspouts, and roof gutter systems. Its reliable construction features a fade-resistant, stainless steel spring that ensures longevity and durability, even under challenging conditions.

Whether you need to discharge water from retaining walls, street curbs, or any other drainage system, the Polylok Flow Gate guarantees optimal performance. Easy to install and compatible with 4" hub sewer and drain fittings, this flow gate opens with minimal pressure, making it a hassle-free solution for your drainage requirements.

For a comprehensive drainage solution, consider pairing the flow gate with the elbow kit or the elbow with corrugated pipe adapter kit. With the Polylok PDB-4PE-GN Flow Gate, you can trust in a reliable and efficient drainage system that keeps your property safe and secure.
