Polylok 4in Flow Gate (Drainage Pop-Up) – Reliable Flow Control for 4-Inch Drains

Polylok 4in Flow Gate (Drainage Pop-Up) Overview

The Polylok 4in Flow Gate is a compact, durable solution designed to regulate water flow in 4-inch drainage lines. Built for outdoor use in residential and commercial settings, this pop-up gate integrates into a wider Polylok drainage system and offers a practical way to manage runoff with a low profile that blends into the landscape.

What it does

In yards, driveways, or near curbs, a flow gate helps modulate how quickly water moves through a drain. The 4-inch size matches common piping, making it a compatible upgrade or replacement for existing installations.

• Inline flow control for steady drainage of rainwater or irrigation runoff
• Pop-up design that is easy to access for inspection and maintenance
• Durable polymer construction designed to withstand outdoor exposure
• Simple, tool-light installation with standard 4-inch connections

Real-life scenarios

Picture a rainy day when you want to prevent water from pooling along a walkway. The Flow Gate can help reduce surge by slowing the rate at which water enters the curb or trench drain. In a landscaped area, it provides a discreet means to guide water away from foundations while maintaining a clean exterior look.

• Manage driveway runoff and prevent overflows during heavy downpours
• Direct water away from foundations and toward approved drainage paths
• Enable periodic inspection and gentle adjustments without digging up the line

Installation and care

For best results, follow the included installation guidance and align the Flow Gate with your 4-inch drain. Regular checks keep seals tight and ensure the unit remains accessible for maintenance. A quick test after installation can help confirm proper operation.
