Application

Flow control restrictors in roof drains regulate the rate of water drainage, preventing overflow and managing storm water runoff. They help maintain a consistent water flow, which is essential for avoiding excessive ponding on roofs. By controlling drainage rates, flow restrictors minimize the risk of water damage and structural issues, ensuring the roof’s integrity over time.
