Storm drain flap – protection against flooding and rodents

This storm drain flap, made of high-quality polypropylene, is a reliable solution for protecting drainage systems for rainwater or wastewater. It is ideal for use at the end of drainage or corrugated pipes with a diameter of 72 to 100 mm, mounted on end pipes draining water into drainage ditches. Its construction provides effective protection against flooding of rooms and the entry of rodents into the building.

Durability and resistance to external factors

The flap is made of polypropylene with the addition of a UV stabilizer, which guarantees its resistance to sunlight and other weather conditions. This material is also harmless to the natural environment and withstands temperatures up to 95°C, and is also resistant to aggressive chemicals, such as plant protection products. All metal elements are made of stainless steel, which further increases its lifespan.

• Durable polypropylene: ensures long-term use even in difficult conditions.
• Thermal resistance: safe operation at temperatures up to 95°C – ideal for wastewater drainage.
• UV stabilization: protects against the negative effects of sunlight and premature aging of the material.
• Universal connection: compatible with popular Karmat drainage fittings, making it easy to install on different types of pipes.
• Rodent protection: the chrome-nickel plated flap cover protects not only the flap itself, but also the seal, preventing it from sliding off and allowing rodents access to the inside of the installation. An additional lever cover made of chrome-nickel steel increases safety.

Thanks to these features, this flap is a solid investment in the safety and durability of the drainage system. It is a solution appreciated by both professional installers and end customers looking for a reliable product.
