Waukegan, Illinois Patent of the Year – 2024/2025

Lordahl Manufacturing Co. has been awarded the 2024/2025 Patent of the Year for its innovative urinal backup flange. Their invention, detailed in U.S. Patent Application No. 20240384519, titled ‘Urinal backup flange, a repair kit containing the same, and a method for repairing a urinal connection’, introduces a retrofit solution that simplifies the repair of damaged urinal flanges without requiring full pipe replacement.

The patented device features a central flange with a recessed, curved bottom designed to fit snugly over existing plumbing. Flanking this are two lateral “ears” equipped with bolt slots, allowing for secure reattachment of the urinal. Optional tabs with eyelets enable additional anchoring to the wall or the compromised flange, enhancing stability.

This design addresses a common challenge in commercial plumbing: deteriorated or broken urinal flanges that lead to leaks and mounting issues. By providing a straightforward installation method, the backup flange minimizes downtime and avoids the need for extensive plumbing work.

Lordahl’s kit includes the backup flange, a sealing gasket, adhesive tape, and necessary hardware, offering a comprehensive solution for maintenance professionals. The flange itself can be manufactured from durable materials such as brass, stainless steel, or high-strength polymers, ensuring longevity and resistance to corrosion.

This invention exemplifies practical innovation in facility maintenance, offering a cost-effective and efficient method to extend the life of existing plumbing infrastructure. By simplifying repairs, it reduces operational disruptions and maintenance costs for facilities managers and service providers alike.
