## Description

The Zurn top mount sensor flush valve with gear-driven operation provides long-lasting reliability with its updated design. It uses EZ Gear technology, which means a gear-driven ceramic cartridge acts as a pilot valve to operate the filtered diaphragm, making it a highly durable flush valve, which can help lower maintenance costs. It also includes a mechanical override button for on-demand flushing. Don't worry if the power goes out - this flush valve is battery operated with the option for hardwiring with battery backup, which provides uninterrupted flushing, preventing standing water. These features, along with motion sensor activation provide a more hygienic restroom experience.

• Made to upgrade manual flush valve to touchless sensor
• Design withstands over 500,000 cycles
• 1.28 gaff flush improves water flow
