Zurn ZERK-C-ONE-TM-S Top Mount Exposed Sensor Flush Valve Retrofit Kit for WC W/ Gear-driven Ceramic Cart, Battery, AquaVantage® Diaphragm

The Zurn ZERK-C-ONE-TM-S is a sensor-operated diaphragm-type flush valve for a water closet. It delivers 1.1 gallons per flush. It features a aquaflush filtered diaphragm seat.

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.

How is the sensor powered?

Battery-powered -- no wiring required.

What fixture is this for?

A water closet, per Zurn's own product name for this model -- confirm before ordering, since the wrong fixture type is a return, not a preference.
