FAQ


Q: What types of existing flush valves can this retrofit kit replace?

A: The ZERK-C-ONE-TM is designed to retrofit most standard manual diaphragm flush valves, including both Zurn models and those from other major manufacturers. The kit includes the necessary components to ensure compatibility with most existing valve bodies, making the conversion process straightforward.

Q: How difficult is the installation process?

A: Installation is designed to be quick and straightforward. The process typically involves turning off the water supply, removing the existing valve cap and internal components, installing the new diaphragm and retrofit kit, and restoring water supply. Most installations can be completed in under 30 minutes without specialized tools or plumbing expertise.

Q: What happens if the battery dies or power is lost?

A: The ZERK-C-ONE-TM features a manual override button that allows for manual flushing in case of power loss or during battery replacement. This ensures continuous operation of the restroom facilities even when the automatic sensor function is temporarily unavailable.


Detailed Features & Benefits


Advanced Sensor Technology: The ZERK-C-ONE-TM uses precision infrared sensing technology that accurately detects user presence and departure to trigger automatic flushing. The sensor can be easily calibrated to accommodate various bathroom layouts and lighting conditions, preventing false activations while ensuring reliable operation. This touchless technology eliminates a primary touchpoint in restrooms, reducing the spread of germs and enhancing the overall hygiene of commercial facilities.

Water-Saving Performance: At just 1.1 gallons per flush, this retrofit kit delivers substantial water savings compared to older 1.6 gpf or higher models without compromising flushing performance. The engineered diaphragm and precision ceramic valve work together to create an optimized flush that effectively clears the bowl using less water. For facilities looking to reduce their environmental footprint and utility costs, this retrofit solution offers an immediate path to improved water efficiency without the expense of fixture replacement.

Durable Engineering: Built for the demands of commercial environments, the ZERK-C-ONE-TM features Zurn's chloramine-resistant TPE diaphragm with a clog-resistant bypass that stands up to harsh water conditions and prevents common maintenance issues. The dezincification-resistant brass alloy protects against premature failure in aggressive water conditions, while the gear-driven ceramic cartridge provides smooth, consistent operation with minimal wear. These quality components work together to deliver years of reliable service with reduced maintenance requirements.
