Compatibility & Applications
- Intended for use with existing Sloan Top-Mount Optima sensor water closet flushometers.
- Must only be used where the manufacturer specifies this exact part number/model: EBV-129-A-C / 3325450.
Installation & Operation Notes
- Installation should be performed by a qualified plumbing maintenance technician.
- Reference Sloan's G2 Optima Plus Flushometer Repair Parts and Maintenance Guide and the unit's service documentation for correct disassembly/reassembly of the sensor housing and related components.
- Service-document procedure themes include: shutting off water and relieving pressure at the stop/tailpiece connection, removing the cover assembly, disconnecting/reconnecting the battery door clip, mounting the module on the inner cover assembly, and completing reassembly before restoring water.
Maintenance & Troubleshooting
- As the electronic control module for a sensor flushometer, replacement is typically tied to non-functioning or unreliable automatic flush operation that impacts fixture availability.
- Sloan documentation describes G2 Optima Plus operation as battery-powered with an infrared sensor that detects users and initiates a flush cycle after the user leaves sensing range; if the system cannot complete that sequence reliably, the module and its related components are common service checkpoints.
- User feedback frequently associates repeated failures with battery/contact corrosion and moisture intrusion; several reviewers recommend promptly removing included alkaline batteries if stocking the part, and using batteries less prone to leakage for installed units.
