FAQ

Q: Does the ZER6003AV-WS1-HYD-MB require batteries or hardwired electrical connections?

A: No. The ZER6003AV-WS1-HYD-MB uses HydroX® Power technology, which harvests energy from the water supply itself, eliminating the need for batteries or hardwired electrical connections.

Q: What is the operating pressure range for this flush valve?

A: The valve operates between 25 psi (running) and 80 psi (static). Higher running pressure may be required for certain fixtures — consult the fixture manufacturer for details.

Q: Can the valve be activated manually if the sensor is not triggered?

A: Yes. A true mechanical override button is included on the ZER6003AV-WS1-HYD-MB, allowing on-demand manual flushing independent of the sensor.

NOTICE: Do not use with water that is unsafe or of unknown quality without adequate disinfection either before or after the system.
