Zurn ZERK-SM E-Z Flush® Side-Mount Sensor Retrofit Kit w/ Mechanical Manual Override Button for Water Closet and Urinal Flush Valves

The Zurn ZERK-SM is a sensor-operated flush valve.

The EZ Flush Sensor Retrofit Kit is the easiest touchless upgrade for a handle-operated water closet or urinal flush valve, providing a hygienic user experience. In addition to touchless infrared sensor activation, its true mechanical manual override button delivers on-demand flushing. The sensor unit’s sleek design and reliable, battery-powered gear-driven technology improve the look, lifespan and operation of most existing flush valves. With a quick three-minute installation, the EZ Flush Sensor Retrofit Kit helps reduce material waste by replacing only the handle instead of the entire flush valve, saving materials, costs and time.

Common Questions

How much water does this use per flush?

Zurn's own copy for this exact model does not state a gallons-per-flush figure in the data we hold -- check the linked spec sheet before specifying it against a water-code maximum.

How is the sensor powered?

Battery-powered -- no wiring required.

What rough-in does this need?

11-1/2", per Zurn's own valve-height spec for this model. A retrofit must match the existing rough-in of the fixture being replaced.
