Installing a Zurn ZERK-CPM E-Z Flush Retrofit Kit 

Hi Erik - In some cases, the range is probably set too far out. The facility manager or installer could adjust the range down (adjustment screw underneath the cover) and it will probably fix it. The sensor is likely picking up the door, and as it moves it activates the valve.

Figured it out

Thank you for your comment! Our product manager says: "Battery life is estimated at 3 years with 4,000 flushes per month."

Thank you for your inquiry, are you referring to our Service Sinks with integral flushing rim?

Yes I do.

Our Product Manager says you can use Zurn's EZ Flush Retrofit Kit with washout sinks. Feel free to contact Zurn Customer Care, with further questions.

We're seeing a lot of businesses switching from manual to touchless. In case you're interested we have a variety of sensor flush valves you can find here: www.zurn.com/touchless-solutions
