What’s this Thing on my Valve?
If you just purchased a new backflow preventer, you’re probably wondering about the sensor attached at the relief valve. DON’T REMOVE IT! This small piece of advanced technology, when connected, will provide you with advance warnings of potential problems like excessive water discharge and flood conditions.
The sensor remains off and does not transmit data until activated and connected via an add-on Connection Kit (sold separately). The addition of the sensor to your valve does not change its certification, function, or specification.
Reliable Alerts, Your Way.
Choose the Connection Kit that’s right for you. With the option to integrate via BMS or interact with your system in the Syncta mobile app, alerts you can count on are just a few easy steps away.

Why Connect?
Talk to any facility manager and they’ll tell you that avoiding water damage is a top priority. With smart and connected flood detection enabled on your backflow preventer, you can catch water discharge when it’s a drip, not a deluge.
Monitor Backflow Preventer 24/7
Receive real-time alerts when RPZ discharge is
detected
Reduce Water Waste
Discharge can flow at 500/gpm and go unnoticed
for days
Prevent Costly Property Damage
Flooding can lead to millions of dollars in repairs,
downtime, and revenue loss
Add Flood Detection to Any Install
Ready to connect? Your new valve arrives with a connection-capable sensor. This sensor is turned on with the purchase of an add-on Connection Kit. Once you’ve purchased, installed, and activated your Connection Kit, you’ll receive real-time alerts that keep you ahead of flooding and water damage. Have an older-model valve? Make it smart with a Connected Retrofit Kit.
How it Works
Install your backflow preventer as usual and find your Connection Kit
Purchase and install your Connection Kit to activate flood sensor
technology
Enjoy reliable flood monitoring and alerts via your BMS or Syncta, our mobile app
