All products must be retested once maintenance has been
performed. Corrosive water conditions and/or unauthorized

internal components helps assure maximum life and proper
product function.

between the upstream shutoff valve and the inlet of the backflow
preventer.

LF909 with Flood Sensor
Series LF909 and 909RPDA each include a flood sensor on the relief
valve to detect water discharge and trigger notification of a potential
flood event.
NOTICE
An add-on connection kit is required to activate the flood sensor.
Without the connection kit, the flood sensor is a passive component that
does not communicate with any other device. (A retrofit sensor connec-
tion kit is also available for existing installations. See "Add-on and Retrofit
Sensor Connection Kits," for ordering details.)
NOTICE
Use of the flood sensor does not replace the need to comply with all
required instructions, codes, and regulations related to installation,
operation, and maintenance of this product, including the need to
provide proper drainage in the event of a discharge.
Watts is not responsible for the failure of alerts due to connectivity or
power issues.
