I’m glad the flow meter was brought up. Thanks @Watermiser. I have some questions too. Retrofits with in ground devices will be a challenge.
Here are my questions:
Now the installation specs say the sensor only needs 6" (vs. before which was 18") of pipe after the backflow device. Around here in the south, most new systems are in ground and have a master valve within 6" of the backflow device.
-Can the sensor be installed after a master valve?
-Is there a minimum distance after the sensor to the first turn?
It’s recommended to install the sensor above ground. Around here they would be underground, and more than likely get covered with dirt.
-Have these sensors been tested long enough in the ground while weathering two seasons?
-Does installing them in the ground void the warranty?
What if a zone valve fails to open due to a diaphragm issue or cut common wire.
-Will the sensor send a no-flow notification alert?
