Yes.
Yes. Plenty on this forum.
What I’ve concluded from being on the community forum is that Rachio controllers are being installed on aged irrigation systems. People are installing the controllers, playing with the app controls and turning their systems on manually a lot more. They are becoming more in touch with their irrigation systems components than ever before. This is a good thing.
The only relationship between a Rachio and a diaphragm is the Rachio customer’s interaction with the activation and being there at the same time the incident happened. The same thing would have happened on any other controller.
