@franz - Really impressed with how quickly and completely you responded to my questions. You were much better than the CSR that I first called who I believe was just reading from a script. Makes me feel good about the purchase and the support behind the product.
@Dwiniger - I bought a 3 without the flow sensor as well. Everything is on the opposite side of my house from my controller and I was concerned about the distance as well as the fact that the sensor will require me to call in a plumber or irrigation company to install. I’ll wait and see what other people’s experiences are first.
@Dwiniger The biggest issue with the connectors is not following the directions or recommendations. I have experimented with “Commercial Grade” connectors from my irrigation supply house since I assumed that they would be better than the connectors that they recommend from Home Depot/Lowes/Amazon.
It was more headache than it was worth. Rachio must have done their homework before printing out their final answer on the connectors. I take my hat off to them for going through the engineering steps to be able to properly recommend what actually works.
