For me to get enough play I had to find where the copper was joined with the 1’ sprinkler black PE tubing main feed to the valve box, and create some room in the ground. I will at some point replace the bottom 3/4 Copper and make it all 1’ after the Flow valve otherwise I have 3/4 Copper from Back Flow - 1’ Copper - Flow Valve - 1’ Copper - 3/4 Copper - 1’ PE then to valve box, so makes it a little neater so I can remove the 1’ - 3/4’reducer. I am actually amazed, but not surprised after reading all the Flow Installation posts how many residential setups are so different… all for a standard I suppose.
Curios, have Rachio started mass distribution yet of the Flow Meter?
