Anyone living in freezing environments should know to blow out their sprinkler system before a cold snap comes through and freezes the water in the line (destroying it). I purchased (but have not installed) the wireless flow meter recently. One of the things that immediately jumped out at me was the exposed PVC (or other material). It occurs to me that the rest of my backflow preventer is insolated and the wireless flow meter is exposed.
Perhaps Rachio should consider producing a shaped foam kit to insolate this device to assist in maintaining temperature during these cold snaps (despite it being advisable to blow out the lines regardless). This would have the added benefit of maintaining the material from UV raditation (it would help prevent bleaching or fragility due to exposure).
Any thoughts?
