With the wireless flow meter designed with slip to accept slip fitting it greatly inhibits some installation options IMO. A flow meter with threaded ends would greatly eliminate some install issues becasue Rachio recommends not glueing anything onto unit.
Example, I want to use PVC 1" unions with I can get in threaded and slip to fit, IF flow meter had threaded ends then I could simply buy 1" threaded unions and be on my way. This would also make it a lot easier to fit in place without having to move pipe into push fittings. My install is underground. I need flow unit to drop in place without moving pipes around. I would assume most underground instals need the unit to just drop in as the ability to push or pull buried pipe is most likely not an option.
