Rachio Developers -
I’m a big fan of the Water Hammer setting for my setup, but I think it could be enhanced a bit to make it better.
I believe the Water Hammer setting could be enhanced a bit for those with a Well Pump or Master Valve to reduce wear and tear on the pipes and valves. The first Zone Valve should open 1 second (or maybe a user defined value) prior to the Master Valve (Well Pump) being engaged.
Then when used with the Water Hammer setting, the Master Valve would stay on (vs. turning off) for the next zone.
Upon completion of watering all zones, the Master Valve should be turned off first to reduce the pressure in the pipes then close the last zone valve after 1 second (or another user defined value).
Just a thought.
