Just moved into a new house and setup my Rachio 3. Couldn’t resist firing up the existing system to figure out how I want to make changes etc.
In hindsite, I may have been a bit premature in my turning it on as I live in Denver and we are due for a May Freeze annually.
My old system was very straightforward and had an inlet for me to hook my air compressor up to for winterization. This may be a beginner question, but take a look at this and let me know how you would blow it out! I have a main shut off valve in the house and I know to turn to 45’s etc.
Note - I realize I would hookup to the upstream valve going into the back flow, but its damn close to the house! I cant get my airline on it. I guess I could get a tight 90 degree.
