@outbreak @emil thank you so much for the pictures. Showed my dad and this gives some great ideas. One idea I had was to KEEP the index valve but use it just as a collector/manifold (instead of the log style that I linked earlier or that you essentially built). I'm pretty sure I can unscrew the indexing valve and remove the actual valve inside, which means I already have all 6 of my zones merging into 1 central spot.
I used MS Paint (dont laugh lol) to do a real quick mockup on an image from google (not my own). I think I can get those same inline valves and simply saw all 6 lines and just install them in place. Since it would raise my piping, I would need to adjust the other side of the piping accordingly. Any thoughts on this?
Also comparing my set up to my dads (also in Coral Springs), he DOES have a pump where I do not. The best guess we can think of is his water comes from a well whereas I use city water. Perhaps city water already has pressure and therefore doesnt need a pump?
Also there is some sort of solenoid between where the water comes in before the indexing valve. Is this the 'pump relay' or something similar? I am guessing maybe its a valve that is OPEN / CLOSE and what basically turns on my sprinklers since it already gets pressure from the city water. I am completely guessing but that makes sense in my mind lol. With that all in mind, I would just keep this and wire that solenoid into the Rachio I presume, or would I need any extra parts? Again here is the picture of the solenoid/valve thing. You can see it has some wiring coming from my timer and is plumbed inline with the water.
