Turning on the spigot valve, I can stand out there and hand water, LOL, but I really want to put the water right at the plant and slowly as I have a loamy clay mixed soil. I also wish to run some fertilizer to each plant.

I think this might be the right order, but not really sure so if anyone thinks it is wrong, please say so!

Spigot
Y splitter
one one side of the Y splitter:
Back flow preventer
pressure reducer,
filter
fertilizer of what ever sort if used goes here
timer with 4 valves for 4 zones
coupling to go from male hose threads to 1/2 inch tubing


Is that right?

Most of the back flow preventers, pressure reducers,
and filters are not meant to be under constant pressure.
So normally you would have your y then your timer.
I have a single timer so it is installed in this order:
Y, timer, BFP, Filter, fertigation (if I had it), pressure reducer, female
hose thread, then your 1/2" supply.. I would check with the
supplier and see if they have a pressure reducer designed to be
under constant pressure. If so then you would have y, pressure
reducer, bfp, filter, fertigation, 4 zone valve, supply lines.
You will like having this once it is set up. I used to spend an hour
every afternoon watering and now this has freed up my time..
I have it set on 6 day cycle and then hand water on Saturdays if
needed, and also add TTF on those days when needed. My timer
also has a button to hold down for 3 seconds to suspend all watering.
I pushed that about 4 days ago due to all the recent rain and once
I am ready to resume just hold down for 3 seconds and it will resume
the program. Good luck.
