Home built in the last few years... I have a copper half inch line coming out to an outside faucet (3/4 faucet). I am not going to attempt to run a new 3/4 copper (in the basement) until the spring, so i am just going to attach the system to the faucet temporarily via a pvc slip to hose thread.
The entire system is based on PVC SCH 40 (3/4 inch), and has 4 zones. I have 80 PSI coming from the faucet and about 12.5GPM. All heads are the same...Orbit Voyager 2 (3/4 connection, 3.7GPM@60PSI 2.6@30PSI)
Zones: 1=4 heads (90ft), 2=3 heads + 1/4 inch drip line (60ft), 3=3 heads + 1/4 inch drip line (130ft), 4=4 heads (80ft).
After blowing out the system for the winter via a 70PSI + 2CFM:

I plan to just take the entire manifold into the garage for the winter.
I also plan on adding an AVB under each valve so to remove any vacuum issues when the valves turn on or off.
The major brass component below the faucet is a double check valve followed by a AVB (this may need to be changed over to a Pressure Vacuum Breaker

When running the new copper, I plan to run 3/4 inch copper with a female fitting and a pvc male with a master shut off valve on the copper.
The entire system is on a slight grade away from the house, and I plan on building a gravel bottom box in the garden down about 12 inches from the surface level with the highest point of all the zones.
Anyone have any suggestions? I'm still learning
