You can go with the 3/4 copper to the outside because it is a short distance and also a 3/4" backflow device. I would go with 1" valves and manifold and 1" poly to the sprinkler heads. It's not that much more money and the flow characteristics are much better. We, on a regular basis flow 10 GPM on a 3/4" copper service and we always use 1" poly. I'm not familiar with a 32SA head. Must be Home Depot??? Your good on your head count and spacing. Three rows with heads evenly spaced, (9). The nozzle size for the 4 half circle heads should be approx. twice the size as the 4 corner head nozzles. likewise the 1 middle head should have a nozzle that is approx. 2 times the size as the half circle head on that zone.. You should be able to do this safely with 3 zones. Look at the rainbird 5004 series head.

Thanks everyone! I've decided to take the leap... I will purchase 5 gallons of paint tonight and get started on this Saturday. The more I look at that yellowish/tan against the new faux wall I don't like it. It's like being in two different houses lol. I will be sure to post more photos once everything is completed. I actually did a cherry/black colored faux wall and a gray/dark gray faux wall too. The entire house is getting a makeover... all the pictures/fayer table/lamp, etc you see in that photo above is new. I'm trying to get away from the 'basic' house look if that's what you can call it.

We have marble, and I've found the long, metal-rod trivets from Ikea to be invaluable. We keep one sitting next to the stove most of the time, and I find it to be much less intrusive looking than the silver heat pads. Another necessity is a giant cutting board. If you don't want to leave it out all the time, you may not want a really thick one. We have a nice Boos block one that we rarely use because it's so heavy, and I hate pulling it out of the cupboard. Instead, we actually end up using our giant one that was originally an under-counter pullout in our old kitchen. We do a lot of prep on it, and its size makes it useful for keeping potentially acidic juices from running over the edge. Here is a link that might be useful: Ikea trivet

Thanks everyone for the feedback. We are in the mountains at altitude 3500 ft. We will be coming out of our summer/dry season in another month or so, and then starts our winter/rainy season. It’s nothing like monsoon weather but more like Florida rains. Mornings are sunny.. then in the afternoon it rains and then clears up an hour or two later and the sun is back out. It’s not really humid here.. is that something that orchids require? @ Gary.. tell your wife the "creepy crawlies" aren't really that bad. Yes we see bugs, but no more than we saw when we lived in Indiana. The bugs are just different and a bit bigger... but most are outside and if you treat your yard once a month you don't have much of an issue. In the 14 months we've been here, we've encountered one snake, 2 tarantula, 2 giant grasshoppers, a few cockroaches, no scorpions and all have been seen only outside.
