I'd highly recommend calling Alberta One Call before doing any digging. Even if you're only going a foot or so underground, its nice to know where they are, ESPECIALLY if you're using ditch witch or other machinery to pull lines.

Never mix and match rotors with pops. They water very differently and require separate watering times to be effective. Putting two separate types of heads on the same zone won't utilize the system. Rotors require 15-20+ minutes whereas pops only need 10-12 mins (depending).

Flower beds you can do with micro irrigation. I'd reccomend runnign a 3/4 pipe behind all your flowers or other trees etc and then plug in micros off that pipe. Or, you can just put heads in the grass and spray the flower garden. You should use a seperate zone for micros/flower beds because they too require a lot less time to water. So if you put it on a grass zone, you'd either over water the flower beds to adequately water the grass, or underwater the grass to adequately water the flowers.

Contrary to some belief, you only need to water with sprinklers about 3 times per week. The frisbee test is a good way to figure it out.

Don't be lazy and do it right the first time. Put the head properly in the ground, straight, not crooked, and for the love of god, put it just a tad lower than level with the grass. You'll bust head after head with your mower if you get lazy.

hmm.. what else

4" pops are what I'm used to. I'm partial to Irritrol, simply because that's all my boss ever used. Although I did service, so I've seen every type of system imaginable.

You can put some 6" or 12" for special areas, usually used in gardens etc.
