I am installing a sprinkler system in my yard in Colorado. I am about
ready to tie it into the main line under the house and run it out the
front and back of the house. Is there anything special I should do
when going through the wall?? I'm thinking:

Dig down in the dirt 1 foot outside where I want it to come through.
Drill a hole through the brick, feed copper pipe out. Fill area around
pipe with silicone. Burry pipe.

It will definately freeze in colorado in the winter, so I'm planning on
having a shuttoff valve under the house and will drain it in the
winter.

Thanks

Denver area here.

Go to Home Depot or Lowes. They have the necessary anti-siphon valves.
If using copper underground be sure to use the proper type for
underground use. Flare fittings without solder connections.

I recommend 1 inch PVC for the runs to the valve manifolds. Also
include a drain valve at each manifold.

My turn off valve is about 5 feet underground connected directly to the
main water line. I didn't put it in and still wonder why they did not
put the valve in the basement. Sometimes those valves get hard to turn
on and off. They have to be turned on full or the drain valve will weep.

The main turn off valve must be a gate or ball type so as not to lose
pressure. They are also available in the sprinkler department of the
stores.

Vacuum breaker such as this is required:

I have two underground boxes for my valve manifolds. One in front and
one in the backyard. Boxes of that type are available at Lowes and Home
Depot. Don't bury the valves as they do need maintenance now and then.
