In order to properly winterize the system you need to blow out all the lines with an air compressor.
on all of my company's systems within the last 6 years or so have hose bibbs installed next to the shut off valve to hook up an air compressor to main line. and we :
1. turn off the shut off valve
2. turn on hose bibb
3. turn on air compressor.
4. go through each one of your zones from the timer or vavles and blow out until just air comes out of the heads.
5. turn the hose bibb off.
6. leave the shut off valve off..
other ways of hooking up an air compressor to a sprinkler system is :
hook up at the bottom of a sprinkler head.
do this on each zone and turn off at the street and go through each zone from the timer the same way.
if you can cut off the heads with a tool, then you wil only have to dig up one of the heads to hook up to.
blow out all the water on the zone that you hooked up to.
then turn off all the other heads on that zone and you will be able to blow out the others.
hope this helps

Yes, once the water is shut off, you need to force all of the water out of the system. Usually this is done by hooking it up to a compressed air tank and blowing the water out.

If you live in an area where this needs to be done, then in addition to turning off the water, you need to make sure that the water in the lines is drained. Depending on your system, you may have an automatic drain valve, or you may have to do it manually. Check with the manufacturer of the system or with a local installer to verify.

Yes, you need to run air through it to blow the water out of the pipes. If the water is left in the pipes and it freezes inside the pipes, then the ice will expand in the pipes and burst the pipe.

Yes You should use an air compressor to blow the water out of the line, The more water you blow out the safer your system shoud be.

Just ensure that once you shut it off, there is no water remaining in the system.

You need to reset the ON/OFF times in the programming.
