Replace 9v backup battery. Instructions below. Set for 3 day cycle, with day one on, days two and three off, being sure day one falls on the castle rock schedule for our house, or you’ll get watering citations. Program stations 1-4 (there are only 4 stations) to each run for 15 minutes. Set two times for watering to 7 am and 10pm, unless extremely dry then add a third time for drought t weeks.

In spring, get long keytool and turn on sprinkler system water main in hole in front yard. Test by running on manual, cycle through each station and replace broken sprayers. In fall, turn this off and blow out each station or lines will freeze.
If cannot figure out, call sprinkler guy, Michael Olivas 303-877-0740 but it’s expensive about $100-200 to have him turn on and check for broken ones or blowout in fall.
Time to winterize
All of a sudden, fall is here and that means it is time to prepare the irrigation system and our landscapes for winter. Hopefully, you have already decreased the number of days per week of watering. As temperatures cool, plants don’t need as much water. Given our temps and a bit of moisture, once a week is probably sufficient.
However, by the end of October, we could begin to see freezing overnight temperatures. Therefore, irrigation systems need to be blown out, hoses need to be detached from spigots and mulch should be added to plants.
Blowing out irrigation systems helps prevent breaking of sprinklers and backflow devices. Drain hoses but keep them handy, perhaps hanging in the garage, ready for potential winter watering.
- Turn off (clockwise) the irrigation valve to the house in front yard.
- Attach compressor hose to blow out terminal next to valve.
- Turn on compressor red power switch, with black knobs all the way counterclockwise. Allow tank to fill to 150psi and it automatically shuts off.
- Turn on station one on green control box in garage. Turn black knob rapidly clockwise. Station one will blow out.
- When tank is empty. Turn knob back all the way counterclockwise. Allow tank to fill to 150 psi and repeat on station two.
- When tank is empty. Turn knob back all the way counterclockwise. Allow tank to fill to 150 psi and repeat on station three.
- When tank is empty. Turn knob back all the way counterclockwise. Allow tank to fill to 150 psi and repeat on station four.
