Irrigation Clocks
When used correctly, your automatic irrigation clock is the key tool that makes Water Management work for you. An automatic clock takes away the guess work and allows you to do a lot more with your water than simply turn it off and on. It also frees you from the task of hand watering the yard.
Look for an irrigation clock that provides all of these functions:
1. Sets the time of day
This feature presets the time into the clocks memory.2. Sets the day of the week
This feature presets the day of the week into the clocks memory.3. Sets running time for each individual station
This feature allows you to program the running time through each valve. For example; Valve A has 15 minutes running time, Valve B has 8 minutes running time, etc.4. Has dual programmable watering schedules
This feature allows you to set some stations to lawns and some stations to landscape. Also allows you to set a separate day program.5. Sets program times
This feature tells the computer to turn the program on to the preset times. For example; 1:00 am, 3:00 am, 5:00 am. Clocks should have a multiple program schedule.6. Has an automatic/manual switch
This feature allows you to: a) Water the complete program at any given time without losing your previous schedule, and b) turn any given station off or on at any time without interfering with the preset schedule.All irrigation clocks need to be kept in a cool dry place away from the elements. Many people keep their clocks in the garage or somewhere else around the house that is easily accessible. Take the time to inspect your clock and understand its functions. In summary, all your clock basically does is turn your irrigation valves on and off at selected times.
WATER CONSERVATION DEVICES
PCD's
Pressure Compensation Device. A plastic or rubber cone that is attached to the bottom of a nozzle. It has the same function as a WaterSaver. PCD's are inserted into pop-ups and shrub adapters.
WaterSavers
A plastic disk that is inserted into the bottom of a shrub adapter. Its function is to stablilize water pressure, reduce fogging and reduce water runoff. WaterSavers come in green to accommodate 1/4, 1/3, 1/2 spray patterns, and black to accommodate 3/4 and full spray patterns.
Repairing Broken Irrigation

After locating break, dig down with the shovel to the pipe. Then expose 16" of pipe with a 6" clearance all around for easy access. With telescope coupling completely open, measure it next to the broken pipe. Take 2" off that measurement and then cut pipe.
Take sandpaper and smooth down the cut ends. Glue the big end of the telescope coupling to one end of the pipe. Add slip coupling to small end of telescope coupling and glue it to the other PVC pipe. Let dry and replace soil.
