This article will show you how to water landscaping or gardens daily, automatically, without making it part of your existing sprinkler system. These instructions were written using the Melnor Electronic Aqua Timer (available at Home Depot) but there are many similar timers available.

[edit] Steps

Find a source of water near your project. Tee of the source and terminate it with a shutoff valve or hose bib
You may already have a terminated water supply or wish to use a standard hose bib.
You may want to set your timer before you install it.
Install a 9 volt battery then set it to "OFF" and press the button. The "Time of Day" light will flash.
Set the correct time and press the button. The start time light will flash.
Set the frequency of watering and press the button. The duration light will flash.
Set the duration time and press the button.
Set the watering start time. The frequency light will flash.
Connect outlet to the watering system. If the system starts with a hose thread connect it and you are finished. If the watering system is pipe or tube you will have to convert the end to a female hose thread connection as shown.

[edit] Tips

Have all your supplies ready before you start.
You can manually water by moving the dial to "ON" to see the coverage of the system.

[edit] Warnings

Let all glued joint cure at least 3 hours before pressurizing.
Be sure to return the dial to the duration time after you have manually watered. You can tell because it will quit blinking when it is on the original time.
