What is a garden irrigation controller?

A garden irrigation controller provides a way of controlling your garden watering without you having to be there to turn the tap on and/or off.


Why might you need a garden irrigation controller?

  • If your garden needs watering at times when you are not there to do it.
  • If you want to control how much water your garden receives (or how much different parts of it receive) and when that water is delivered.

How does a garden irrigation controller work?

The controller inserts a valve between your mains water tap (or source of stored water) and some method for delivering water to your garden such as a sprinkler or garden irrigation system. The valve is controlled by a programmer which opens or closes the valve in accordance with the settings you choose.
