We're having an external tap put into a garden to make watering easier. I'm hoping this also means we're able to buy a timer to automatically water the garden whilst we are away. I just wanted to know how water timers work and if you have any recommendations?
Is it simply a case of fitting the timer and turning the tap on? How is the flow restricted when the timer is set to not dispense water? Do I need to have a particular type of garden tap for this to work?
