Water timer

A water timer is a electromechanical device that, when placed on a water line, increases or decreases the water flow trough the use of an embedded (solenoid) valve. It is used in conjunction with sprinklers to form a automated or non-automated sprinkler system, capable of administring precise amounts of water, at a regular basis.

Alternatives to water timers

An alternative to a water timer to administer precise amounts of water at a regular basis, is to precisely calculate the needed waterflow and arrange a system composed by a Time switch and an electric pump that. The electric pump is to be arranged to be turned on and off at regular intervals by the time switch to administer (fairly) precise and regular water quantities. [ [http://berserk.org/ois/ Time switch with electric pump and flow calculation replacing water timer] ] This approach, used frequently in DIY watering systems, allows financial savings as the water timer can be discarded. For high-end applications however, water timers sometimes allow more flexibility and more options.
