Apparatus for connection with a sill cock for communicating water under pressure from the sill cock with a hose having a lawn sprinkler communicating therewith comprising a water control unit having a female coupler for connection with the sill cock, a male coupler for connection with the hose, a valve between the couplers and a battery operated valve mechanism operable in response to the connection of the electric current thereto for effecting movement of the valve from a closed position into an opened position, and a manually portable programming unit containing a battery operated programming keyboard, a battery operated display, and batteries operatively connected therewith. An extension cord accessory is provided which renders the portable unit operable to operate the water control unit either in its operative position or when the portable unit is disposed in a remote position. When the portable unit is provided with a modified keyboard permitting programming of three separate water cycles, the apparatus forms part of a whole lawn watering system which includes a stepping valve unit operable as each watering cycle occurs to connect the outlet of the water control unit to a different sprinkler.
