Abstract
A maintenance control apparatus for a lawn watering system includes an accessible electrical receptacle and a portable switching unit. The unit includes a plug for detachably coupling into the receptacle and a selection switch for selectively supplying power through the receptacle to the solenoid water valves. The valves are thereby selectively openable remotely and independently of the clock controller of the watering system. An auxiliary battery and jack are provided to substitute for the main power. A portable master switch electively supplies power to open or close the master valve.
