ABSTRACT:
A cleaning cycle generator for an irrigation system having a programmable irrigation controller. When the irrigation controller terminates an on cycle, the cleaning cycle generator of the present invention will initiate a time delay after which it will turn the sprinklers completely on for a timed period. The sprinklers will then be turned off to complete the remainder of the off cycle. The present invention is particularly advantageous in pressure regulated irrigation valves where particles in the water can become trapped between valve seat surfaces that are in close proximity due to the pressure regulation. Leaking throughout the lengthy off cycle of the irrigation system is prevented by flushing out particles while the valve is in the completely open, unregulated state.
