ELECTROMECHANICAL APPARATUS, SYSTEM AND METHODS FOR DISPENSING OR PURGING FLUIDS

摘要

An improved electromechanical apparatus for injecting or purging fluids on demand is disclosed. Also disclosed are systems and methods for using the apparatus, including automatic fertilizer injection/injecting and water line purging systems for use in lawn maintenance. The apparatus can be located in a main water line before the distribution valves of an irrigation system, for example, where it can be activated or deactivated without interfering with the normal usage of the system.
