To protect your investment during our harsh winter months, it is absolutely critical that your system be winterized. During this service, our trained technicians turn off the water supply to your irrigation system and purge your system removing all water left in your pipes. This helps protect your heads, valves and piping from serious damage due to freezing. Like all other services, we stand behind our work. As long as your water (to the irrigation system) remains off until Spring Activation, we guarantee your system from any freeze damage provided Automatice Rain, Inc. does the Spring start-up also.
