Irrigation System Shutdown Procedure

Effective closure of an irrigation system prior to winter is key in avoiding freeze damage. The strategy is to shut off the water supply coming into the irrigation pipes through the main water supply. Then, get rid of the remaining pressure by undocking a valve and running the system for a few seconds. Furthermore, it is vital to drain the backflow preventer as trapped water in it can freeze and do damage to this unit. You may need to remove such devices if they are no longer needed in your area. In case of residual water in the pipes, make sure to connect an air compressor in such a way that one zone is cleared first and use the right PSI to blow out the lines. Then, proceed to disconnect the system controller and either set it to ‘off’ or ‘rain mode’ to make sure it won’t be turned on accidentally in winter. Secure the outdoors, as well as the valves by tortuously wrapping the pipes, backflow preventers, or control devices tightly to keep them from freezing. Lastly, double-check that all of the valves are shut, and all the parts are properly secured and dried for the winter.

Irrigation System Shutdown Checklist

Properly guarding irrigation systems against frost during winter is a must in order to avoid any damage from being caused. The procedure starts with turning off the primary water supply to the irrigation pipes so no water enters them. Afterward, open a drain valve or briefly scale the system to eliminate any excess pressure. Don’t forget to drain the backflow preventer too since stuck water may freeze and damage this device; be sure to follow the local instructions, as some backflow devices will need to be removed. Irrespective of any water residues in the pipes, attach an air compressor to each zone, one at a time, using certain specifications for blowing out the lines. Then turn off the system controller or set it to “off” or “rain mode” for the times the controller is disarmed and there is an accidental operation in winter. Insulate any unmet pipes, valves, or backflow preventers by means of insulation that can help in reducing the possibility of freezing. Lastly, make sure that all the openings are shut, the components are secured, and none of them are leaking.

The process of servicing has different steps, such as shutting off the water supply, blowing out the lines to one hundred pounds of compressed air to blow away excessive water, draining the backflow preventer, and insulating the exposed components so that they won’t freeze during the winter. Blowing out the lines with compressed air to drive the water out, draining the backflow preventer, and then insulating the exposed components might be some of the other aspects besides the shut-off. Additional expenses are possible in case of larger or a more complex system, thus it is good to ask for a quote to know the exact price fitting your system.
