When the temperature is below zero in northern winter, the residual water in the pipes will freeze and expand, which may cause the joints to crack. This article summarizes five actionable winterization tips.
1. Evacuation supervisor
After shutting down, open the drain valve at the lowest point, let the water in the main pipe flow out naturally, and then purge it with compressed air for 30 seconds.
2. Removing and cleaning the nozzle
Remove the nozzle and soak it in clean water to prevent residual water from freezing in the nozzle.
