How to stop Water Hammer?

What is Rachio's "Minimize Water Hammer" setting?

With this setting, your Rachio Smart Sprinkler Controller will open the 'next' scheduled zone to run in a watering schedule, 10 seconds prior to the end time of the current zone that is running.

This will help regulate the pressure surge that can be caused when a zone is abruptly shut and subsequently diverted to a different zone. With "Minimize Water Hammer" activated, A smooth transition will now occur, stopping the knocking noise in your pipes and helping the overall system.

To find your water hammer setting, login to your account, select the "More" tab from the navigation bar, select "Controller Settings" and then toggle on this feature.
