You can disable or customise your Sonic's auto-shut off function in your Sonic app. Once you've launched the app, simply go to "Settings" and then under Shut-Off and Notifications" you can enable or disable auto shut-off.

You can also specify the exact parameters for when you want to be alerted of a potential leak: either by volume (i.e. how many litres of water would need to flow for you to be alerted) or time (i.e. for how long water would have to flow for you to be alerted).

Please note that when you disable auto shut-off you will still be notified of the Water Usage Events.
