What happens if I have a power outage?

The LeakSmart Valve has a dual power source. It is powered with an AC power adaptor and also has a battery backup (4 AA batteries). It is recommended that you keep your valve operating on AC power and only us batteries as a backup power source. If fresh batteries are installed in the LeakSmart Valve, the system will continue to operate in the event of a power outage. It is recommended to have UPS (uninterrupted power supply/battery backup) in place for the LeakSmart Hub 2.0. As long as the hub maintains power, you will be protected. For Hub 3.0 the battery backup is built in and lasts up to 5 hours.
