First time power outage occurred pumpsitter did not work. Company said it was because I needed an additional outlet for pumpsitter since outlet was overloaded. Put outlet in when had second outage once again, pumpsitter did not work. Said I needed to have had it serviced so battery did not work. Third outage I had one year later the pumpsitter did not work. Company could not understand why it did not work a thrid time. Please feel free to contact me if you have any questions.
