Sense detected sewer pump running all the time

Device: Pump
Make: Wayne
Model: Sewer Pump
Estimated Savings:

Our sewer pump in the basement only runs when the basement bathroom is being used. We went on vacation and happened to check my sense app and noticed the pump running every few mins. The toilet in the bathroom was running all the time, had a neighbor come over and shut the water off to the toilet. Last time this happened, it had run for a couple weeks and I had a 200 plus water bill.
