Expensive water bill

[Gary Thao]

My water bill this month was 3x the cost of what it usually is. I thought there was a leak somewhere. I found a hose running to a tenants unit upon further investigation. I also saw a small AC unit which I believe the hose is connected to ( No AC in these units). I am responsible for payment of the water per the lease agreement. What can be done to stop this without getting into legal issues.
