I have a water bill question

[Shane Burke]

I just purchased my first duplex in April.  When doing the inspection on Jan 31 we found the outside water faucet was turned on… just a trickle but definitely running. Ground was soggy and was wet in the basement under the open faucet!   We turned it off and made a note of it in the inspection. I closed on April 4 and everything has been good with the tenant that the open faucet was feet from there front door. They Pd rents on the 1st of every month. Fast forward to now and I received a $725 water bill, from April 4 to June 28. Water/sewer sent water usage and it was 2 to 3,000 gallons used every day for the month of April.   May 2nd the water use dropped to 150 to 200 gallons a day for both units!   The unit with the water faucet outside there door, are in the process of moving out this month.   I have there $575 security deposit.  Last owner didn’t raise rent. I’m working on that. So my question: Would I legally be able to keep the security deposit to help cover the water bill, given that we found the faucet on previously?
