Absolutely not! Do not do that. Have her clear the balance then you can move it to your name. If you have the bill in your name when your leaving make sure peco turns that shit off before you move. If they are not allowed access to the meter (let's say it's in a basement you can't get to - or a closet) it can take 3 attempts before they take you off the bill due to lack of access. Keep every text/email to your landlord when discussing that bill. And never go on the water bill that's the property owners responsibility.
