My landlord used my utilities to fill the new electric water heater.?
Please elaborate on how he used your utilities to fill the new electric hot water heater. Did he connect the new heater for an entire building of apartments to your water line? A one time fill of a water heater would hardly register on a water bill. Something else is causing your bill to rise, most likely is a mistake in reading your water meter by the utilityit has happened to me in the past.
