I believe we need a new 50 gallon electric water heater, as it appears we have a small leak in ours in the bottom, causing the cement to be white, which I believe is due to the hard water / metals leaking out and drying.  Our current water heater is about 14 years old, so it is probably time to replace it anyway.  I was hoping you could provide me with the cost to have a new one installed and the old one removed.
