I recently purchased a Bradford-White water heater and had it installed professionally last June. I've been noticing water at the bottom of the water heater near the drain in the floor. At first I thought it was coming from the tube that drains condensation from the furnace since that has happened before. But then I came to my senses and realized the A/C hasn't been on in weeks. Did I just get a defective unit or could something be wrong in the installation? It's a small leak that comes from underneath the tank. Also, how much of a PITA is it going to be to get it replaced and I'm going to have to shell out any more money? I will have to look for the receipt as I'm not sure where it would be. Your help is greatly appreciated.
