In July, we replaced our 16yr old hot water heater with a Bradford White hot water heater. I know regulations have changed, and this was maybe one of the first models, so we tried to give the benefit of the doubt when it started leaking 4 months later. So, we called the installer, who promptly replaced it with another Bradford White Defender hot water heater. It has been 3 days, count them, 3 days, and it is leaking already. What is wrong with this product???
