I have a water heater that was just replaced the old water heater ended up leaking at the bottom. A new whirlpool electric water heater was installed. The new water heater came with per-installed dialectic nipples. The copper water lines were cut and a shark bite connection was screwed onto the dialectic using pipe dope and the pipe was pressed into the shark bite connection. It has only been two months and there is corrosion evident right at the connection of the shark bite connector to the dialectic nipple. There is more corrosion on the hot water side then on the cold. There is no evidence of any leaks and the previous water heater did not use a dialectic union. What would be causing this corrosion so fast? The house does have a water softener as well. Any help would be appreciated.
