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. I do have pictures but do not see a way of adding them. Any help would be appreciated.

It has water seepage at the threaded connections. Remove the fittings and reseal or you might try and to tighten them more.

The corrosion is not just on the threads there is also a large spot corroding on the outside of the shark bite connection could this also be caused by just leakage? There is no evidence of any water or drips either.

take it off and replace it.. 5 minute job..
