Cold water is soft but hot water is hard?
We have well water and do have a water softener. Recently we had to have a new water heater installed but now we have soft cold water and our hot water has that rotten egg smell while the cold water does not. I had filled up the softener with salt right after the new water heater was installed so I figured that the problem would go away in time once the tank emptied and refilled a few times but the problem still exists after two months. Any suggestions would be appreciated. Thank you.
