Trying to improve the odor of our well water, I’ve installed a whole house filter and a UV sterilizer (adding it to an existing water softener). Now, the cold water (still with a lot of iron) smells OK, but the hot water actually stinks a bit worse.
I want to shock my water system with bleach, following instructions I’ve found here, and I’m told I should drain sediment out of the hot water heater first. So, I did, and the 1st five seconds’ flow was an opaque brown. But then the water suddenly turned quite clear, and stayed that way for a couple of minutes. I closed the drain, and a few minutes later, reopened it: the water quickly turned a light cloudy brown, and an hour later (after several opening and closing of the drain) the water remains cloudy. (The hot water from the taps is clear.)
So, what should I do? Keep draining until it runs clear again? Leave it for a day, and try again?
