Color
Brown or red hot water often means internal corrosion or a depleted anode. Black specks can be anode or dip-tube debris. Do not drink discolored hot water; use cold and have the tank inspected.
Odor
A sulfur smell that appears after the tank sat unused (vacation, vacant house) is a known pattern. Anode swaps and disinfection are technician work. A leaking rusty tank is a replacement, not an odor gadget.
Safety
Odor of gas is not “smelly water.” Leave and call the utility. Electrical burning smell is an emergency shutdown.
