have you got an old metal cold tank feeding your hot water system? these old tanks are prone to rust. it could be yours has reached the terminal stage. have a look. you'll probably be disgusted by what you see anyway - that's why never drink the cold water from the tank!! - or the hot water fed by the cold tank. :shock:
time to replace with a nice plastic one.
