    😕 When running hot water I sporadically get a stream of total black water. It’s still water but black, black! Any ideas?? Bj

    How old is your water heater? And what is your plumbing made of, copper or steel? Very rusty water can appear black and I’ve seen some pretty nasty stuff coming out of commercial water heaters when we flushed them.

    Also, what make of heater is it? Sometimes aluminum anodes will discolor water.

    Hello: Also, tell us about odor. Is it smelly like rotten eggs, or sort of metallic, or nothing? Do you have an instant hot, or recirc line?

    Yours, Larry

    It’s a Republic ThermoGlas w.h. and I’m guessing about 15-20 yrs old. In 10/1998 the “3/4″ line 5′ section of galv rusted w/hole replaced w/nipple (brass) w/copper up to new flexs.” Hope this helps. There isn’t any odor that we’ve detected. Bj

    The heater may well be rusting if it’s that old, but there could still be galvanized somewhere in your system, as well. Consider checking the anode, but don’t be surprised if there’s nothing left but the plug. Anodes, and water heaters if you don’t change the anode, don’t last forever.
