Black, oily floaters in bathtub
Posted by Dixie on June 20, 19100 at 11:09:56:
We recently purchased a 30-year old home with gas heat and gas water heater. On occasions, apparently when the hot water is turned on full, massive amounts of black, tarry bits appear floating on the water. The black stuff sticks to the sides of the tub and when rubbed, appear to be oily. This happens in both bathtubs, but never, so far, in a sink or the washer.

There is a large, cylindrical filtration unit which appears to be quite old and sits between the furnace and the hot water heater. Would this be the source of the problem? If so, what's the solution? I haven't located any of the "filters" on the market or found anyone that knows what they are.
