|In response to Re: Black, oily floaters in bathtub|
: 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.

The fresh water pipes are a very unlikely manner to get these oily deposits, but what the heck, open the filter cylinder thingie, pull out the filters, and look inside with a flashlight. Any black oily stuff? No? take the filters to the plumbing supply house (Not Home Depot) and ask for replacement filters. Take the name and model number of the filter housing with you.
How about the caulking and walls around the tub. Is there any chance that there's tarpaper behind the wallboard? old tarpaper could be leaving your oily spots . Do the tubs share a same wall? Maybe thats where you need to look, is behing the wallpaper and drywall to see if the tar substance comes from there
