black greasy stuff in hot wat
Posted by jens on September 01, 2001 at 11:29:01:

We are having some nasty black greasy stuff coming out of the hot water faucets, when opening the faucets on full. This is so severe that the tub gets a thin layer all around and totally black. When we use real low pressure, we can avoid most of it.

Our waterheater is 10 years old, the house is from 1970, and pipes are probably same age. Waterheater model is a Reliance 501 installed in 1991. Any suggestions to what might be the problem. Our local hardware store suggested grease in the pipe fittings, but there seems to be too much stuff coming out to be from the pipes.

Hope you can help,
