I have had this tankless water heater for about two years, all of a sudden there is little black specs that are coming out of my hot water only. What is this? What do I need to do?

Hi Lexiconnier17,

Couple of questions:
What material is your house plumbing ?
Also, when was the last time you had your heater flushing done ?

Back to you
