mikendar Report post Posted September 29, 2016 I have what appears to be charcoal residue coming through the kitchen faucet. It does it both when using city water or tank water. I have drained and flushed both the fresh tank and water heater. I have replaced the in line filter that I use on all incoming water. Not sure what to try next. Has anyone out there experienced a similar problem? Share this post Link to post Share on other sites
dickandlois Report post Posted September 29, 2016 Take a look under the kitchen sink - clear in the back. Look for an inline water filter. They are common and are also Charcoal based filter. Rich. Share this post Link to post Share on other sites
jleamont Report post Posted September 29, 2016 Mike, just as Rich said, not uncommon for them to be hidden under the counter. Might not be a bad idea to trace the cold water line. Sounds like you have a hidden filter tucked away. Keep in mind it might not be in a place that makes sense for access so keep an open mind while hunting.

obedb Report post Posted September 29, 2016 Could it be build up from new filters finally showing up in your system? A guess. Don't use them. Share this post Link to post Share on other sites
kaypsmith Report post Posted September 29, 2016 Is the residue only in the kitchen sink? If no other place, is indication that would almost have to be as Rich described. Share this post Link to post Share on other sites
