Just Algae?? Seriously?! There should not be algae in drinking water. I had
an issue with slow water out of my dispenser and when trying to find the
problem, I turned my water valve open and closed a few times to see if there
was a clog there. After this, I had black water coming out of the line and it
cam thru the refrig and even through the filter. It cleared eventually but is
scary. I called a plumber and he said it is from the old washers. That makes
sense as I turned the valve which would have rubbed the old washers. I'm not
thrilled by this and eventually want to replace the valve and washers, but it
isn't algae.
