One possible solution is that the expansion tank is installed on the hot water outlet line. It should be on the cold inlet side because the hot water over time breaks down the bladder within the tank. As the bladder "dissolves" it leaves black specks in the hot water which clings to bathroom/kitchen tubs, sinks, etc. that smear like eyeliner or grease.
The black specks that are floating in your water could be due to the fact that whatever the water is in wasn't cleaned good enough. It could also mean that something fell into the water.

Another possibility is to check the hot water lines connecting your pipes to the hot water heater. The inner liner of reinforced flexible rubber supply lines will deteriorate over time. As the inner liner degrades it leaves small graphite like black flakes that will come out through fixtures as hot water is run.
Could the specks be aspergillus????
Those specks are flea eggs.
lzlala
Chipping of the paint???^~^
mites
chances are you will get a black horse with white small white specks.
i think its because when you turn on the hot water tap the dirt in the tap has gone because the dirt loses the stickiness and hot water gets rids of stickiness
my blackmoor fish started off with gold specks then eventually turned completely gold, as did my baby one, even though the others in the tank didnt, apparently it can be down to water temp or just genes, but they are fine, hope this helps
If the water is hot, the answer is a burned up black dude
you give it a rub under hot water
