I have observed a blue tint in the ice cubes and occassionally from the
water that is dispensed from my sub-zero refrigerator. I already use a
Franke triflow filter system. Any advice on how to eliminate the blue
tint is greatly appreciated. Thanks.
New units use a disinfectant in the lines that is blue that has to be
flushed out before you start using the ice cubes, etc. It could be something
inside the plumbing lines, particularly if they are pex or equal. Never seen
copper do that. Otherwise, can't help.
Good point, but there isn't anything in the tanks that's terribly
dangerous. I'd shut the toilets off, flush them, and then try to clear
the ice maker to check your guess. Blue stuff shouldn't be in the toilets
anyway. It does nothing other than make a mess.
