The 3 replies so far are all ignoring a key line in the OP's text, "I
using a different faucet, which doesn't seem to do the snow globe
it were the water, it should be common to all taps. To my thinking,
difference between the tap the OP is using that is providing the
the other taps is the hose connecting his sprayer to his kitchen
Perhaps the texture of the inside of the hose provides a much greater
area that facilitates crystallization of the hard water compounds in
and now some of that crud is being mechanically washed off the inside
the hose into the water stream.
CY: The hose is only a couple years old -- as I wrote. The soft copper
in the floor is gosh knows how old.
The OP should add a few tablespoons of household white vinegar to a
with the precipitate. If it is a carbonate salt, the increased
acidity from the
vinegar should dissolve at least some of the precipitate.
CY: Good test for carbonates.
However, part of the
OP's text is puzzling. He says that the precipitate becomes evident
water warms up. He should be observing the opposite. Calcium and
salts are more soluble in warm water and less soluble in colder water.
precipitate should be most evident when the ice first melts, and less
the water warms up and some or all of the precipitate dissolves.
CY: The way the OP figures, the solids ppt out when frozen, and are
visible when the frozen ppt thaws, and becomes clear.
This makes me wonder if perhaps the stuff is not a chemical
rather microbial crud. Another test would be to let a different pop
the precipitate (one that has not had vinegar added) sit for a few
days at room
temperature. If the precipitate substantially increases in quantity,
question whether or not he is looking at bacterial or mold colonies
multiplying. If so, once again, the seed crud is probably living on
surface of the hose.
CY: Worth checking. I'll have the OP check that question, and let you
know what he finds.
The solution to the problem might be to figure out if the crud is
microbial. Then disconnect the hose and give it a good soaking and
buy a replacement). If the crud is chemical, use undiluted vinegar.
If it is
microbial, use some clorox, 1/2 cup to a gallon of water.
CY: I've been wondering if I ought rig some way to pump some clorox or
vinegar or both into the cold water line. Not sure how I'd do that,
but something will come to mind. I mean, uh, if the OP should do that.
