So I bought a repair kit for my Delta ball-type kitchen faucet. After
replacing the O-rings, I sprayed some silicon lubricant on a rag and applied
some to the O-rings. I also decided to do this to both of the new valve
seats (sprayed lubricant on the rag and applied to them), thinking that they
were rubber and were going to have wear from the ball and handle. Then it
dawned on me that the drinking water was coming through there, what an
idiot!! I removed the valve seats and springs and ran them under hot water
and paper towel dried them, also applying a paper towel into the openings in
the faucet to grab anything else up. After re-assembling the faucet, I ran
the hot water and then the cold water for a few minutes to try and clear
Now I know that silicone lubricant is not water soluble, so rinsing off may
not have removed it all. The drinking water that comes from this faucet
does go through a Brita filter first before consumption. Anything really to
be worried about?
I can't tell you how good or bad it may be to drink the silicone lube,
but I do suggest not using lubes or other materials anywhere in the water
system unless it is specifically recommended by the manufacturer of the
hardware. Funny things happen when mixing materials and usually they are
not good. What might seem like a good idea (If it moves lube it) may not be
if the lube reacts with the specific type of material in the parts, like
washers, which may be made out of many different kinds of materials.
use food grade silicone spray next time for your add on lube but only
for now why not just flush it out with aerator removed and 10 minutes
of hot and 10 minutes of cold. wash out aerator parts, reinstall.
Thanks. I ran out and purchased a new set of springs and valve sets. So I
will remove the other ones and clean out the inside of the faucet with a
rag, and do what you suggest with cleaning the aerator as well.
I believe that most of these lubricants are siloxanes. Many of the
siloxanes are FDA blessed for use in in vivo medical devices. I
wouldn't loose sleep over it, but would recommend not doing it again
without knowing exactly what the composition of the lubricant is.
