I have a problem in two of my bathroom sinks - if water splashes on the faucet, it drips back under the counter - along the cold water supply hose.
I tried putting water at the base of the faucet, that does not leak down.
As best as I can tell, if water splashes around the handle, it gets inside the faucet, and then down the counter and slides down the cold water supply tubing.
I am wondering if I should purchase a faucet kit, open the thing up and see if I can figure it out - but if anyone has tips, please post here! The faucet is a single handle Kohler faucet.
