Hi All- I have this inexpensive lav faucet in my rental and notice it leaks underneath where the cold supply is fastened.This only happens when the faucet is on, and it’s coming out of the beveled rubber washer that gets compressed into the porcelain mounting hole on the cold side, under a plastic flange nut. I also think it may leak only when the hot tap is on. Is that washer intended to hold back mixing water or is the mixing chamber inside the faucet faulty? Any suggestions? Thanks!

Try changing the supplies,the rubber is the water seal,there is no mixing unless your talking about turning hot and cold at the same time
Replace the stems or the entire faucet.
The o ring on the stem is most likely worn.
I typically replace the entire stem if it’s plastic.

Check that the aerator is screwed on tight.
Ok tighten the aerator, I'll check that, could that cause the faucet to leak from below? And by stem is everyone talking about the cartridge? I have seen faucet handles like this that leak out the top, but never from below, and only when it's being used. Can anyone explain this? I think I'm missing something. Thanks!
Could the water be going under the faucet when you turn it on and leaking below. Just change the cartridge as
