enter image description hereOne of my sink faucets in my bathroom is leaking and I decide to fix it. I can uninstall the handle using allen wrench but then don't know how to find the O-ring or something. I need to know the brand but I couldn't find any logo on it. I need to know the brand no matter whether I will fix it or just go buy a new one (to be the same). Can someone help to identify the brand? enter image description here
just looking at the surface and general look and fit and finish, it looks like a made in china junk faucet. these types of faucets are essentially disposable. even if you can get it apart (which may not be the case), you will never get parts for it.
if you do want to try it, try removing the supply line and nut from the bottom (under the counter) and lift the handle assembly out. there may be a set screw or something under the escutcheon. i have seen enough of these to not offer much hope though. get yourself a moen faucet as a replacement. good pricing, lots of choice, and free parts for life.
The brand name of the faucet is often found facing the wall. Put a hand mirror on the wall and illuminate it with a flashlight.
