I've been tolerating a small leak for a while in our bathroom, but it's started to get bad enough that it needs fixing.
While I was hoping I could just pop out the handles and replace an old O-ring or set washer, I can't for the life of me figure out a safe way to remove the handles. The handles are missing the screws, & won't budge with force.
Here's a picture of the faucet type and a detailed pic of the handle:
There is no cold/hot shutoff in the room (I'm guessing it's under the house, not easily accessible), so I'm not really sure which handle I'd need to tighten up/replace parts for yet. I have easy access to shut off the main water supply in the event I need to start cutting things off.
Suggestions on how to proceed?
