My shutoff valve for my outside faucets is leaking. I likely need to tighten the packing nut. However, the space I have to work with is really small. I can't get a wrench in here. I don't have a basin wrench but I know this is too small a space for that too.
The nut is really close to a piece of wood which makes it harder to access.
Any ideas on what kind of tool I could use?
This is a small panel in a basement wall.
