I have a shower faucet that is spraying out the back of the middle connection (that one that goes up to the shower-head):
I'd like to remove the grey connection (the swivel elbow) so I can see what the washer inside looks like and replace it if needed but the grey end is more than finger tight, I mean I can't loosen it with my fingers alone.
It only has 3 "wings" and it's plastic and I don't want to break it.
I bought a little (6") adjustable wrench but it doesn't feel I'm getting a good grip on it.
Is there a tool that's mean to be used with this swivel elbow end? Seems like this would be easier with the proper tool.
For context, this is in a 1997 Schult mobile home.
The leak drilled a hole in the drywall behind it:
