I'm trying to stop a water leak from the shower handle. I have removed the escutcheon in an attempt to tighten the packing nut, but the nut is inside the wall and I can't reach it with a wrench. I went into the basement to see if I could reach it from there but the brass is flush against the wall also. Is there anything I can do to get at the packing nut without removing unit from the basement side?

Is there anything I can do to get at the packing nut without removing unit from the basement side? Lucky you! Go into a Plumbing Supply House and ask for faucet wrenchesThis is what we use out on the job, (see image) You might want to take this picture in with you. Good luck, Tom
