Plumbing issues
Here you can see on the left a small drop of water coming out of the joint. I felt above it and it was dry so it is definitely at the joint.

This is from the bottom up. Again you can see the drop at the joint.

This picture is to ask if the knob at the right end is to turn off the water before I try and fix it?

I have no idea what I am doing so I just want to know if I can fix this myself or if I should call the dumb and dumber team to try and fix it? I really don't want them coming in here when I am not home and I know they won't try and arrange a mutual time to come and fix it. Last I knew it was they just show up on Saturday morning to come and fix whatever problem without giving notice first.
