Let them look at it. Can you see inside the tubes clearly? I wonder if they could knock out part of the weld and put in something to redirect the water?
Kim - maybe. I tried to take pictures inside the wrong one and one of the right ones.
Wrong - welding on left. Opening for water on right.

Right - welding on top. Opening on the bottom.

The opening is less noticeable in the correct one because there is a small amount of water pooling.
Maybe there is a way to weld shut the side opening and open the bottom in the wrong one. But it will be a tricky bit of welding either swimming or hanging over the edge.
Maybe they can just carve around the back. Free and rotate the tube then re-seal? Would cost us a piece of slate but we have 6 unused pieces in the garage. It would stink of they have to take off the top coping stone.
A few in progress pics to illustrate the construction.

(Is the one on the left wrong already?!)


I am certainly going to be asking them to come out and take a look/ brainstorm solutions.
