Delta Shower Assembly

I’ve installed a new tub/shower. Ran 1/2” PEX to the valve, 1/2” pew to the shower head, and sweat 1/2” cooper to the tub spout. When the tub spout is on everything works fine but when you pull the lever to turn the shower head on the joints on either side of the tub spout elbow start leaking! How do I fix this?

Bad solder joint. Redo it or call someone you can solder.

Tub flow=no back pressure. Shower(diverted) flow=back pressure. The back pressure revealed your bad solder joints.
