Had a small leak in dining room ceiling. Insurance sent out company to open ceiling and dry out wet material. Found pin hole leak in copper line. The house is about 10 years old. My question is how much of the pipe should be removed or can a coupling just be soldered over pin hole?

You can cut the pipe right at the hole and use a coupling for the repair. Has the water been tested ? It might be a good idea to have it checked. You may need a treatment for the water to prevent future leaks.

Which copper line was it? Hot, cold, or circulation system? Where was it, in the middle of a run or near a tee or elbow?

I would cut out 2 inches on each side of the pin hole for a 4" piece and replace the copper with 2 couplings if you deem it the right thing to do. Then you can cut the piece in different spots to see if the wall thickness is diminished to know if it will be a lasting fix.

The questions that have been asked are very important. You need to find the cause of the pin hole, or you may be chasing leaks all over the house.

Pin hole leaks are caused for a reason I would start with determining if you have corossive water Are you on city treated water or a well. The as a previous post stated check other sections to see if the copper pipe wall has deteriorated Are you recirculating hot water ? You may need to replumb with PEX
