I live in a town home. My neighbor across the way had plumbing problems and shut off the water butr when he turned it back on there was airbuild up in my water pipes and i notriced it when i used the restroom. Yesterday I went to get dressed and found out there was a leak in my small closet at the sprinkler head above my closet.
The fitting you have purchased is a common compresion fitting. There should be a brass ferrule under each nut. The nut goes on the copper with the threads going to the compression fitting, then the ferrule goes on ther copper. Push the copper untill it stops into the compression fitting and push the nut and ferrule down to the male threads. Tighten the nut till it is good and snug. The ferrule will compress between the nut and the compression fitting creating a water tight seal and holding the copper tight.
