Impure or ‘hard water’, rust particles, improper installation, etc all can cause copper unions to leak. To stop leaking, you can reseal the unions with a wrench. Plumbers use copper union joints in steel pipelines for many reasons. Copper union joints enable the pipes to be removed when they get damaged or corroded. 13 Jan 2014. #6.

You will need to use specific clamps (ones used to secure pipe to fittings) and a tool that squeezes the clamp around the pipe securely. It is good practice to double up on the clamp on each joint for Clogs or joint breaks ; While not immediate emergencies like gushing leaks, you cannot ignore moderate leaks in a pipe. Fixing a moderate leak can require stronger holds than pinhole leaks, typically sealing putty, thread seals (for thread or joint leaks), patches and clamps, and higher-strength sealing tape. The leak was coming from the threaded joint at the shower arm and the drop ear elbow: Shower Leak behind the Wall Repair: Shower Arm and Elbow Joint Leaking. I unscrewed the shower arm from the elbow and observed that: The shower arm was threaded-in very tightly – this is good. The threads were sealed with pipe joint compound – also good.
