Pride Plumbing was called out for a water leak on a Zurn wall-hung urinal. When we tested it, we found that it was leaking around the large nut on the vacuum breaker tube. We disassembled the vacuum breaker tube, installed a new vacuum breaker and gasket, reinstalled the tube, tested it, but the leak persisted. So, we replaced the vacuum breaker tube itself and solved the issue. We flushed the urinal several times to ensure that there were no further issues.
