The answer to 'my supply line is leaking' is that a leaking supply line is a common plumbing issue that can be caused by several factors, including worn washers, cracked fittings, or high water pressure. The symptoms of a leaking supply line may include water dripping from the connection, visible moisture around the pipe, or water damage to the surrounding area.
To address a leaking supply line, you can try tightening the fittings or replacing the washers. However, if the problem persists or the leak is more severe, it's best to call a professional plumber. They can diagnose the issue, identify the root cause, and provide a more permanent solution, such as replacing the entire supply line or addressing any underlying problems in the plumbing system.
