• Common Symptoms: Persistent seepage at a threaded fitting, hard makeup on dry threads, or recurring leaks after older joint compound has dried out.
• Visible/Sensory Cues: Dried paste in the threads, dampness around the connection, joint compound that skins over in storage, or fittings that squeak and bind during assembly.

Pro Tip: Brush the sealant onto clean male threads only and keep the first thread mostly clear so excess compound is less likely to enter the line.
