Common Symptoms
- Bubbles or foam developing on a coated connection, joint, or valve can indicate a leak location.
Check Before Replacing
- Turn off or disconnect system power as directed on the product label before testing.
- Coat the suspected surface with a flat liquid film free of foam; most leaks form bubbles immediately.
- For suspected microleaks, wait 5–30 minutes for white foam cocoons or tiny bubble clusters to develop.
- After returning the unit to operation, check for vibration-related leaks as directed on the label.
Pro Tip
Focus testing on threaded connections, joints, and valves.
