Professional Leak Detection and Repair Process
When you call for ice maker line service here’s what happens:
- Emergency Shut-off

- Moisture Assessment
Using thermal imaging cameras and moisture meters we check for water that has spread beyond visible areas. Water often travels along floor joists and appears in unexpected places.
- Line Inspection
We examine the entire water line path from the shut-off valve to the refrigerator. This includes checking the solenoid valve inside the fridge and the water filter housing.
- Material Replacement
Based on your home’s needs and local code requirements we replace damaged sections with PEX or braided stainless steel tubing.
- Pressure Testing
Before finishing we pressurize the system and check all connections with a pressure gauge to ensure no new leaks exist.
