TL;DR
A Class 3 water loss is the IICRC S500 category with the greatest evaporation load, where water has come from overhead and saturated ceilings, insulation, walls, carpet, and subfloor throughout the space. A burst pipe in an attic or an upstairs bathroom flooding the floor below is the classic scenario.
What it means
A Class 3 water loss is the IICRC S500 category with the greatest evaporation load, where water has come from overhead and saturated ceilings, insulation, walls, carpet, and subfloor throughout the space. A burst pipe in an attic or an upstairs bathroom flooding the floor below is the classic scenario. Drying demands maximum dehumidification, often wall cavity injection or controlled removal of materials, and the restoration estimate will show far more equipment-days than lower classes.
