Description
This was a (Class 3 | Cat 1) residential water loss. The source of the water loss was a failed supply line associated with the upstairs toilet. The water ran down the north wall soaking the ceiling drywall and the associated R19 insulation in the flooring joists. The Southern California property was built in 1982 and therefore required testing prior to demolition.
Survey Results:
- Down stairs acoustic ceiling - positive 6% chrysotile (serpentine) asbestos (friable)
- Affected north wall - none detected
