Roof drains backing up in the rain
- Problem
- A call came in at night, in the rain: water was ponding against a parapet wall because the scupper drains were clogged.
- What we did
- The technician cleared the scuppers and collector boxes with a drain-cleaning machine while it was still raining.
- Result
- Water ran off the roof again and the area around the drains was left dry.
