How a toilet overflowed decides how it is cleaned. Water from a stuck fill valve or a supply failure is clean. Water from a clogged bowl is gray, and water that came up from a backed up drain is sewage. The crew identifies the type first, because it sets the protective gear, the materials that can stay and the cleaning method.
Three kinds of toilet overflow
Each kind of overflow is handled differently from the start:
- Clean supply water: extracted, then dried like any plumbing leak
- Gray bowl water: extracted, sanitized and checked for soaked pad
- Sewage from a backed up drain: contained, removed and treated
- Carpet that sat in gray or sewage water is usually replaced
- Tile, vinyl and sealed floors are scrubbed and sanitized
The city sewer behind the toilet
Household wastewater from an Azusa toilet drains into the local sewer system the City of Azusa maintains, which in turn feeds District No. 22 trunk sewers. A toilet that overflows repeatedly may point to a blockage in the house drain, and a plumber can check that before the floor is dried.
Drying under and below the bathroom
Water that crosses a bathroom floor slips under the toilet flange, along the tub edge and through gaps into the subfloor. Moisture meters check the subfloor and the ceiling below, which may need opening if it reads wet. A two story or stacked building adds a lower unit to check, so ceiling leak water damage and sewage backup cleanup cover the cases where the overflow travels or is contaminated.
