Why this kind of loss is common
Garden-style apartment buildings, which Aurora has in large numbers, often stack bathrooms directly above one another. A toilet fill valve that sticks open can run for hours while a tenant is away. Water spreads across the bathroom floor, soaks into the subfloor and follows the plumbing down. The units below see it as a ceiling stain, then a drip, then a steady flow at a light fixture or exhaust fan.
Because the source is a toilet, the water's category matters. A fill valve overflow from the tank is not the same as a bowl overflow with waste, and that distinction shapes what gets removed in each unit.
The situation
Illustrative example. Not a real job or customer.
In a hypothetical three-story building, a third-floor tenant leaves for work. The toilet's fill valve fails and the tank overflows continuously. By early afternoon, the second-floor tenant notices water dripping from a bathroom fan, and soon after the first-floor tenant finds water on the kitchen floor below.
- The second-floor tenant calls the property's maintenance line; maintenance shuts off water to the third-floor toilet using the master key.
- The manager confirms the water came from the tank, not the bowl, and notes that in the job record.
- Each of the three units is photographed and given its own section in the contractor's documentation.
- Water is extracted from vinyl floors and carpet in each unit; ceiling drywall in the second-floor bathroom and first-floor kitchen is opened to drain and dry.
- Drying equipment runs in all three units, with readings logged per unit.
- Each tenant is told to notify their own renter's insurer about belongings.
The third-floor unit dries first; the first-floor kitchen takes longest because water sat in the ceiling cavity. Separate records let the owner's insurer and each tenant's insurer handle their own portion without disputes.
Who handled what in this example
| Unit | Damage | Main decisions |
|---|---|---|
| Third floor | Bathroom floor and subfloor wet | Toilet repair; check subfloor under vinyl |
| Second floor | Bathroom ceiling, fan housing, floor | Open ceiling to drain; replace fan if water entered the motor |
| First floor | Kitchen ceiling, cabinets, floor | Open ceiling; check cabinet bases for swelling |
| Common | None in this case | Hallway checked to confirm |
Decision points
- IfThe water came only from the tankIt was treated as cleaner water, so drywall and cabinets were dried and evaluated rather than removed outright.
- IfThe bowl had overflowed with wastePorous materials it reached would generally have been removed and surfaces disinfected in every unit.
- IfA tenant could not be reached for entryThe manager followed the lease's emergency entry terms and documented it.
Questions each tenant should ask
- Was the water from the tank or the bowl, and how was that confirmed?
- How long will equipment run in my unit, and who checks it?
- Will my unit's records be separate from the others?
- Is any part of my unit unsafe to use while drying continues?
