Failure simulations
Step through the physical route from trigger to symptom, then see what evidence would support or weaken the pathway.
Cooling condensate drain overflow
A blocked, disconnected or poorly sloped drain allows cooling condensate to wet nearby finishes.
- Cooling coil removes moisture from air.
- Condensate collects in a pan.
- Drainage is restricted or disconnected.
Heating pipe thermal expansion creates clicking
Pipe length changes during warming and cooling, producing repeated frictional releases at penetrations and clips.
- Heating starts or stops.
- Pipe temperature changes.
- The pipe expands or contracts.
