A leaking seal on the oil pump can cause oil to leak where?

In the storage tank
On the floor in front of the heating unit
In the combustion chamber
In the chimney

The correct answer is: On the floor in front of the heating unit

A leaking seal on the oil pump primarily causes oil to leak onto the floor in front of the heating unit. When the seal fails, the oil that is being pumped to the burner can escape from the pump and accumulate on the floor directly beneath it. This leakage is a sign of mechanical failure and poses risks such as fire hazards and environmental contamination. In contrast, a leak in the storage tank would generally involve different mechanical issues related to the tank itself or its connections, while oil leaking into the combustion chamber or chimney would indicate much more severe and unusual failures, as these areas are designed for air and combustion gases, not for liquid fuel. Recognizing the specific location of potential leaks helps maintain the safety and efficiency of a heating system.
