Which of the following is an example of physical deterioration?

Physical deterioration refers to the decline in the physical condition of a property due to wear and tear, aging, or damage over time. This can manifest in various structural elements and systems within a building.

Leaky plumbing is a prime example of physical deterioration because it indicates a malfunction or degradation of the plumbing system. It shows that the pipes may have corroded or that seals have failed, leading to water damage and potential further deterioration of surrounding structures. Such issues arise from ongoing use, environmental factors, and the natural ageing process of materials.

In contrast, low-hanging pipes, a low-capacity furnace, and inadequate plumbing may reflect issues of design, insufficient installation, or capacity but don't inherently demonstrate the deterioration of materials or structural components. Therefore, leaky plumbing distinctly signifies ongoing physical deterioration within the property.
