40 Hour Property and Building Inspection Practice Test

If a home inspector notices a rotten egg smell when entering a vacant home, what should they inform the client about?

1. It is safe to run the dishwasher

2. It is due to poor ventilation in the home

3. It may indicate an issue with the sacrificial anode in the water heater

4. It is a common issue in all homes

The correct answer is: It may indicate an issue with the sacrificial anode in the water heater

A rotten egg smell in a vacant home is typically associated with the presence of sulfur compounds, which can be indicative of a specific problem within the plumbing or appliances related to the water supply. The presence of such an odor is commonly associated with hydrogen sulfide gas, which can be produced by decaying organic matter or can also be a result of reactions involving certain metals, particularly in water heaters, such as the sacrificial anode. The sacrificial anode is a component of a water heater designed to corrode in place of the metal tank, and it can produce hydrogen sulfide gas when it degrades, leading to that unmistakable rotten egg smell. Therefore, informing the client that the smell may indicate an issue with the sacrificial anode in the water heater is crucial. This information allows the client to take necessary actions to address the issue, such as inspecting and possibly servicing the water heater, which could prevent further damage and ensure safe water quality. Understanding the implications of this odor can lead to a timely resolution of potential hazards, promoting the overall safety and functionality of the home.
