Pinhole leaks in service pipes can be problematic. To recommend repairs, home inspectors need to know the common causes of pinhole leaks in different types of pipes. Which of the following causes pinhole leaks in service pipes made from brass?
Explanation
Answer: A - Pinhole leaks in service pipes can be problematic. To recommend repairs, home inspectors need to know the common causes of pinhole leaks in different types of pipes. Pinhole leaks in brass service pipes are often caused by zinc leaching. Zinc is known to corrode brass. This occurs when zinc is removed from the alloy, leaving the metal in a weakened state. Pinholes develop over time, which allows water, air, and other elements to leak through the brass pipes. The pipes may need to be replaced with something stronger, such as copper.
