What are two common causes of plumbing leaks?

Two common causes of plumbing leaks include corroded pipes and loose fittings. Corroded pipes can develop weak spots as they deteriorate over time, which can eventually lead to leaks. Factors such as water quality, the type of material used in the plumbing, and age significantly influence corrosion. Over time, metal pipes may rust, leading to pinhole leaks or even larger breaches, depending on the extent of the corrosion.

Loose fittings are another frequent source of leaks. When fittings that connect pipes become loose due to factors such as vibration, temperature changes, or improper installation, they can create gaps that allow water to escape. Regular checks to ensure connections are secure can help prevent this issue.

While other causes listed may contribute to plumbing problems, they do not represent the primary culprits for leaks in the way that corroded pipes and loose fittings do. Cracked walls, for instance, may allow for water damage but are less likely to directly cause leaks at the connection points in plumbing systems. Similarly, excessive pressure can cause stress on pipes but is not as common a cause as corrosion or poor-fitting connections.
