What is a common result of improper plumbing installation?

Improper plumbing installation often leads to an increased risk of leaks and damage, making this the accurate answer. When plumbing systems are not installed correctly, it can create issues such as loose fittings, misaligned pipes, and insufficient sealing, which can eventually result in water leaks. These leaks can cause significant damage to the structure of a building, lead to mold growth, and result in costly repairs. Additionally, faulty installations can lead to water pressure problems that exacerbate these risks further. Thus, the consequences of improper installation highlight the importance of professional and accurate plumbing work to prevent future complications.

While improvements in water flow, increased energy efficiency, or reductions in water usage can often be outcomes of properly installed plumbing systems, these benefits are unlikely to be realized in cases of poor installation, which typically leads to deterioration of functionality instead.
