Humber/Ontario Real Estate Course 4 Exam Practice

What can potentially cause a reduction in water pressure in residential properties?

1. The use of copper piping.

2. Switching from plastic to metal piping.

3. Galvanized pipes over time.

4. Improperly installed lead pipes.

5. Usage of PVC pipes in colder regions.

6. Upgrading from older piping systems.

The correct answer is: Galvanized pipes over time.

The potential reduction in water pressure in residential properties can be attributed to galvanized pipes over time. Galvanized pipes are coated with a layer of zinc, which helps prevent rust and corrosion initially; however, as time passes, these pipes can corrode from the inside. This corrosion leads to a buildup of mineral deposits, which can significantly narrow the diameter of the pipes and obstruct water flow. As a result, the water pressure within the plumbing system decreases. The age of galvanized pipes often plays a significant role in their deterioration, as older systems may have been in place for decades, allowing enough time for corrosion to accumulate. When considering the implications of upgrading or changing plumbing systems, it's important to recognize that while some materials may have advantages, galvanized pipes are often a source of reduced water pressure due to long-term wear and tear.
