Humber/Ontario Real Estate Course 2 Exam Practice

Which of the following is NOT a cause of lower water pressure?

1. A blockage in one of the drains, particularly one near a bathroom.

2. A leak somewhere in the water system within a home.

3. An obstruction in the underground water line leading from the municipal watermain on the street to the house.

4. Corrosion inside galvanized pipes in an older home.

5. A malfunctioning water pressure regulator.

6. Excessive use of water during peak hours.

The correct answer is: A blockage in one of the drains, particularly one near a bathroom.

Option A states that a blockage in one of the drains, particularly one near a bathroom, is NOT a cause of lower water pressure. This is the correct answer because blockages in drains do not typically impact the overall water pressure in a home. Issues such as a leak in the water system within the home, an obstruction in the underground water line, corrosion in pipes, malfunctioning water pressure regulator, and excessive water usage during peak hours are all potential causes of lower water pressure. However, a blockage in a drain is specific to that particular drainage system and does not usually affect the general water pressure throughout the house.
