Which of the factors listed is NOT a cause for lower water pressure?

1. Corrosion inside old pipes

2. Obstruction in the underground water line

3. Leak in the water system

4. Blockage in a house drain, specifically in the bathroom

5. Municipal water supply pressure issues

6. Incorrectly installed water fixtures

The correct answer is: Blockage in a house drain, specifically in the bathroom

The factor identified as not causing lower water pressure is a blockage in a house drain, specifically in the bathroom. While obstructions in water supply lines or systems can lead to lower pressure, blockages in a drain primarily affect the drainage system. This relates more to the removal of waste and wastewater, rather than the supply of fresh water to the fixtures. In contrast, issues like corrosion in pipes, obstructions in water lines, leaks in the water system, municipal supply pressures, and improperly installed fixtures all directly affect the flow and pressure of water supplied to a property. These factors can lead to reduced water pressure as they influence how effectively water can move through the supply lines. Understanding the distinction between supply and drainage systems is key to diagnosing issues related to water pressure effectively.
