Which of the following statements about water pressure is false?
- Water pressure can fluctuate slightly with the seasons or time of day.
- For any given address, water pressure is relatively consistent and minor fluctuations are normal.
- Water pressure changes only occur if there is a water main break.
Answer: C is false.
While a main break can cause low water pressure, there are other reasons why water pressure might change.
For any customer, water pressure is fairly consistent but can vary slightly due to changes in water tank levels or seasonal or daily changes in water use. For example, in residential neighborhoods, daily peak use is before and after normal business hours and seasonal peaks occur during the summer irrigation season. During these peak use periods, customers may experience lower water pressure than at night or in the winter. Pressure will also fluctuate inside a home based on how many faucets or appliances are running at one time.
