What should the pressure system of a private water supply system provide?

1. A visually appealing water stream

2. The peak demand

3. A fixed volume of flow regardless of demand

4. Energy efficiency

The correct answer is: The peak demand

The other options are incorrect because they do not accurately describe the purpose of the pressure system in a private water supply system. Option A, providing a visually appealing water stream, may be a desirable outcome but it is not the main purpose of the pressure system. Option C, providing a fixed volume of flow regardless of demand, is not efficient or practical as it could lead to water wastage or inadequate supply. Option D, ensuring energy efficiency, is important but it is not the main purpose of the pressure system. Option B, providing the peak demand, is the correct answer because the pressure system should be able to meet the highest demand for water from the private supply, ensuring a continuous and adequate supply for the users.
