When sizing water lines, what should be considered?

  1. The distance to the main water source

  2. The material of the pipes

  3. All fixtures will be on

  4. The color of the pipes

The correct answer is: All fixtures will be on

When sizing water lines, the primary consideration should be the demand for water from all fixtures that will be using it. Option A may be relevant in terms of the overall length of the water line, but the demand for water will also depend on the number of fixtures connected. Option B is important for the longevity and durability of the water line, but it does not directly affect the sizing of the line. Option D has no impact on the sizing of water lines. Therefore, option C is the most important factor to consider when sizing water lines.
