Where should the valved drain lines be located in water supply tanks?

  1. Above the tank

  2. At the center

  3. At the bottom

  4. At the lowest point

The correct answer is: At the lowest point

Valved drain lines in water supply tanks should be located at the lowest point. This placement ensures effective drainage of the tank, as any accumulated water or sediment will naturally flow towards the lowest part of the tank where the drain line is situated. Having the drain line at the lowest point also helps in the maintenance and cleaning of the tank, allowing for thorough removal of any residue that may have settled at the bottom. Therefore, placing the valved drain line at the lowest point is the most practical and efficient choice.
