Within how many feet of each water storage tank or water heater should a shut off valve be provided in the Coldwater Branch line?

  1. 3'

  2. 5'

  3. 7'

  4. 10'

The correct answer is: 5'

Providing a shut-off valve within 5 feet of each water storage tank or water heater in the Coldwater Branch line is essential for several reasons. This proximity allows for easy access to the valve in case of maintenance, repairs, or emergencies, ensuring that the water supply can be quickly interrupted to prevent flooding or damage. The Illinois Plumbing Code emphasizes accessibility and safety, making the 5-foot requirement an important standard. This distance strikes a balance between convenience for maintenance personnel and the practical layout of plumbing systems in homes and facilities. Being too close to the appliance may complicate access, while being too far could impede quick action in emergency situations. This standard is critical for plumbing efficiency and safety, and adhering to it helps to ensure compliance with the plumbing regulations set forth by the state.
