- The mixture is 156 liters with a milk to water ratio of 7:6.

- Milk quantity is $(7 / 13) \times 156 = 84$ liters.

- Water quantity is $(6 / 13) \times 156 = 72$ liters.

- We want a new ratio of 14:13.

- Keep the milk at 84 liters, since no milk is added.

- New water quantity should be $(13 / 14) \times 84 = 78$ liters.

- Current water is 72 liters, requiring an additional 6 liters to reach 78 liters.

- Therefore, Option 4: 6 liters is the correct choice.
