The minimum size of the pipes connecting the boiler to the water column is an important consideration in boiler operations, as it directly impacts the efficiency and safety of the system. A 3/4 inch pipe provides adequate flow for the water column and ensures that water levels can be properly monitored and regulated within the boiler. This size allows for effective communication between the water level indicator and the boiler system, facilitating accurate readings of water levels and preventing situations that could lead to low water conditions.

Using smaller piping, such as 1/2 inch, would be insufficient for ensuring effective water movement and could result in pressure drops that hinder the performance of the water column. Conversely, while larger pipe sizes might also work, they are generally not necessary and do not offer additional benefits for this particular application, potentially leading to increased costs and complexities in the system. Therefore, a 3/4 inch pipe is deemed the minimum acceptable size to maintain efficiency and safety in the operation of the boiler system.
