Final answer:
The truth of the statement about the water column having at least a 3/4 inch drain pipe depends on local building codes and plumbing standards, which often set this as a minimum requirement.
Step-by-step explanation:
The statement regarding the water column having at least a 3/4 inch drain pipe is a matter of building codes and plumbing standards. While the specifics can vary based on local regulations, a common standard for the size of a drain pipe for a water column, such as the one in a boiler system or plumbing, should be large enough to allow for proper drainage and prevention of clogs. Typically, a 3/4 inch diameter is a minimum requirement for residential drainage systems, but it's crucial to check the local plumbing codes or standards for the accurate specifications required for your particular usage.
No, the statement is false. The size of the drain pipe for a water column depends on various factors, such as the volume of water being drained and the flow rate. It is not strictly necessary for the drain pipe to be at least 3/4 inch. The size of the drain pipe can be determined based on calculations or following plumbing standards.
