High water velocity through a pipe tee can indeed contribute to a backflow condition, making the statement true. When water flows through piping systems, especially at high velocities, it can create conditions where pressure differentials occur. In a pipe tee configuration, if the flow rate is significantly high, it can lead to turbulence and a drop in pressure at certain points in the system, particularly at the branch of the tee.

This drop in pressure can reverse the flow direction of water if there are downstream conditions that favor backflow, such as a drop in demand or an increase in negative pressure. If there's an existing cross-connection with a potential contaminant source, the conditions created by high-velocity flow can effectively allow for unwanted backflow, putting the water supply at risk.

Other choices relate to specific scenarios that may not universally apply or imply that backflow could only occur under limited situations. However, the fundamental principle remains that high water velocity, regardless of other factors, can initiate the processes leading to backflow conditions.
