What can cause hot water pipes to have reduced water flow?

Corroded piping is a common issue that can lead to reduced water flow in hot water pipes. Over time, corrosion develops within the pipe material, which can narrow the diameter of the pipe and create rough surfaces that impede the movement of water. This buildup of rust, scale, or other deposits inside the pipes can significantly restrict flow, resulting in lower water pressure and potentially inconsistent hot water availability. As the corrosion progresses, it not only affects water flow but can also lead to leaks and may even necessitate pipe replacement.

Proper understanding of how corrosion impacts plumbing systems is critical for anyone involved in plumbing maintenance or installation, as it underscores the importance of using appropriate materials, conducting regular inspections, and addressing any signs of deterioration before they lead to more severe issues.
