The component that is essential for preventing flooding in low-lying areas is the sump pump. Sump pumps are specifically designed to remove excess water that can accumulate in basements or low-lying areas over time, particularly during heavy rains or melting snow. They function by collecting water in a sump basin, usually located at the lowest point of a property, and then pumping it out to a drainage area away from the foundation of the building.

By effectively managing groundwater levels and preventing water buildup, sump pumps play a critical role in protecting structures from water damage, mold growth, and other issues associated with flooding. This makes them a vital part of flood prevention strategies in susceptible locations.

While HVAC systems can help manage humidity and temperature, they do not directly address water accumulation issues. Pressure relief valves are primarily used in piping systems to relieve excess pressure, and condensate drains are intended to remove condensation from HVAC systems, but neither is designed specifically for flood prevention.
