What is the purpose of a floor drain installed in buildings?

The purpose of a floor drain installed in buildings is primarily to collect water from areas such as basements or bathrooms. These drains are designed to handle excess water that may accumulate on the floor, whether from spills, flooding, or cleaning activities. They help to prevent water damage by directing the accumulated water to a drainage system or a sewer line, ensuring that spaces remain dry and safe for use.

The function of floor drains is crucial in areas prone to water accumulation, allowing for efficient drainage and helping to maintain hygiene by reducing standing water, which can foster mold and bacteria growth. This is particularly important in bathrooms and basements where plumbing and other water sources are common.
