What is the primary purpose of a floor drain trap?

The primary purpose of a floor drain trap is to hold water and prevent odors. A trap is a crucial element in plumbing systems because it maintains a small amount of water in the bend of the trap itself. This standing water acts as a barrier, effectively blocking sewer gases and odors from escaping into the building. The trap essentially functions as a seal, ensuring that unpleasant and harmful odors are kept at bay, making indoor environments healthier and more comfortable.

Maintaining this water barrier is essential, as it helps to ensure that the plumbing system operates correctly. The need for proper water levels in the trap is why regular monitoring and maintenance of floor drains are important, especially in environments where they may go unused for extended periods. This also illustrates the significance of an effective plumbing system in terms of sanitation and comfort in buildings.
