True or False: Condensate drain lines shall have a trap installed.

Installing a trap in condensate drain lines is essential for preventing the backflow of air, smells, and contaminants into the system. Traps create a water seal that blocks air and undesired elements from entering the drain line, ensuring proper drainage of the condensate produced by equipment such as air conditioning units and refrigeration systems. This practice helps maintain the efficiency and hygiene of the system by allowing condensate to flow freely while preventing undesirable ingress.

In certain settings, including residential, commercial, and marine applications, traps are a standard requirement, making the statement true. The need for traps is not limited to specific scenarios or types of systems; rather, it is a fundamental practice across various environments to ensure the integrity and proper functioning of the drainage system.
