What is the primary purpose of manifolded drain pipes in condensate drainage systems?

The primary purpose of manifolded drain pipes in condensate drainage systems is to ensure proper sizing according to capacity. Manifold systems allow for the effective distribution of condensate from multiple sources, such as HVAC units, into a single drainage system. By doing so, it ensures that each branch of the system can adequately handle the volume of condensate produced. Proper sizing is critical; if the pipes are too small, it can lead to backflow, clogs, or insufficient drainage, which can result in water damage or inefficiency in the system.

While reducing the number of pipes, increasing pressure, or simplifying installation are benefits that can sometimes result from a well-designed manifold system, they are secondary to the essential need for capacity management in the drainage system. Maintaining effective drainage capacity is crucial for the long-term operation and reliability of the HVAC system.
