A return pipe is the part of a piping system that carries fluid back to its source or a central processing point after it has served its purpose.
In the context of a swimming pool or spa, a return pipe is specifically the section of piping between the filter and the pool or spa through which the filtered water flows back into the pool. This is often referred to as "effluent piping."
Here's a breakdown:
- Purpose: Its primary function is to transport the cleaned or treated water back into the system from which it originated.
- Pool/Spa Example: In a pool or spa, the return pipe delivers the filtered water back into the pool after it's been cleaned by the filter system. The water is typically drawn from the pool via skimmers and the main drain, then pumped through the filter, and then returned to the pool via the return pipe.
- Importance: A properly functioning return pipe is critical for maintaining water quality and circulation. It ensures that filtered water is evenly distributed throughout the pool or spa.
Therefore, whether generally or within a swimming pool context, a return pipe is a key component for closed-loop systems where fluid is re-circulated.
