The above diagram shows how water will enter into the pool filter inlet port and is forced through filtration media (Cartridge, DE, Sand) to leave behind any debris when exiting the filter from the returning port. Generally in most swimming pool filter models both of the inlet & outlet ports are close together and are called the bulkhead assembly. The inlet receives dirty water from the pool pump, and the outlet sends clean water back to the pool.
