Pool Plug Marimex Swing

This is a custom-designed plug intended to block or seal the water outlet/inlet of a swimming pool, typically at the connection point leading to the filtration pump. It prevents water from leaking out or air from entering the system when the pump is disconnected or undergoing maintenance. The part fits into the threaded or smooth port and is usually made of plastic or a 3D-printed material. Ideal for seasonal pool closures, testing, or temporary isolation of pump systems.
