⚙️ HOW IT WORKS / FUNCTIONALITY
The Porta Potti 345 uses a manual piston pump that draws fresh water from the 15L flush tank to rinse the bowl after each use. Waste is securely contained in the 12L holding tank, which seals completely to eliminate odours. The vent button ensures easy, splash-free emptying when the indicator shows the tank is full.
