The Porta Potti 165, also known as the Thetford PP165, is a sealed two-piece portable toilet that consists of an upper fresh water tank and toilet seat with lid and a lower waste holding tank. The upper tank holds a little under 4 gallons/15 litres of water for flushing. The lower tank holds approximately 5 1/2 gallons/21 litres of waste for later disposal. Unlike a septic-system attached toilet, you must prepare your Porta Potti 165 manually for use and then dispose of the waste after it fills to a certain point.
