The fresh, grey and black water systems have each their own plumbing and tanks.

  • The fresh water system provides water to the shower on the bathing platform, to the bidet shower in the toilet compartment, and to the taps in the wet bar and in the toilet compartment.

  • The grey water system collects waste water from the sinks in the toilet compartment and wet bar, as well as from the air conditioning equipment.

    • The grey water runs from the sinks to the holding tanks below the sinks. The grey water needs to be pumped from the holding tanks to the separate grey water tank.

  • The black water system collects the waste water from the toilet.

  • The toilet operates with electricity or manually, depending on your choice of equipment. The electrical toilet uses fresh water for flushing, and the manual toilet uses sea water or lake water for flushing.

When you leave the boat unused for a longer period of time or store the boat over winter, the fresh and waste water systems will build up bacteria and impurities, or will freeze in cold weather. Before you leave or store your boat, empty the fresh and waste water systems and tanks and flush them with fresh water.
