28 CHAPTER 6: PLUMBING
Marine Head With Holding Tank
• Your boat is equipped with a marine head (toilet) and waste holding tank system.
• Read the manufacturer’s operation and maintenance manual (included in your boat’s owner’s packet).
• The holding tank is plumbed to a waste fitting on the deck for dockside pump-out.
• You can determine the content level of the holding tank by looking at the side of the tank.
• Empty the holding tank at every opportunity.
Electric Flush Marine Head (If Equipped)
• The electric flush marine head uses seawater to flush waste from the toilet into the holding tank.
• The seawater intake valve (seacock) must be open for the head to work.
