reduces odors often associated with sea water
and reduces system maintenance.

• See Notes from Freshwater System (above).
• Seacock must be full-flow, marine quality valve (not
screw-to-close type).
• Use primary and secondary raw water filters (see
illustration).
• Position vented loop between discharge side of water
pump and toilet. Must be equipped with integral check
valve that permits air into line to prevent siphoning.
RAW WATER SYSTEM – SeaLand vacuum toilets can flush with sea water but require a separate
pump and water filtration for this purpose. Please contact your nearest VacuFlush dealer, distributor,
or Dometic Sanitation sales office for complete information.
