flush Water options
FRESH WATER SYSTEM – VacuFlush vacuum toilets 

can flush with fresh water or sea water. Fresh water 

is highly recommended because it 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 – VacuFlush 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. 

Vented loop must be at 

least 8 inches [203mm] 

above water line in toilet 

during all conditions of 

heel, trim or load.
