MasterFlush 8900RV Series Toilet System
RV system layout
SeaLand MasterFlush 8900 series macerator toilets operate with a pressurized freshwater
system, and require a minimum flow rate of 2.0 gpm (7.6 lpm) at the toilet with a static pressure
of 30-100 PSI/206-689 kPa. Fresh-water demand systems include a water pump that
automatically draws water from a water storage tank when a valve anywhere in the piping
system is opened.
MasterFlush 8900 series toilets are equipped with an electrically operated water valve and an
atmospheric vacuum breaker to prevent contamination of fresh water supplies. The system
can be equipped with a waste tank level monitor and shut-down relay that, when connected to
the “full” level probe of the waste tank, shuts off power to the toilet when the tank becomes full.
This prevents overfilling the waste tank.
