TYPICAL SHOWER SUMP PUMP
The gray water system is primarly designed to handle the
used sink, shower and air conditioning pan water. The
system passes used water through the shower sump pump
and eventually is discharged into a tank. The different
hoses routed to and from a typical shower pump are indi-
cated below.

MARINE SANITATION REGULATIONS
All boats with fixed toilets used in U.S waters and various
waters worldwide are required to be equipped with an
operable marine sanitaiton device (MSD). Our electric
marine toilet systems use holding tanks and are defined
as Type III by the U.S. Coast Guard.
Type III systems are designed to permit operation of the
toilet without the direct discharge of untreated waste after
every flush. This means the system can be used when the
vessel is near shellfish, beaches or swimmers.
Type III systems can be discharged at marina dockside
pump-out stations or, if in coastal waters, a minimum of
3 miles offshore. Overboard discharge capability must
be secured while within the three-mile limit. The
overboard discharge pump is activated by a keyed switch
located at the monitor panel. This key must be removed
at all times except when discharge pump is
operating.
TYPICAL WASTE SYSTEM FILTER
An in-line waste filter is installed in the vent hose between
the waste tank and the waste vent thru-hull fitting. It acts
as a waste system odor absorption device to keep waste
tank odors under control. It is recommended that the filter
be changed yearly. Call your authorized Regal yacht dealer
for more information. The filter is located in the bilge.
