WASTE WATER SYSTEM
Overview
The waste water system includes the 65 gallon capacity
waste tank located under the main salon fl oor. Besides
the tank the system features two toilets and waste pump-
out fi tting mounted at the starboard amidships deck. A
monitor panel shared with the fresh water system displays
the waste tank level when activated. If installed, a macerator
(overboard discharge pump) diverts waste through a hull
bottom seacock (where dumping laws permit).

There is a waste fi lter in-
stalled in the vent line be-
tween the waste tank and
the port thru-hull fi tting
(accessible behind the aft
galley. The fi lter’s purpose
is to keep objectionable odors to a minimum from the
waste tank. It is recommended that the fi lter be changed
yearly. It can be ordered from your Regal yacht dealer or
from marine supply stores.
The vent fi lter is comprised of a union on both ends.
This makes it easier to change out the main fi lter body.
Unscrew the unions and remove the fi lter. It may require
the use of water pump type pliers to brake the unions
loose.
Use tefl on tape on the new fi lter ends before reinstall-
ing on the unions. Normally wind 2 to 3 even bands on
the threads to assure proper thread sealing. Tighten the
unions making sure you do not cross thread. Make fi nal
connections with adjustable water pump pliers.
