Plumbing System
5.1 Fresh Water System
General
The fresh water system consists of a potable
water tank, distribution manifold, distribution
lines and a distribution pump. The pump is
equipped with an automatic pressure switch
and is located in the machinery space. An
in-line strainer located near the pump pro-
tects the system from debris. The tank,
located under the cabin sole, is filled through
a labeled deck fill located on the gunwale.
DO NOT confuse other deck fill with fresh
water fill. If toxic fluids or fuel is added to
fresh water tank, the system will be contami-
nated. DO NOT attempt to pump fuel out;
this system is not designed to pump fuel.
Fuel must be removed by qualified personal
only. Fuel in the fresh water systems will
also require replacement of that system and/
or many components.
Operation
Fill the water supply tank slowly through the
FRESH WATER FILL deck plate. After filling
tank, partially open all faucets. Turn on
“Fresh Water System” switch at the helm.
Allow the pump to run until all of the air is
purged from the system and a steady stream
of water is flowing from each outlet. Next,
turn off the faucets one by one. As the pres-
sure builds, the pump will automatically shut
off.
When properly primed and activated, the
water system will operate like the water sys-
tem in a home. An automatic pressure sen-
sor keeps the system pressurized. If the
system has been recently filled or has not
been used for an extended period, air may
accumulate at the pump and the system
may have to be re-primed.
The water system manifold, located on the
starboard side of the machinery space, pro-
vides a shutoff valve for each fixture in the
boat. Each line is a “home run.” There are
no fittings between the manifold and the fix-
ture to leak or fail. Should a problem occur
with any plumbing fixture in the boat, shut off
the appropriate valve to isolate it while leav-
ing the remainder of the system operational.
See the schematics section for additional
information on the water system manifold.
Whenever the boat is left unattended, turn
the fresh water system switch "OFF."
Sink and Shower Operation
To use the galley sink, head sink or shower
turn on the fresh water system. Some minor
variations in the water temperature and
pressure may occur as the pump cycles.
The sinks drain overboard.
Water drains from the shower to a sump
pump system located in the bilge below the
the aft berth. An automatic float switch in
the shower sump controls the pump. After
showering, let the cold water flow for a
period of time to flush the drainage system
of soap residue. It is essential that the
shower drain strainer is cleaned regularly
!
DANGER
FIRE OR EXPLOSION HAZARD
Fuel and their vapors are highly explo-
sive when exposed to open flame or
spark, resulting in death or serious
injury. Do not confuse deck fills.
!
CAUTION
DO NOT allow the fresh water pump to
run dry; damage to the pump can
occur. The fresh water pump works on
demand and WILL NOT shut off when
the tank is empty. Turn the water
pump switch "OFF" when the system
is not in use. Operating any pump
from a low-charged battery can lead to
a pump failure. Keep the batteries
properly charged. The fresh water
system must be properly winterized
prior to winter lay-up. Refer to Winter-
izing.
