WATER
SYSTEMS
The
water systems on the boat may be logically divided into the following
groups: fresh water, raw water, gray water, black water, air conditioning,
bilge drains, and bait tank. The fresh water system may be sub-divided
into hot and cold supply. All fresh water is plumbed with rigid
plastic tubing. The hot water plumbing is red and insulated; the
cold water is plumbed with blue tubing. The raw and gray water systems
are plumbed with flexible hose and ABS pipe, the black water system
is plumbed with white sanitation hose and PVC, and the bilge water
systems is plumbed with clear plastic hose with green plastic reinforcement.
FRESH WATER
The fresh water system consists of two fills, a total of 800 gallons
in a tank located under the master stateroom, a 1500 gallon-a-day
water maker, AC and AC backup water pumps pressurizing an expansion
tank and supplying hot and cold water. Filling is accomplished in
one of three methods. The typical method is to supply water to the
connector found on the forward bulkhead in the lazerette. This line
runs through a flow meter, fine ceramic filter, taste and odor filter,
UV light and into the water tank. The ceramic filter is rated for
a flow of one gallon per minute. Give yourself time to fill! The
second method is to use the water maker itself. The output of the
system tees into the aforementioned plumbing at the UV light. The
third method is to fill the tank directly from a deck fill located
on the deck just forward of the port pilothouse door. The fresh
water pumps and additional filters are located in the "pump room",
forward of the port guest cabin. Access is made thorough the hanging
locker. Between the water tank and the water pumps is a mesh screen
filter. This screen should never have anything in it but should
be checked on occasion anyway. The water pumps are plumbed in parallel.
The starboard water pump is a 240V AC unit that runs directly off
of the AC panel. The port pump is a 110V unit wired through the
inverter. The pumps feed sediment and a taste and odor filters before
the water flows into an expansion tank, then out into the hot and
cold water systems. If water pressure takes a long time to build
up or the volume is low, replace the filters. The expansion tank
and water heaters are located on the starboard side outboard of
the port guest head. Access is gained through the guest bath for
the port guest room. Lift the mirror and strap it to the overhead
and then tip out the shelf box and climb in.. The heaters are labeled
#1 and #2 on the AC panel.
GREY WATER
The Gray Water System consists of a holding tank, associated plumbing,
and a 24V DC pump. Water flows from sinks, showers, and the washing
machine into the gray water tank and then is pumped overboard automatically.
Automatic operation is discussed in the Tank Tender section of this
manual. The gray water pump is located in the pump room, mounted
on the aft bulkhead. This pump requires regular maintenance. There
are inlet and outlet duckbill valves that wear out. If the pump
should run for more than ten minutes or if the valves have not been
checked in six months or more, check it out. The gray water holding
tank is located in the forward section of the bilge under the port
guest stateroom.
BLACK WATER
The head/black water system is based on a set of Royal Flush fresh
water jet flush toilets, holding tank and pump. The tank is located
in the after section of the mid bilge and the pump is located in
the engine room in the aft starboard corner. The tank can be pumped
automatically. See the Tank Tender section for a discussion of pumping.
The gray and black water tanks are attached at the top, which will
allow overflow from one into the other. The black water pump has
been set up to double as an emergency bilge pump for the engine
room. A valve located just inside of the aft door under the engine
room sink swaps the pump pickup between the black water tank and
a hose under the transmission. To run the pump manually you can
use the rotary switch located on the panel just aft and above the
engine room sink. This will also facilitate pumping the black water
tank dry. A deck fitting is located under the sink in the cockpit
for pump-out at a dock or to run fresh water back into the black
water tank for flushing or for priming the pump. There is a three-way
valve in the engine room, plumbed just before the black water pump
which must be flipped to enable use of the deck pump-out.
RAW WATER
All raw water is supplied through the sea chest located in the
port aft corner of the engine room. There are seven outlets off
of the sea chest, each having their own valve and sea strainer.
The supplied systems are: Main Engine Engine exhaust Engine cooling
system heat exchanger Shaft bearing cooling/lubricating water Stabilizer
cooling system heat exchanger Forward generator Aft generator Water
makers Air-conditioner Thruster/Hydraulic system heat exchanger
Cooling water for the hydraulic system has it's own sight gauge
and discharge connected to the discharge sea chest in the starboard
corner of the engine room.
WATER MAKERS
The water maker components are all located in the lazarette on
the starboard side. Seawater is drawn through the sea strainer found
close to the inlet sea chest and through the boost pump located
by the lazarette hatch, then fed through a flow meter to the plankton
filter and on to the pool style sediment filter. The high-pressure
pump pulls water from there and sends it through the RO filters.
Brine is dumped overboard and fresh water is fed through the UV
filter into the water tank. Within the restrictions discussed in
the water maker system manual, the unit is normally run at 850psi.
The UV light is not automatically switched with the water maker.
The switch for the UV light is in the light switch fixture next
to the hatch. Now that there are two water makers the valving is
somewhat more complicated. Starting at the lazarette bulkhead and
running towards the water makers the valving is as follows: Watermaker
plumbing diagram Shutoff valve isolating both water makers Shutoff
valves at each boost pump Fresh water flush valve (to the right
of the boost pumps) From the boost pumps the water flows through
the systems and to two more sets of valves. These are located outboard
on the forward bulkhead of the lazarette forward of the water makers.
The Sea Recovery valves are the inboard valves, one red and one
green. The Vantage valves are the outboard red/green pair. DO NOT
turn on either water maker unless you have checked the valving and
understand what is going on. If a system is turned on with any of
the output valves shut the water maker WILL pop one or more hoses
and possibly damage the RO membranes. The safest thing to do is
leave all of the valves on the bulkhead open. Finally, after the
red handled pair of valves (brine dump) there is a three-way valve
that is used then cleaning or pickling the system. The output of
this valve either goes overboard or feeds into the fresh water flush
line aft of the water makers. This allows circulation of water within
the system. After each use of the system the filters should be flushed
with fresh water. When it comes time to pickle or clean the system
there is an addition valve on the brine discharge line, mounted
on the bulkhead above the UV light. This allows circulation of the
cleaning or pickling solution. One additional complication is that
there is no three-way valve on the fresh water output. When circulating
cleaning solution or pickling solution the water maker systems will
sense fresh water in the system and allow the solution to go into
the fresh water tank. To prevent this, disconnect the wire to the
three-way valve on each water maker. The Vantage unit's valve is
mounted on the aft side of the control box, and the Sea Recovery
unit's valve is mounted on the bulkhead.
