4K: Fresh & Waste Water Systems
4K1: Fresh Water Fill Location
There are two water tanks filled by fills on the side decks (labeled “WATER”). Do
not overfill the water tanks, lest you damage the vent filters. Stop filling as soon as you hear
the water coming up the tank standpipe.
Be sure to use the "water" fills, not the "waste" deck fittings!
4K2: Fresh Water Heater
After the water pump, water is distributed directly to the cold water faucet lines. In
addition, it goes to the boat's water heater. The heater uses two energy sources, (1) heat from
the engine, so that whenever the boat is running, or has recently run, there is hot water; and
(2) 110 volts AC from shore power or generator, if available and the heaters' 110-volt AC
breaker is "on". The heater is insulated well enough to keep hot water overnight without power,
provided you haven't wasted a lot.
4K3: Fresh Water Pump
The water line from the tanks leads to the boat's fresh
water pump that are located to port just forward and outboard of
the port engine.
Provided the correct "F.W. Pump" circuit breaker is
"On", the pump will run whenever its built-in pressure switch
detects low water pressure.
The blue "accumulator tank" by the pump provides a
"pressure head" for the pump, so the pump doesn't need to run
so often. Instead, a pump cycle will provide for several minutes
of routine water use before pressure diminishes and the pump starts again.
It is a good idea to turn off the fresh water pump breaker whenever
leaving the boat for any extended period, lest a dripping faucet or
broken hose cause the pump to run and waste your water.
4K4: Fresh Water Tanks
The combined tanks hold 500 gallons. The tanks are under the forward stateroom
berth and in the lazarette; water from the forward tank flows to the aft tank where it then is
piped to the water pump.
4K5: Waste Water
Waste water from the sinks and showers (but not from the toilets) is dumped
overboard in accordance with U.S. and Canadian law. From sink basins, the water simply
flows by gravity overboard. Since the floor of the showers and the bottom of the engine room
sink are below the water line, built in shower sump pumps operate to lift this water back above
the waterline and dump it overboard.
It is therefore very important that the “drain pump” breaker in the
DC panel be left “On”, and that the “Drain Pump” switches at
each shower and the engine room sink also be “on”.
Fresh water pump is under blue
accumulator tank.
