4K: Fresh & Waste Water Systems
4K1: Fresh Water Fill Location
There are three water tanks located in the lazarette
under the stern edge of the hatches. These are
filled by fill pipes on each. You need to fill the tanks
individually. The water level in each tank is measured
by using the wood dowel rod located on top of the
tanks.
The tanks empty uniformly when used.
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, located outboard of the port engine.
Provided the “F.W. Pump” circuit breaker is “On”, the pump will run whenever its
built-in pressure switch detects low water pressure.
The “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 precious
drinking water.
See two of the caps right by the coiled hoses? The third tank’s
cap is just left of the port side door opening to right of the picture.
The water heater is just
aft of theF.W. Pump.
Above the F.W. Pump
is its accumulator tank;
to its right is the Everhot
tank for the Furnace.
