Multiply “gallons of tank capacity” by 0.13;
the result is the ounces of bleach needed to
sanitize the tank (30 gallons X .13 = 3.9 oz
bleach).
Use the number of liters of tank capacity to
determine the number of milliliters of bleach
needed to sanitize the tank (120 liters of tank
capacity = 120 milliliters of bleach).
Mix into solution the proper amount of bleach within
a container of water
Pour the solution (water/bleach) into the tank and fill
the tank with potable water.
Open all faucets (hot and cold) allowing the water to
run until the distinct odor of chlorine is detected.
The standard solution must have four (4) hours of
contact time to disinfect completely. Doubling the
solution concentration allows for contact time of one
(1) hour.
When the contact time is completed, drain the tank.
Refill with potable water and purge the plumbing of
all sanitizing solution.”
9.2 Pumps
Your boat will have both fresh water and raw water
pumps which control the flow of water to the related
components. These are electrically powered pumps.
9.2.1 Fresh Water Pump
The fresh water pump supplies pressurized water to the
system The pump is located within the port aft settee
storage compartment (Fig. 9.3).

The fresh water pump breaker switch is located on the
DC panel (refer to the DC Electric System chapter in this
manual for switch breaker details). When the breaker is
switched on, the pump will run until the hot and cold water
system is pressurized. An automatic pressure switch
shuts the pump off until the pressure drops to a preset
level (for example, a pressure drop caused by opening a
faucet). The pump will then run again until the system is
pressurized and turn itself off. The pump has a built-in
check valve to prevent backflow through the pumps.
In addition to the standard access to fresh water through
the head and galley, your boat features an optional cock-
pit shower/deck-washdown unit located on the left side of
the starboard transom garage (Fig. 9.4).
NOTE: Operate the fresh water pump only when there is water
in the tank. Running the pump dry will damage the diaphragm.
NOTE: If the pump runs from time to time even though no water
is being used, a water leak most likely exists.. Check all lines for
leaks and repair immediately.
NOTE: Whenever servicing the fresh water pump, shut off the
water pump breaker at the DC panel.
