9.1 Water Tanks (on board water supply)<br />
The fresh water system on your boat has one water tank<br />
totaling 20 gallons ( 75L) and one fresh water fill (Fig. 9.1)<br />
located at the bow. The vent for the tank is located on the<br />
side of the hull, at the fill. See the arrangement drawing<br />
at the end of this chapter for locations.<br />
! CAUTION !<br />
Always ensure that when filling the fresh water tanks<br />
that you are filling through the fresh water fill. Other<br />
fills or pump outs may visually look the same. Filling<br />
fresh water in to the waste pump out could flood<br />
your boat, or filling the diesel fuel tank could damage<br />
your fuel system.<br />
9.1.2 Fresh Water Sanitation<br />
NOTE: Be sure and read the OEM manuals that are supplied<br />
with your boat, the next section is taken from one of those<br />
manuals.<br />
Sanitizing Potable water systems require periodic maintenance<br />
to deliver a consistent flow of fresh water.<br />
Depending on use and the environment the system is<br />
subjected to, sanitizing is recommended prior to storing<br />
and before using the water system after a period of storage.<br />
Systems with new components, or ones that have<br />
been subjected to contamination, should also be disinfected<br />
as follows:<br />
NOTE: The sanitizing procedure is in conformance with the<br />
approved procedures of the US Public Health Service.)<br />
1. Use the following methods to determine the amount of<br />
common household bleach needed to sanitize the tank:<br />
A. Multiply “gallons of tank capacity” by 0.13; the result<br />
is the ounces of bleach needed to sanitize the tank (30<br />
gallons X .13 = 3.9 oz bleach).<br />
Note: Whenever servicing the fresh water pumps, shut off the<br />
DC breaker for the water system.<br />
9.1.1 To fill the fresh water tank:<br />
1. Make sure the potable water supply is suitable for<br />
drinking. Not all potable water is drinking water. Check<br />
with the dockmaster if necessary.<br />
2. Open the water tank fill fitting. Fig. 9.1<br />
3. Using the hose from the potable water supply, fill the<br />
tank until water starts flowing through the vent.<br />
4. Close the fill fitting.<br />
B. Use the number of liters of tank capacity to determine<br />
the number of milliliters of bleach needed to sanitize<br />
the tank (120 liters of tank capacity = 120 milliliters of<br />
bleach).<br />
2. Mix into solution the proper amount of bleach within a<br />
container of water<br />
3. Pour the solution (water/bleach) into the tank and fill<br />
the tank with potable water.<br />
4. Open all faucets (hot and cold) allowing the water to<br />
run until the distinct odor of chlorine is detected.<br />
5. The standard solution must have four (4) hours of<br />
contact time to disinfect completely. Doubling the solution<br />
concentration allows for contact time of one (1) hour.<br />
9.2<br />
6. When the contact time is completed, drain the tank.
