FRESHWATER SYSTEM
This system is best winterized with one of the non-toxic antifreezes available for use in
boat and recreational freshwater systems. It is an easy method, which replaces fresh
water with a non-toxic antifreeze mixture.
Caution! Be sure to use non-toxic antifreeze.
1. Allow the water in the water heater to cool, and open the pressure release valve on top.
Disconnect the hot and cold water hoses and allow the tank to drain either in a bucket
or into the bilge. Connect and clamp the hot and cold water hoses together using a
short length of 1/2" pipe in order to bypass the heater.
2. Mix the appropriate amounts of antifreeze and water, as directed on the label, to
deliver the degree of protection desired. Put 1-1/2 to 2 gallons of the solution into
each water tank.
3. Open both tank selector valves on the manifold.
4. Turn on the pump and open all fixtures until antifreeze runs through. Be sure to open
the hot water selector valve in order to supply antifreeze to the hot water hoses and
through the bypass loop.
5. At this point, the freshwater system should be completely protected by antifreeze
against freezing to a degree indicated by the strength of the solution placed into the
supply tanks.
6. New boats delivered have their freshwater systems filled with antifreeze as described
above, and are protected to -30 degrees F.
HEAD
Several days before completing haul-out procedures, fresh water should be allowed to
stand in the head unit to dissolve any salt accumulation in the hoses and pump. Remove
all water from the head. Special lubricants for the pump' s internal mechanism are
available. Check with your marine hardware dealer for a recommended brand. Never put
oil, gas, kerosene, or alcohol in the head or they will ruin the internal valve.
Completely pump out all waste from the holding tank and pour in a cleansing, deodorizing
solution. If possible, allow this to sit in the tank overnight, then completely pump out and
drain the entire system. If antifreeze is used in the system, check in the manufacturer' s
literature for the recommended type.
