Flush and sanitize the fresh water system at least once
every season. Flushing involves draining all water from
the system. Sanitizing involves using a commercially-
made fresh water tank sanitizing liquid that is avail-
able at many marine supply stores.
NOTE: The fresh water system, including the water
heater, must be drained as part of the winterization
process. Failure to winterize the water system could lead
to damaged pipes, valves, faucets, tanks, or a ruptured
water heater. Refer to the "Fresh Water System" por-
tion of Section 8.
Shower
If the water flow from the shower becomes restricted, it
may be due to the accumulation of sediment in the
shower head. If this happens, remove the head and
rinse it with clean water. If necessary, clean the dis-
charge holes with a narrow wire.
Water Taps
Periodically remove and clean the filter screens from
the sinks’ water taps. Rinse the screens with clean
water. If necessary, clean the screens with a narrow
wire. A buildup of debris in the filter screens can block
the water flow enough to cause the pressure water
pump to repeatedly cycle on and off.
Sumps
Clean the sumps frequently. Hair, dirt and soap scum
collect in the sumps and, if not removed, eventually clog
the sump pump or sump hoses.
Pressure Water Pump
There is an in-line filter installed near the pressure
water pump. Clean the filter once a month. The pump is
located beneath the forward hatch in the salon. Refer to
the "Interior Hatches" portion of Section 9 for the
location of this hatch.
Water Tank Vent Screen
A vent for each fresh water tank is installed through
the boat’s hull. Each vent has a screen over its opening
to prevent dirt and insects from entering the fresh
water tank. Clean the vent screens once every six
