Flexible drinking water tanks 55, 70, 100, 160 and 220 litres
Use
Clean and sterilize the tank and pipes before using the water
supply for the first time. Sterilize the tank at least once a year,
preferably at the start of the cruising season.
Cleaning
Clean the inside of the tank with water and washing soda. Rinse
tank out with clean drinking water.
Sterilizing
Sterilize the tank and prevent algae growth at the same time by
filling with a solution of white vinegar and water (1 : 5). Allow this
vinegar solution to stand in the tank and pipes for 2 weeks.
Drain the solution and rinse the tank as follows: First rinse with
clean drinking water, then with a solution of baking powder and
clean water and then again with clean tap water.
Filling
Fill the tank with clean tap water. Always allow the water to flow
from the tap point on the wharf or jetty before filling the tank.
Never allow the tank to be pressurized by the filler pipe!
If the tank has been empty for a long time, or if the water tastes
unpleasant, repeat the above cleaning and sterilizing proce-
dures before filling the tank.
Never fill a partly empty tank, but first drain the tank before refill-
ing. The water which has been in the tank for some time may be
polluted!
Important
Always fill a drinking water tank with fresh drinking water from a
drinking water main. NEVER fill the tank from a fire extinguish-
er main.
Preventing bacterial pollution and algae formation
Water polluted with bacteria or algae has an unpleasant taste.
Chlorine tablets (Certisil® for example) can be added to prevent
bacterial pollution and algae formation. Or 0.5 to 1% of white
vinegar or chlorine bleach, as an alternative.
Bacteria and algae develop much more quickly at high ambient
temperatures than at low ones.
Winter Preparation
The tank, pipes, pump, etc., should always be drained dry.
Never add anti-freeze to the tank or other parts of the drink-
ing water system to protect against frost damage. Anti-
freeze is very poisonous!
When empty, remove the tank from the ship and store in a cool,
dry and dark place. Leave the connector nipples open to allow
the necessary tank ventilation.
Maintenance
Annually, check the hoses and hose connections for possible
leaks and fit new hoses and/or hose clips when necessary. Also
check the tank for damage caused by abrasion. Replace a dam-
aged tank immediately.
At the start of the cruising season, carry out the cleaning and
sterilizing procedures as described under “Use”.
A water installation which is seriously polluted with algae can be
cleaned by thoroughly rinsing out the tank, pump and pipes
with chlorine.
