3 Use
Clean and disinfect the tank and the pipes before taking the drinking
water provision into use for the first time.
Disinfect the tank at least once a year preferably at the beginning of
the sailing season.
Cleaning
Clean the inside of the tank with water and soda (2 oz. / 3 US gallon).
Rinse the tank with clean tap water.
Disinfecting
When using for the first time:
Disinfect the tank by filling it with a solution of bleach in water (1 :
1000). Circulate this disinfecting mixture through the drinking water
system. Remove the solution and rinse the tank with clean drinking
water.
Calculation of the amount of common household bleach need-
ed to disinfect the tank: Use 1 millilitre of bleach for each litre
tank capacity. Or use 0.13 ounces (oz) of bleach for each US gal-
lon of tank capacity.
At the beginning of the sailing season:
Disinfect the tank and prevent the growth of algae at the same time
by filling the tank with a solution of clear vinegar in water (1 : 20).
Leave the vinegar solution in the tank for at least 24 hours, the longer
the better. 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 (2 oz. / 3 US gallon) and then again with clean tap water.
Filling
Fill the tank with clean tap water. Always run water through the pipes
from the tap on shore or the jetty before filling the tank.
If the tank has been dry for a long time or if the water has an unpleas-
ant taste the cleaning and disinfecting procedure described above
must be repeated before filling the tank.
Never top up a partly filled tank but always pump the tank empty
first before refilling it. Water that has been in the tank for a long time
could be contaminated!
The water level in the tank is visible through the tank wall!
Always fill a drinking water tank with fresh drinking water
from a drinking water pipe. Never fill the tank with water from
a fire extinguishing system.
Prevention of bacterial contamination and formation of algae
Water contaminated with bacteria or algae has an unpleasant taste.
In order to prevent contamination by bacteria and the formation of
algae, chlorine tablets can be added to the drinking water (e.g. Cer-
tisil®, not permitted in the Netherlands) or as an alternative use 0.5
to 1 % clear vinegar or bleach.
Bacteria and algae develop much quicker at a higher ambient tem-
perature than at a low temperature. Exposure of the tank to direct
sunlight also speeds up the development of bacteria and algae.

4 Making ready for winter
The tank, pipes, pump, etc. must always be drained completely.
Never put anti-freeze in the tank or other parts of the drinking wa-
ter system to protect it against freezing, anti-freeze is very poison-
ous!
5 Maintenance
- Check the breather nipple regularly and clean the sieve of the
breather nipple if necessary.
- Check the hoses and hose connections for possible leaks annually
and fit new hoses and/or hose clamps as necessary.
- Also check the tank for damage as a result of chafing. Replace a
damaged tank immediately.
- Carry out the disinfection procedures described under 'Use' at the
beginning of the sailing season.
- A tank and installation that is strongly contaminated by algae can
be cleaned by rinsing the tank, the pump and pipes with a solu-
tion of bleach in water (1:20). Rinse the tank with clean tap water.
