Emptying

The longer polluted water has been in the tank the greater the risk of

nuisance from smell. Therefore, never leave a waste water tank filled

unnecessarily long, but pump the tank empty or have it pumped

empty once a week, or whenever possible.

Pumping empty can be done in two ways:

1. by connecting a shore pump-out system to the deck cap to pump

the tank empty.

2. by using a pump present on the ship to pump out the waste water

directly overboard through the deck cap and a hose connected

to this. This pump must have internal diameter of minimum ø 38

mm (1½ inch).

Pumping waste water directly overboard is

in many places absolutely not allowed!

If the tank is pumped empty by a high capacity pump there is a risk

of the tank collapsing due to the reduced pressure caused. This prob-

lem occurs particularly when using the pump-out systems. The fol-

lowing measures can be taken to prevent collapsing from occurring:

- open the inspection cover on the tank

- open a shut-off valve fitted to the tank for this purpose

- install an automatically working blow valve.

During your absence

The water in the siphons can evaporate when no use is made of

washbasins, showers etc. for a long time (siphons act as smell traps

in the pipes). This causes smell nuisance. Therefore, place plugs in all

drains when the ship is not to be manned for a longer period.

Disinfect the tank and pipes at least once a year preferably at the end

of the sailing season.

Cleaning

'Grey water' tank

Clean the inside of the tank with water and a good degreasing house-

hold cleaner; use a brush or a sponge for a rigid tank. Rinse the tank

with clean tap water.

'Black water' tank

Clean the inside of the tank with water and a good toilet cleaner; add

cleaning vinegar if there are lime deposits; use a brush or a sponge

for a rigid tank. Rinse the tank with clean tap water.

If required, add to reduce odors 'Tank Fresh' .

Disinfecting

Disinfect the tank by filling it with a solution of bleach in water (1:

1000). Circulate this disinfecting mixture through the waste water

system. Remove the solution and rinse the tank with clean tap water.

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!

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.
