Septic tank

IMPORTANT

If the boat is fitted with a septic tank (made out of acidproof steel) there is a 3-way cock next to the bowl, which selects emptying either into the tank or the sea. The tank is large enough for about 20 operations.

When on the open sea the tank can be emptied with a mechanical pump after the seacock under the tank has been opened. Rinse the tank after each emptying by pumping it full and emptying it a couple of times. This will lessen the risk of clogging very much.

If you want to eliminate vapours due to gas expansion in the tank, we recommend Natriumhypochlorite (NaClO), which will also dissolve the toilet paper to a certain extent, and lessen the risk of clogging. Consult your pharmacist, who will supply you with the substance and instructions for how much to use.

Do not add it into an empty tank!

We do not recommend the chemicals intended for caravan toilets, since they strongly contribute to pollution of the sea. The NaClO will react in the tank and turn into table salt.

After use at sea, empty the bowl completely by pumping a few strokes the lid open, in order to prevent splashing due to the movements of the boat.
