Maintenance of black water tank

- The risk of unpleasant odours forming increases when the waste water remains in the tank 

for a long time.

- Whenever possible empty the tank regularly even before it is full.

- Every time the tank is emptied put in about 5 litres of fresh water and add an appropriate 

detergent additive (available from chandleries). A very simple method is soda salts, which 

clean and disinfect at the same time.

- Before winterising, flush the tank with copious amounts of fresh water filling it through the 

'WASTE' deck connection. Leave at least 5 litres of fresh water mixed with a detergent additive.

- Disinfecting: Disinfect the tank once a year by filling it with a solution of Javel water (1 to 

1000).

- Never use automobile anti-freeze in the black water system: risk of 

poisoning.

ADVICE-RECOMMENDATION

- Respect local regulations regarding the emptying of black water tanks.
