6.3 GREY WATER SYSTEM
The waste water from the showers and sinks is collected by an 535 l waste
water tank located under the left-hand guest cabin and it’s connected to the
evacuation pump located in the engine room.
ENVIRONMENT
Do not discharge soaped waters drained by washing machines and dish-
washers in the harbour, inside marinas or near beaches, because of the
large amount of foam produced.
The grey water pump, in automatic mode, primes when the liquid level
reachestheoatandisswitchedoffbyatimer.Ithastoberemembered
thattheoatinsidethegreywatertankisequippedwithacircuitdelayingfor
some second, both the pump switching on and off.
The start delay prevents that, in case of yacht rolling, the pump primes with
the wake.
The switching off delay ensures that the pump sucks also the residual liquids
belowtheoatlevel.
