We don't want a boat with bad smells so now is the time to winterize the toilet and blackwater system, especially if you won't be using them for more than 3 months.

By carrying out some simple maintenance tasks on the toilets and tanks, we will avoid finding the unpleasant smell on the boat when we return.

Carrying out a correct wintering will allow us to be prepared to go out with the boat again, at any time.

At Dahlberg we advise you to check and clean the following points of your sewage system:

· Toilet bowl
· Electric bomb
· Hose circuit
· Level sensors
· Storage tank

The cup of the bathroom: in the event that there are dark or lime stains, we will apply a descaling or stain remover product to leave the bowl spotless. It must be a product that does not damage the joints and parts of the toilet (we should never use salfumán). Our technicians use the Adinet Cisternas product effective against limescale and does not damage rubber seals.

If we have Vacuflush vacuum toilets We will take into account that an accumulation of mineral deposits may have been generated under the edge of the rubber gasket of the bowl (which makes the system watertight). To clean it, always disconnect both the electricity supply and the water tap. Opening the plastic ball and using a non-abrasive cleaner, such as Sealand Toilet Bowl Cleaner , we will rub under and around the joint. Next we will use a brush and water to clean the loose deposits. Remember not to use products with caustic components, as they can cause irreparable damage to the rubber seals.

Do you use salt or fresh water?

If you use salt water, close the seawater suction valve. To ensure that there is no water leak or flooding due to this cause. Also, never leave traces of salt water inside the pump or cup because it rots, smells bad and creates a layer of lime. Grab one or two buckets of fresh water and pour them into the cup.

If you use fresh water, give the system a few good flushes with water from the supply to completely empty the hoses.

Should we leave the cup dry or with a small amount of water?

If our toilet is electric or manual, it is best to leave it completely dry, without a drop of water inside.

If we have a Vacuflush system, leave two fingers of water, to prevent the joints from drying out and hardening.

For thorough maintenance and wintering:

In manual toilets: dismantle the pump mechanism to clean the rubber gaskets and leave them soaked with a little Vaseline before reassembling them.

In electric toilets: try to dismantle the motor, remove the turbine closing cover, which is made of rubber, and clean the entire part that is in contact with the fresh/salt water, including the delivery pipe.

In Vacuflush vacuum systems, we will only ensure that it is clean and without residue inside, performing several rinses, and following the same procedure as in the hose circuit.

Hose circuit : during the rest period in which the toilet will remain, bacteria can proliferate in the bowl, pipes and storage tank. To inhibit them and disinfect the system, we recommend pouring ½ liter of a specific deodorant and cleaner for black water directly into the toilet, such as Adinet WC nautic . We run the liquid, with water, in the system by flushing the toilet, in this way we will impregnate the hoses of the discharge line and the product will be responsible for cleaning the remains of paper and waste, leaving everything in its path disinfected. and odor-free (avoid using products that contain Formaldehyde, they are very polluting).

Level sensors:

We will access the sensors, clean them of debris and wash them with descaler.

Storage tank:

We will empty the tank, it may be obvious but it is something that is often forgotten and it is not pleasant to return to the boat after a long winter and find it full of disgusting odors coming from the wastewater tank.

We will avoid this trauma by thoroughly cleaning the sanitation system with preferably fresh water, and ensuring its complete drainage, below the waterline, before turning off the water supply.

During winter storage we must check that all clamps and joints are correctly tightened, to prevent any possible leak. And we will ensure that all cable connections are correct when installing the vacuum pump.
