2 3 Tank connections
Connect the tank with a good quality reinforced hose. Avoid sharp
bends and kinks or sagging in the hose.
Bracket the hose at not too far apart, regular points, to prevent the
hose sagging. Deposits will collect in these sags, causing a blockage
after time.
The reinforced hose should be an odour-proof waste water hose
and resistant to a limited under- and over-pressure of 30 kPa (0,3
bar, 4 psi).
Vetus supplies a hose suitable for waste water.
Article Code: WWHOSE19A, 19 mm (3/4") internal diameter
WWHOSE25A, 25 mm (1") internal diameter
WWHOSE38A, 38 mm (1 1/2") internal diameter
Specially for black water tanks, odour-proof waste water hose:
Article Code: SAHOSE19, 19 mm (3/4") internal diameter
SAHOSE25, 25 mm (1") internal diameter
SAHOSE38, 38 mm (1 1/2") internal diameter
Fit every hose connection with a good stainless steel hose clip.
Install pump '10' and hull outlet with valve '12'
Install the suction hose(s) '17' (ø 38 mm, 1 1/2" dia.) such that neither
the tank, pump or deck cap are subject to any mechanical loads.
Fit the air-relief nipple '14' as high up as possible above the level of
the top of the tank. Choose a place for the nipple where rain or other
outside water cannot enter.

Riged waste water tanks 25 l
Fit the air-relief pipe '18' , internal diameter 19 mm (3/4") between
the air-relief nipple and the tank. When viewed from the tank, the
air-relief pipe should run straight upwards.
It is very advisable to fit a smell filter '15' type NSF in the pipe. This
prevents unpleasant smells from the vent nipple.
Rinsing pipe '21'
In order to rinse out the tank easily with clean water, and extra fitting
can be made in the deck connected to an extra deck cap. Clean water
can be poured in through this pipe.
Discharge pump
A non-priming waste water pump must be fitted lower than, or at
the same height as the underside of the tank. The connection for the
pump in the tank must therefore be as low as possible in the tank.
A self-priming pump can be mounted at any height in relation to the
tank.
Install an air vent '11' in the discharge pipe between pump and hull
outlet when the waste water tank is below the water line and the hull
outlet is also below the water line.
