Waste water tank system
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.
Specially for black water tanks, odour-proof waste water hose:
Article Code: SAHOSE16, 16 mm (5/8”) internal diameter
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.
Attach the discharge connection ‘5’ to waste water pump ‘9’
To assemble the valve correctly, consult the waste water pump man-
ual.
Install hull outlet with valve ‘11’
Install the suction hose ‘17’
(38 mm. dia. (1 1∕2”)) such that neither
the tank, pump or deck cap are subject to any mechanical loads.
If the suction connector ‘3’ is not being used, close the suction pipe
off with a plug.
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.
It is very advisable to fit a smell filter '15' type NSF in the pipe. This
prevents unpleasant smells from the vent nipple.
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.
Install a bend ventilator ‘10’
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.
Rinsing pipe '20'
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.
2 4 Check
Check the system for any leaks.
Extraction pressure 20 kPa (0.2 bar, 3 psi).
