Waste water tank system
• Arrange the tanks, and thus the weight, evenly over the ship.
• Install the tank so that it is easily accessible for inspection.
• Also ensure that there is sufficient free space over the top of the
tank for the hose connections. These must be easily accessible
during installation. The tank should be 1 cm (3/8") free all round
from bulkheads or other tanks, to provide ventilation.
Fitting in sailing ships
When fitting remember that the suction waste water hose must al-
ways be positioned on the same side of the ship as the tank.
This prevents too high a pressure from possibly occurring in the tank
when sailing at an angle.
• Ensure that there is a sufficiently solid foundation for placing and
fixing the tank firmly.
• The size of the tank increases slightly when it is full
Take this
into account when fixing the tank in place.
• Attach the tank using the stainless steel rings supplied.
2 2 Tank fittings
The inspection cover and the fittings are pre-assembled in the upper
section of the tank.
• Use the tool provided to fit the fittings in the correct direction.
• If required create additional holes on the top of the tank for extra
fittings (43 mm (1 11/16") dia.).
Choose the position of the fittings so that when the ship is
beached on its side, waste water cannot run back to the toilet, or
flow outside via the tank air-relief.
• Clean saw dust and drill shavings from inside the tank.
Option: Vacuum operated vent valve VRF56A
In the top of the tank, drill the hole for the vent valve (ø 57 mm
(2 1/4" dia.)).

Assemble fittings
• Assemble the fittings with the gasket rings supplied. Tighten the
nuts using the wrench, never with water pump pliers. Do not
tighten the nuts excessively.
• After 2 days check that the connector nuts are still tight, tighten
more securely if required. Repeat this after 4 days.
To prevent blockages caused by hairs and coarse waste in particu-
lar, all fittings should have burrs removed internally, local narrowing
should be reduced to a minimum and any changes in pipe diameter
should be done using conical adapters or large radii.
The sensor for a dirty water level meter is already fitted in the top of
the tank. The sensor can be connected only to a Vetus level indicator
for waste water.
