Introduction

These instructions apply for the connection kit for the Vetus rigid
plastic waste water tanks for grey water and black water.
When installing a waste water tank, the European Recreational Craft
Directive (RCD, 2013/53/EU) and any national legislation must be ob-
served. Use the ISO 8099 standard as a guide.
Grey water tank
- A grey water tank should only be used for collecting water from
the sink, shower, wash basin, air conditioning, etc..
- The capacity of a waste water tank can never be too large.
- Match the capacity to the amount of fresh water available; the
capacity of the water tank(s).
- Fit sink, shower, wash basin, etc. with a drain with sieve, so that
coarse waste, such as hair etc., will be less likely to enter the grey
water tank.
Black water tank
- A black water tank is used only for temporary collecting toilet
waste.
- The capacity of a waste water tank can never be too great.
- The capacity should be calculated using the amount of flushing
water (outside water) used by the toilet. Reckon on 7 to 14 litres
(1.5 to 3 Imp. Gal., 1.9 to 3.8 US Gal.) of black water per person
per day.

Installation

General

When choosing a place for the tank and for the deck filler cap, take
the following into account:
- The suction hose should be as short as possible, must go directly
down to the tank and be as straight as possible.
- The space in which the tank is placed should be properly venti-
lated.
Instead of just one grey water tank, it is also possible to distribute the
total capacity required over two or more tanks.
Arrange the tanks, and thus the weight, evenly over the ship.
(F = Fuel, W = Water, WW = Waste Water)
Connection kit for waste water tanks
- Use only water-soluble toilet paper to prevent unnecessary block-
ages. Sanitary towels and tampons in the toilet and black water
tank will certainly cause blockages.
Clearing a blockage is an unpleasant job, make sure you have a pair
of rubber gloves on board.
Smell
Grey water tank
- Unpleasant odours will be produced in every grey water tank. Fit
the sink, shower, wash basin, etc., with an S-bend (siphon or stink
trap) and a plug.
Black water tank
- Unpleasant smells caused by faeces will be produced in every
blackwater tank. The use of sea water for flushing will increase the
smell. The algae in sea water also produce unpleasant smells.
- It is possible to add special additives to waste water tanks to re-
duce the smell, called tank deodorants. A simple way of reducing
the smell is by using washing soda, which cleans and sterilizes.
- Leaking hoses, hose fittings, tanks, tank covers, etc., can also cause
a smell nuisance. So carry out a regular check of the whole system.
For dimensions, see drawing on page 39. Tolerances of +/- 2% apply
to all tank dimensions!
Position the tank in such a way that the plug P is on the top
side of the tank. Consult the diagrams on p. 39 for placement
of plug P.
