Water Supply - Vetus TMWQ 12 V Manuel D'installation Et D'utilisation

4.3 Water supply

• Fit a ball valve with 3/4" external connection to the water supply
and make sure that this will always be accessible (for water inlet
hose B) or a 13 mm hose connection (connect this to hose con-
nection A using a 13 mm water hose).
If there is already a pressurised water system on board the supply
hose can be connected to this system. The pressure must be at least
1.5 bar; (21 psi) this is the minimum pressure required to allow the
toilet to function properly.
If the water pressure system is less than 1.5 bar (21 psi) or if raw water
is to be used then a supply pump with capacity of at least 10 litres/
minute (2.2 Imp.Gal/min; 2.7 US Gal/min) must be fitted in the water
supply pipe.
If raw water is to be used this must be properly filtered.
An external water pump can be connected as an option. Use the yel-
low and green connection wires.
• Connect the flexible water supply hose to the ball valve on the
water supply.
4.4 Prevention of siphoning
If the toilet is below or less than 50 cm(20") above the waterline there
is a danger of water siphoning back into the toilet (supply pipe). An
air vent must be fitted at the highest point in the supply pipe in order
to prevent siphoning (see the installation example 1B, see page 38).

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.
