4.3.2 Water supply

Fit a ball valve with 3/4" external connection to the supply pipe
and make sure that this will always be accessible.
If there is already a pressurised water system on board the sup-
ply hose can be connected to this system. The pressure must
be at least 1.5 bar; this is the minimum pressure required to
allow the toilet to function properly.
If the water pressure system is less than 1.5 bar or if external
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 fit-
ted in the water supply pipe.
If external water is to be used then this must be properly fil-
tered.
The toilet has a 3/4" connector.
Connect the flexible water supply hose to the ball valve on the
water supply pipe.
4.3.3 Preventing siphoning
When the toilet is below, or less than 40 cm. (16") above the
waterline, there is a danger of outside water being siphoned
into the toilet through the outlet. To prevent this siphoning, fit an
air-relief valve in the highest point in the outlet (see Installation
examples).
