Notes and installation diagram.
For waste water from the shower and bath, ensure that the slope of the
siphon is
at least 1% (0.4 inch per 40 inch), so that the waste water flows through the natural
gravity to the unit position.
If other sanitary units are connected to the disposal line along the disposal circuit,
install check valves in the appropriate waste pipes to prevent back flow.
The slope of the horizontal components must be at least 1%.
Note: Discharge pipe length to the first elbow should be a minimum length of 1.6
feet (0.5m).
