The drain pipe should be firmly
attached to the standpipe or the
laundry tub or sink where it drains.
The pump has sufficient power to
cause the pipe to move around
when the water is expelled. The
pump can lift the drain water a
maximum of 96 inches (2.4 m),
but there is no minimum height
requirement. The vacuum breaker
in the drain line will prevent
drainage by gravity or siphoning.
The hose can lay flat into a floor
drain as long as the end of it is
not submerged.
