*Turning on the water pump not only draws water from the fresh water tank for use in the RV fixtures, but it also enables pumping into the water
system via a hose attached to the suction inlet. This can be used for pulling in fresh water from a container using the "Tank Fill" settings (for when
pressurized water is not available to fill from the fresh water connection), pulling RV antifreeze in the plumbing lines using the "Winterize" setting,
or for pulling an anti-bacterial solution into the system for line and tank cleanings us the "Tank Fill" setting.
