An optional pump may be installed to pump material through a wand and spray bar. The
pump may be driven by a gas or diesel engine, or by an electrical or hydraulic system. The
plumbing must be purged of material when finished to prevent plumbing freeze-up. This is
done by reversing the pump to suck the material out of the system. An optional flush tank
may also be installed to further flush the system of any remaining material.
