draining the water and pumping a permanent-type
automobile anti-freeze containing a rust inhibitor
through the system. A 50% mixture with water is
recommended. Be sure to flush the system with a
neutralizing liquid prior to re-use of the Pump.
WARNING! The oil inside some pump types
can be harmful to the environment. Check state
environmental laws before disposing of any pump oil.
