WARNING
WARNING

Macerator Pump Winterizing

Plan your winterizing and storage ahead, and be sure
the holding tanks are drained and flushed thoroughly.
This is very important, as the frozen sewage and water
could seriously damage the system� After dumping the
tanks, add a quart or two of RV, non-toxic antifreeze to
one of the holding tanks and start the macerator pump�
Run the pump until the RV, non-toxic antifreeze comes
out the end of the pump hose� Leave dump valves
open� As extra protection, open the toilet valve and add
a quart of RV, non-toxic antifreeze to the Black Water
tank and pour a quart of RV, non-toxic antifreeze into
a sink drain to protect the holding tanks, valves, and
pump from residual water freezing�
