WINTERIZING
Winterizing:
•
Improper winter lay up is a major cause of marine
toilet failure.
•

system.
•
Dispose of all antifreeze in accordance with local
and federal regulations.
•
Winterize holding tanks, plumbing, treatment
systems (MSD’s), etc. independently following
manufacturer’s instructions.
