10 .5 Winterizing the System – DX
Only
Any winterization method that causes the antifreeze
solution to flow downward is the method of choice. By
this means, the antifreeze solution displaces any trapped
water and eliminates the possibility of it freezing in
hidden areas.
Choose one of the methods below. The first two
methods use a 50/50 nonpolluting biodegradable
antifreeze/water solution:
1. Pump the antifreeze solution into the overboard thru-
hull fitting, and discharge through the intake thru-hull
fitting.
2. Use the seawater pump to pump the antifreeze
solution through the system and discharge through
the overboard thru-hull fitting:
a. Close the seacock.
b. Remove the hose from the strainer discharge.
c. Raise the hose above the pump (so the pump
does not lose its prime) and pour in the antifreeze
solution.
d. Pump the solution through the system.
e. Drain the water from the strainer and the hose to
the seacock.
3. Inject pressurized air at the overboard discharge
fitting to force any system water through the seawater
intake fitting, and expel any trapped water from the
system.
