Tom:
My system is pretty simple, however, I use approx. +3 gallons of
plumbers antifreeze.....I find it on sale for about $5 gal......I always
buy 4 gals. and use most of it.
I empty the tank by turning on a tap in the galley and maybe one in the
head. I then climb into the port lazarette to access the hot water tank
and open the bottom drain to empty the tank which flows into the
bilge.....fresh water tank and hot water tank should now be empty. Then
empty the bilge of any water.
I then pour approx 2 gallons of plumbers antifreeze (PA) into the water
tank and first turn on the cold water tap(s) in the galley and
head....one at a time until the PA flows from the tap....I then repeat
with the hot water taps until I see PA flowing from the tap.
Pour PA into the bilge, activate the electric pump until you see PA
exiting the hull. Next I go into the cockpit and pump the manual pump
until I see PA exiting the thru hull.
There is a shower pump in the head so I pour some PA into the sump, turn
on the pump until I see PA exiting the outlet.
I use regular concentrated antifreeze in my engine and what it does not
need, I pour it into the head with the remaining PA and pump the head
until there is antifreeze exiting the thru hull.
Because of the angle my boat sits on its cradle and the side of the
fresh water tank where the water exits, there is approx. 1 quart of PA
in the far end of the tank which will sit all winter if I don't remove
it, which I do with a small hand pump.
My boat came from Racine, Wisconsin and this is how the original owner
winterized the fresh water system so I did the same. Been doing this
for 12 winters now with no issues and do not have to disassemble any of
the plumbing system.

What's the best practice for Winterizing the fresh water system?
My system:
40 gallon tank estimated
Water heater
Pressurized water pump
2 fixtures hot / cold from the pump
1 fixture in the galley from a foot pump.
My boat is on Lake Superior northern WI. And no I cannot sail it to
warmer climate for the winter.
