Blow the water lines clear and pour a little antifreeze in the drain traps. No problem, I do it probably 6 or 7 times a winter between my 2 m/hโs.
Just be sure to read up on how to *properly* blow the lines clear.
No sanitizing required because youโre not filling the lines with goop, once you get the hang of it, winter ing takes 10 minutes, and getting ready for use takes less than 5 minutes. Hook up water and open taps.
