Closing Up for Winter

I dump a little antifreeze in the toilet tanks to prevent residual water from from freezing.
The hot water heater has its own drain, so I simply turn off the breaker an open the drain spigot.
I fill the dishwasher sump with RV antifreeze then start and cancel a cycle so it drains and fills the trap with antifreeze.

It takes about 15 -20 minutes.

Pretty much the same routine and we are on an island and do it ourselves. Dock is crib so we just put a circulator in. Only springtime plumbing issues we've had are: kitchen sink hose faucet cracked (now I make sure to drain that), and toilet tank fill valves cracked (in tank anti-siphon valves need to be opened up.....four screws and blow water out with a quick puff after lifting the small membrane).
