Our house was designed for quick winterization. No need to use a compressor. The hot and cold water pipes are sloped to central feeders in the basement with purge valves. To winterize, I close the main water valve, open the purge valves and open all faucets, flush toilets until tanks are completely emptied. I then add RV antifreeze to all traps and toilets. 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.
