Anti freeze is cheap.
Use lots.
Pull hot water tank plug and pressurize to blow out the sediment in the notion of the tank.
Bypass hot water tank. Do not put anti freeze in there.
Use compressed air if you wish.
Disconnect and drain all showers ( inside and out )
Then fill system with antifreeze and run each tap till anti freeze runs out.
Don’t forget low point drains and grey and black tanks.
Dump a cup or two into each trap.
I leave all my valves open.
