Quick Answer: To winterize your entire water system, insulate all exposed pipes and tanks, drain outdoor lines, protect your well head with an insulated cover, and add non-toxic antifreeze where safe. Shut off the main water supply for vacant properties and open faucets to relieve pressure. Use heat tape on critical components and check local frost depth guidelines to bury pipes deep enough. A sudden drop in temperature can turn a reliable off-grid water system into a costly nightmare. Water expands by about 9% when it freezes, and that expansion can generate pressure over 2,000 pounds per square inch inside a pipe or tank. No material in a typical home water system can withstand that force. Frozen pipes burst, well pumps crack, and storage tanks split, leaving you without water when you need it most. Repair bills from freeze damage average $4,000 to $8,000 according to industry estimates, and secondary water damage can double that figure. ...
