Eric Aune, a licensed master plumber with nearly 30 years of experience, breaks down why outdoor hose faucets are so vulnerable to freezing — and what homeowners can do about it. He walks through the difference between standard hose bibs and frost-free faucets, explaining how each handles water pressure and where failure points typically occur. The real focus is on isolation valves with built-in drains, which allow the water supply to an outdoor faucet to be shut off and the line fully drained before winter hits. Eric covers several valve styles, from basic sweat ball valves to hose-connection drain valves used in professional installs.
