Should I Drip Hot Water During a Freeze?
Dripping hot water during a freeze can help protect an exposed hot-water branch, but it is usually not the best first choice. In most cases, dripping the cold-water faucet, insulating pipes, sealing drafts, and keeping the heat steady are more efficient and reliable. Consider a hot-water drip only when the hot line itself is vulnerable and you need a temporary safeguard.
