should you run water when it's cold

Yes, running a faucet at a slow trickle during extremely cold weather helps prevent pipes from freezing and bursting.

Why It Works

Keeping water moving through pipes—even just a pencil-thin stream—stops it from stagnating and forming ice blockages, as moving water freezes at a lower temperature than still water. Plumbing experts and utilities like the Red Cross recommend this when temps drop below freezing, especially overnight or for exposed pipes. Costs are minimal (pennies per night), far less than repair bills from bursts.

When to Start Dripping

• Turn on the farthest indoor faucet from your water meter (often a bathroom sink) when forecasts hit near 32°F, particularly if pipes are uninsulated or in walls/crawlspaces.

• Do both hot and cold sides, as hot water lines can freeze too—run hot briefly every few hours during the day.

• Outside spigots: Disconnect hoses first, then drip indoor faucets connected to them.

Multiple Perspectives

Utilities say one faucet suffices to minimize waste, but plumbers on forums like Reddit warn that too slow a trickle risks drain freezes—aim for enough flow to hear it steadily. Some debate exact temps (mid-20s°F may need it if you're asleep/away), while others insulate pipes first as a better long-term fix. In milder climates like the South, it's still advised during rare deep freezes.

Extra Precautions

1. Open cabinets under sinks to let indoor heat reach pipes.
2. Insulate exposed lines with foam sleeves.
3. Shut off outdoor water lines if possible.
4. Use a water alarm for flood detection.

Imagine coming home to a geyser from a split pipe—dripping is the simple hero move that averts plumbing nightmares, as countless homeowners have shared in winter horror stories.

TL;DR: Drip faucets (one indoor, slow trickle) below freezing to keep pipes safe—yes, it's worth it.
