A hard freeze can turn a forgotten garden hose into a four-figure plumbing bill. Water left in an outdoor faucet or the pipe behind it expands as it freezes, which can crack the bib, split a pipe in the wall or send water into a crawl space when everything thaws. Winterizing outdoor faucets is one of the highest-value DIY jobs of November, and most homes can finish it in under an hour. This guide covers common hose bibs. If you have a complex irrigation manifold, a pump house or are unsure where the shutoff is, pause and ask a plumber.

What you need

  • The location of your indoor shutoff valves for outdoor faucets (often in the basement, crawl space or utility closet)
  • A bucket or two
  • A towel
  • Foam faucet covers or an old towel plus a plastic bag and tape for insulation
  • Optional: pipe insulation for any exposed outdoor piping
  • Optional: plumber’s tape if a cap needs a fresh seal

Step 1: Disconnect hoses and timers

Unscrew every hose, Y-splitter, vacuum breaker accessory and automatic timer from the faucet. Leaving a hose attached traps water and can also keep a check valve from draining properly. Drain the hoses fully and store them indoors coiled loosely, not kinked.

Step 2: Find and close the indoor shutoff

Follow the pipe from the outdoor faucet back inside. Close the dedicated shutoff valve firmly, but do not force a stuck valve — that is a plumber moment. If your home has frost-free sillcocks, you may still want to shut water off for the season in very cold climates; check your faucet type and local guidance.

Step 3: Open the outdoor faucet and drain

Go outside, open the faucet and let remaining water run out into a bucket. Leave the outdoor faucet open for now so any leftover water has somewhere to go if temperatures bounce. Inside, if there is a small drain/bleed cap on the shutoff assembly, open it over a towel and catch drips until air comes through.

Step 4: Cap and insulate

Some homeowners install a threaded cap on the outdoor outlet for the winter; others simply cover the faucet. Foam faucet “socks” are inexpensive and effective when they fit snugly. In a pinch, wrap the faucet with a towel, cover with a plastic bag and tape it closed so wind cannot strip the insulation. Insulate any exposed pipes on the exterior wall as well.

Step 5: Label what you did

Put a piece of tape on the indoor shutoff that says “OUTDOOR FAUCET — CLOSED FOR WINTER” and the date. Future you, or a house sitter, will not accidentally open it during a January thaw without also checking the outdoor side.

Special cases to respect

  • Frost-free faucets: These are designed to shut water off deeper in the warm wall, but they still fail if a hose is left attached. Always remove hoses.
  • Irrigation systems: Sprinkler blowouts are a different job, often needing an air compressor and zones knowledge. Do not assume faucet winterizing covers the yard system.
  • Shared meters / apartments: Confirm what you are allowed to shut off before closing valves.

A quick annual calendar

  1. Early November: disconnect hoses and test shutoffs.
  2. Before the first hard freeze forecast: drain and insulate.
  3. Midwinter thaw: glance for drips at the indoor shutoff.
  4. Spring: remove covers, open shutoffs slowly and check for leaks before reconnecting hoses.

The bottom line

Winterizing outdoor faucets is unglamorous and extremely worth it. Disconnect, shut off, drain, insulate and label. Spend thirty minutes now, and you are far less likely to spend a holiday weekend dealing with a split pipe.
