How to Winterize Outdoor Faucets & Hose Bibs

A hose left on through the first freeze is one of the most common ways a Southern Indiana home ends up with water inside a wall. Ten minutes in the fall prevents it.

When water in an outdoor faucet freezes, it expands and can split the pipe or the faucet, sometimes inside the wall where you won't see it until it thaws and floods. Preventing it is one of the easiest, highest-value fall chores there is.

The fall routine

  1. Disconnect every hose. This is the single most important step. A hose left attached traps water against the faucet, and that trapped water freezes and backs up into the pipe. Drain the hoses and store them.
  2. Know which faucets you have. Newer "frost-free" hose bibs are built to drain themselves when the hose is off and the faucet is closed, but only if they're pitched right and the hose is disconnected. Older standard faucets need you to shut off and drain them.
  3. Shut off the indoor valve, if there is one. Many homes have a shutoff on the pipe feeding each outdoor faucet, usually just inside the wall in a basement or crawlspace. Close it.
  4. Open the outdoor faucet to drain it. With the supply off, open the outside faucet and let the water in the line drain out. Leave it open through winter, if there's a bleeder cap on the indoor valve, open that to let the last water out.
  5. Add an insulated cover. A foam faucet cover (a few dollars) over each outdoor faucet adds cheap insurance against a hard freeze.

Also on the freeze list: drain and blow out irrigation/sprinkler systems before the first hard freeze, and don't forget a faucet on a detached garage or barn. Any exposed pipe in an unheated space is a candidate to freeze.

If a pipe does freeze

If an outdoor faucet or an exposed pipe freezes, close the nearest shutoff and let it thaw slowly, never with an open flame. Watch closely as it thaws, because a split pipe only reveals its leak once the ice melts. If you see or suspect a burst, shut the water and call.

Know when to call a pro

The fall routine is simple DIY. Call a plumber when you have no shutoff for an outdoor faucet and want one added, when a faucet drips or leaks even after draining, when a pipe has already burst or you find water inside after a freeze, or when you want exposed pipes in a crawlspace properly insulated or heat-taped. A burst supply line inside a wall is a fast-damage situation, better to prevent or catch early.

No outdoor shutoff, or a pipe already burst?

A burst line floods fast. Shut off your main and let us get a licensed plumber on it, or add the shutoff before next winter.
