Pipes & water supply

Outdoor pipe burst from freezing

A frozen and burst outdoor line, often for a hose bib or irrigation feed, needs the water shut off promptly and the damaged section replaced before spring use.

Symptoms

  • Water spraying or pooling near an outdoor spigot or irrigation line when first used after a freeze
  • Spigot or pipe visibly cracked or split
  • No water at outdoor fixtures at all
  • Ice damage evident from the prior cold snap

Likely causes

  • CommonStandard (non-frost-free) hose bib left with water in the line over winterWater trapped in the pipe froze, expanded, and cracked the fixture or nearby pipe.
  • CommonHose left attached to a spigot during freezing weatherA connected hose prevents a frost-free spigot from draining properly, causing it to freeze and crack despite its design.
  • PossibleIrrigation system not properly winterizedSprinkler lines not blown out or drained before winter can freeze and crack underground or at valve boxes.
  • Less commonShallow buried pipe below the frost linePipe installed too shallow can freeze even when properly drained, if the layout traps water.

What to do

  1. Shut off the water supply to that outdoor line at its interior shutoff valve as soon as damage is discovered.
  2. Inspect the spigot or pipe closely to find the crack or split.
  3. For a simple hose bib, unscrew and replace the entire unit, which is usually straightforward if accessible from inside.
  4. For irrigation lines, locate the cracked section (often near a valve box) and cut out and replace it with matching pipe and fittings.
  5. Before restoring full water, test the repair briefly and check nearby areas for any additional cracks from the same freeze event.
  6. Disconnect all hoses before the next freeze and install an interior shutoff with drain if the exterior spigot isn't already frost-free.
  7. For irrigation systems, plan to properly winterize (drain or blow out lines) before the next cold season.

Tools and parts

  • Pipe cutter or wrench

When to call a pro

Call a plumber or irrigation specialist for buried line repairs or if the crack extends into pipe you can't access easily.
