A faucet runs slowly, or not at all, on a cold morning

  1. Find which fixtures are affected

    If only one sink or one bathroom has no water, the frozen section is probably in the wall or space that serves it.

  2. Locate your main shutoff

    Know exactly where it is, and that it turns, before you start thawing. A split pipe leaks the moment the ice melts.

  3. Open the affected faucet

    A slightly open faucet lets melting water and pressure escape, and it tells you when flow returns.

  4. Warm the area gently

    Open the cabinet doors, warm the room and apply gentle heat to the pipe you can reach, starting nearest the faucet and working back.

  5. Watch for leaks as flow returns

    Check under the sink, the wall behind it and the room below. A split often shows itself within minutes of thawing.

  6. Call a plumber if you can't reach it

    If the frozen section sits inside a closed wall, or you see a bulging pipe, let a plumber handle the thaw.

Why some Lakewood houses freeze more easily

Post-war ranches often put kitchen and bathroom plumbing on outside walls with modest insulation by today's standards. Bathrooms over an attached garage, laundry rooms on a slab at the edge of the house and hose bibs on the north side are the classic trouble spots. In a split-level, the lowest level may have pipes running through a crawlspace that vents to the outside.

Front Range weather adds a twist. A sunny afternoon can drop into a hard freeze overnight, and arctic air can sit on the metro for days. Pipes that were fine for years can freeze in an unusually cold stretch, especially if someone left a window cracked or the garage door open, or turned the heat down while the house sat empty.

Common weak spots and simple protection

LocationWhy it freezesProtection to discuss with a plumber
Hose bib on a north wallCold air reaches the valve and the short pipe inside the wallDisconnect hoses in fall; consider a frost-free sillcock
Kitchen sink on an exterior wallThin wall insulation behind the cabinetOpen the cabinet doors in a cold snap; add insulation if the wall gets opened
Bathroom over a garageGarage air runs close to outdoor temperatureKeep the garage door closed; insulate the garage ceiling
Crawlspace supply linesVents let in freezing airPipe insulation, and closing vents in winter where appropriate
Swamp cooler supply tubeRuns through an unheated atticDrain it and shut it off before the first hard freeze

Before you leave the house in winter

  • Keep the thermostat at a reasonable setting, not off.
  • Disconnect garden hoses and close the indoor valves to outdoor faucets.
  • Ask a neighbor to check the house if you'll be gone during a cold stretch.
  • For long trips, consider shutting off the main and draining the lines.
  • Consider a water leak sensor near the fixtures most likely to freeze.
