How to keep pipes and sprinklers from freezing in an Ogden winter

Most freeze damage around Ogden starts with the same few pipes. Here is how to protect them in the fall and what to do in a cold snap.

In the fall, before the first hard freeze

Disconnect every garden hose

This is the single most common cause of freeze damage we hear about. Most Utah homes have frost-free spigots, which keep the valve inside the warm house and drain the pipe when you shut them off. A hose left attached traps water in that pipe. It freezes and splits inside the wall, and nobody knows until the spigot gets turned on in spring and water pours into the basement ceiling.

Blow out the sprinkler system

Once irrigation water shuts off in the fall, have the lines blown out with compressed air, or do it yourself if you know how. Pay attention to the backflow preventer, usually near the foundation, and any valves close to the house. Those are the parts that crack and leak toward the basement.

Insulate exposed pipes

Foam sleeves are cheap and quick. Put them on pipes in the garage, crawlspace, unfinished basement walls and anywhere a pipe runs along an outside wall.

Seal the drafts

Cold air through gaps at the rim joist, around pipe and wire holes, and at dryer vents is enough to freeze a nearby line. Spray foam and caulk fix most of it.

Find your main water shutoff

Make sure it turns, and show everyone in the house where it is.

During a cold snap

  • Keep the thermostat at the same temperature day and night.
  • Open cabinet doors under sinks on outside walls so warm air reaches the pipes.
  • Let faucets on outside walls drip slowly overnight. Moving water is less likely to freeze.
  • Keep the garage door closed if pipes or a water heater are out there.
  • If you leave town, keep the heat at 55 degrees or higher and ask someone to check the house. For longer trips, shut off the main water and drain the lines by opening the lowest faucet.

Cabins and second homes

Cabins up Ogden Canyon, in Eden and around Pineview have the most to lose, because a furnace failure can go unnoticed for weeks. Either keep the heat on with a remote temperature alert or fully winterize the plumbing: shut off the water, drain the lines and water heater, and put RV antifreeze in the traps. A leak detector with a phone alert costs far less than the cleanup.

If a pipe freezes

You will usually notice a faucet that only trickles or does not run at all.

  1. Keep that faucet open.
  2. Warm the pipe with a hair dryer, a space heater kept at a safe distance, or warm towels. Never use an open flame.
  3. Start near the faucet and work back toward the frozen section.
  4. If you cannot reach the frozen section, or you suspect it already split, shut off the main water and call a plumber.

If a pipe bursts

Shut off the main water right away, open a faucet on the lowest floor to drain the lines, turn off power to wet rooms if it is safe, and call. Water from a burst pipe gets into ceilings and walls quickly, and those areas need to be opened and dried. Call us and we will connect you with a local company that can start the same day.

Common questions

Do I need to drain my water heater for the winter?

Not if the house stays heated. Only drain it if you are shutting the house down for the winter, like a cabin. Flushing the sediment out once a year is a good idea in hard-water areas, and that is a separate job.

When should I blow out my sprinklers?

After irrigation water shuts off for the season and before the first hard freeze, which is usually in October around Ogden. Check with your water provider for the shutoff date.
