Winterize Plumbing: BC Home Guide

How to Winterize Your Plumbing in Surrey, Richmond, Delta, Langley, or anywhere in the Lower Mainland

Although we seem to get away with mild winters in Southern British Columbia, they can still be unpredictable. One cold snap can cause unprotected pipes to freeze and burst, leading to expensive water damage and urgent repairs. At Acorn, we help homeowners in prepare their plumbing for winter the safe, environmentally responsible way.

Why Winterizing Matters

Even mild Vancouver winters can produce freezing nights. When water freezes, it expands, creating pressure that can crack pipes, fittings, or valves. Burst pipes can mean flooded basements, damaged walls, and disrupted heating systems. The good news? A few straightforward steps now can prevent costly problems later.

Step 1: Insulate Vulnerable Pipes

Pipes in unheated or poorly insulated areas – garages, crawlspaces, exterior walls, or under sinks near outside walls, are most at risk. Use foam pipe sleeves or fiberglass insulation to keep them warm. Heat tape can come in handy in hard-to-reach places as well. Pay special attention to elbows and joints, where heat loss is greatest.

Step 2: Shut Off and Drain Outdoor Faucets

Before the first freeze:

  • Close the interior shut-off valves supplying outdoor taps.
  • Disconnect and store garden hoses out of the elements.
  • Open outdoor faucets to drain any remaining water.

This prevents water from sitting in pipes where it can freeze and expand.

Step 3: Seal Cold Air Entry Points

Cold drafts can quickly lower temperatures around pipes. Inspect for gaps or cracks where plumbing enters walls or foundations. Seal openings with caulking or expanding foam. Check basement windows, crawlspace vents, and garage doors for weatherstripping or insulation needs.

Step 4: Keep Water Moving on the Coldest Nights

On especially frigid nights, allow a small trickle of cold water to run from a tap connected to vulnerable pipes. Moving water is less likely to freeze. You can also open cabinet doors under sinks to help warm household air circulate around the pipes.

Step 5: Maintain Steady Indoor Heat

If you’re away for a weekend or extended trip, keep your thermostat set to at least 15 °C. A consistent indoor temperature prevents unexpected freeze-ups while you’re gone.

What to Do if a Pipe Freezes

If you notice reduced water flow or see frost on pipes:

  1. Turn off the main water supply.
  2. Gently warm the affected pipe with a hair dryer or space heater. Never use an open flame.
  3. Once water is flowing, check for leaks and contact Acorn Service Group

Prompt action can minimize water damage and repair costs.
