How to Winterize Your Plumbing for a Kamloops Winter

Kamloops winters are not Vancouver winters. We get hard freezes, cold snaps that can drop below minus fifteen overnight, and dry air that pulls moisture out of everything. If your plumbing is not ready for it, you will find out the hard way. This is what to do before the first cold snap hits.

Insulate exposed pipes in unheated spaces

Look anywhere that water lines run through unheated parts of the house. Crawl spaces, attached garages, the underside of cantilevered floor sections, and any pipe near an exterior wall vent. These are the spots that freeze first because warm air from the house never reaches them.

Foam pipe insulation costs about three dollars per six-foot length at any hardware store in Kamloops. Slide it over the pipe, tape the seam, done. For pipes near vents or air gaps, wrap heat tape over the insulation. It is a one-evening job that prevents a four-figure repair bill.

Drain and shut off outdoor faucets

Hose bibs are the most common winter failure point in Kamloops homes. Water trapped in the pipe between the shutoff valve and the outdoor faucet freezes, expands, and cracks the pipe inside the wall. You usually do not notice until spring when you turn the water back on and water starts flowing into your basement. Our spring plumbing checklist opens with the bib pressurization walk that catches a split before drywall opens.

Find the indoor shutoff valve for each outdoor faucet. Close it. Then go outside and open the outdoor faucet to let any remaining water drain out. Leave the outdoor valve open through the winter. If you have frost-free hose bibs you still need to disconnect the hose, otherwise water sits in the bib and freezes.

Check your water heater before you need it

Cold incoming water makes your water heater work harder all winter. If the tank is already showing its age (over ten years, sediment noises, small puddles around the base), winter is when it will quit. Replace it on your timeline in October, not at midnight on Christmas Eve. The full October plumbing checklist catches a tired tank weeks before it dies.

Quick health check: drain a couple of gallons from the bottom valve into a bucket. If the water comes out cloudy or with grit, your tank has sediment buildup from Kamloops hard water. Flushing it (or having a plumber flush it) extends the tank life by years.

Know where your main shutoff valve is

If a pipe bursts at three in the morning, you do not have time to figure out where the main shutoff is. Find it now. In most Kamloops homes it is on the wall where the water line enters the house, usually in the basement near the front of the house. Older homes sometimes have it in a crawl space.

Test that the valve actually closes all the way. Old gate valves seize up from sitting unused for years. If it does not close cleanly, replace it before winter. A ball valve is a fifteen-minute swap and it will work the next time you actually need it.

When the deep cold hits

If the forecast shows a cold snap coming, open cabinet doors under sinks on exterior walls so warm air can reach the pipes. Let one cold-water tap drip slowly overnight on the coldest sides of the house. Moving water freezes much slower than still water.

If a pipe does freeze, do not use an open flame to thaw it. A hair dryer or heat tape works fine and will not set the wall on fire. Start at the faucet end and work backward toward the frozen section so the melted water has somewhere to go.
