Kamloops may be semi-arid, but winter temperatures routinely drop to -15°C and occasionally below -25°C. When that happens, unprotected water pipes freeze. And when water freezes, it expands — with enough force to split copper, PEX, and even cast iron. A single burst pipe can dump hundreds of gallons into your home before you even realize it.
The pipes most at risk are in unheated or poorly heated areas: crawl spaces, attics, garages, exterior walls, and basements with minimal insulation. Homes on piers or with vented crawl spaces in Barnhartvale, Dallas, and rural areas are especially vulnerable because cold air circulates freely beneath the floor.
Pipe insulation is the first line of defense. Foam pipe sleeves cost $2 to $5 per foot and can be installed by any homeowner. Focus on exposed pipes in unheated areas first — the main supply line where it enters the crawl space, pipes under kitchen and bathroom sinks on exterior walls, and any pipe running through the garage.
Heat tape — also called heat cable — is essential for pipes that cannot be adequately insulated. Self-regulating heat tape wraps around the pipe and maintains a temperature just above freezing. It is particularly effective for well lines, pressure tank connections, and outdoor hose bibs. A GFCI-protected outlet is required for safe installation.
Sealing air leaks around plumbing penetrations stops the cold drafts that accelerate freezing. Check where pipes pass through exterior walls, rim joists, and foundation openings. Spray foam or caulk around these gaps blocks the wind that makes freezing more likely.
Keep cabinet doors open under sinks during extreme cold. The warm air from your heated living space circulates around the pipes, raising their temperature by several degrees. It is a zero-cost fix that prevents countless freeze-ups every winter.
Let faucets drip during prolonged cold snaps. Moving water is harder to freeze than standing water. A slow drip — roughly one drop per second — keeps water circulating through vulnerable sections. Focus on the faucet farthest from the water meter to ensure flow through the entire line.
Maintain a minimum thermostat temperature of 16°C, even when you are away. Turning the heat off to save money while on vacation is the single most common cause of catastrophic freeze damage we see. The $50 you save on heating is not worth $15,000 in water damage.
If a pipe does freeze, shut off the main water valve immediately. This limits the volume of water that can escape when the pipe thaws. Then apply gentle heat — a hair dryer, heating pad, or warm towel — starting at the faucet and working backward toward the frozen section. Never use an open flame or propane torch. If you cannot locate the freeze or restore flow, call a plumber before the pipe splits.
For seasonal properties or cabins, winterization is the only reliable approach. A licensed plumber can drain the entire system, blow out remaining water with compressed air, add RV antifreeze to traps and toilets, and shut off the main supply. This eliminates any risk of freeze damage while the property is vacant.
Alongside regular home upkeep, consulting a professional Plumbing Kamloops service can help keep your home systems running efficiently and prevent small issues from becoming costly repairs.
