As November settles over Vancouver, temperatures begin to dip toward freezing, and homeowners start to think about insulation, gutters, and heating systems. But one critical task often gets overlooked — preparing your outdoor plumbing for winter.
From hose bibs and garden faucets to sprinkler systems and exterior water lines, these fixtures are especially vulnerable to cold snaps. A single night of below-zero temperatures can cause water inside pipes to freeze, expand, and burst — resulting in thousands of dollars in water damage.
This November, follow this comprehensive checklist from Einstein Pros Plumbing Vancouver to ensure your outdoor plumbing is winter-ready and protected from costly freeze damage.
1. Disconnect and Drain All Garden Hoses
Leaving a hose attached to an outdoor faucet is one of the most common mistakes homeowners make in late fall. Even if you’ve turned off the spigot, residual water can remain trapped inside the hose and back up into the faucet and connected pipes. When that trapped water freezes, it expands and can split your pipe or crack the fixture.
How to do it:
- Turn off the water to the outdoor faucet.
- Disconnect the hose from the spigot.
- Drain the hose completely by stretching it out along the ground.
- Coil the hose and store it in a dry, indoor space like a garage or shed.
According to the City of Vancouver’s water system guidelines, homeowners are responsible for protecting private plumbing fixtures from freeze-related damage — so taking this simple step now can prevent an expensive call later.
2. Shut Off and Drain Exterior Hose Bibs
Modern homes often have frost-free hose bibs, but older properties may not. Either way, it’s essential to shut off the water supply to exterior faucets before freezing temperatures arrive.
Step-by-step:
- Locate the interior shutoff valve that controls the outdoor faucet. It’s often in the basement or utility area near the point where the pipe exits the wall.
- Turn the valve to the “off” position.
- Go outside and open the exterior faucet fully. Let all remaining water drain out.
- Leave the faucet open through the winter — this prevents trapped water pressure from building up if any residual moisture freezes.
If your home lacks a dedicated shutoff valve, it’s worth considering installing one. The plumbing professionals at Einstein Pros Vancouver can retrofit your existing lines to include an interior shutoff, helping you save on future repairs.
3. Insulate Exposed Outdoor Pipes
Even properly drained pipes can still be at risk if exposed to wind and cold air. Insulating them is one of the easiest and most cost-effective ways to add freeze protection.
Materials you can use:
- Foam pipe insulation sleeves (available at most hardware stores)
- Fiberglass pipe wrap
- Weatherproof insulation tape
When installing insulation, pay special attention to spigots, elbows, and joints, as these areas tend to freeze first. Be sure to secure insulation tightly and seal any gaps where cold air could enter.
The Government of Canada’s “Get Prepared” program also emphasizes insulation and sealing as key steps in household winter readiness — not just for comfort, but for safety and energy efficiency.
4. Winterize Your Sprinkler System
If you have an irrigation or sprinkler system, it’s crucial to blow out the lines before the first frost. Sprinkler lines sit close to the surface, and trapped water inside can freeze and rupture the pipes or damage sprinkler heads.
How to do it safely:
- Turn off the main water supply to the sprinkler system.
- Manually open drain valves at the low points of the system.
- Use compressed air (typically 50–80 psi) to gently blow out remaining water from each zone.
If you’re not comfortable using compressed air, Einstein Pros can provide professional sprinkler winterization services, ensuring that every line is properly cleared without risk to your pipes or valves.

5. Inspect and Protect Outdoor Faucets
Once drained, it’s a good idea to cover your exterior faucets with insulated covers. These inexpensive foam caps provide an extra layer of protection against frost and wind chill.
Also, inspect the faucet area for leaks or drips — even a small leak can introduce water into the wall cavity, where it can freeze and cause hidden damage. If you notice corrosion or cracking, schedule a quick inspection with Einstein Pros Vancouver, where certified technicians can repair or replace faulty fixtures before winter hits hard.
6. Know the Signs of a Frozen Pipe
Despite best efforts, freezes can still happen — especially during an unexpected cold snap. Recognizing the early signs can help you act quickly:
- Little or no water flow from an outdoor or indoor faucet.
- Unusual sounds when you turn on a tap (banging, whistling).
- Frost or condensation on visible pipes.
If you suspect a frozen pipe, turn off the water supply immediately and open nearby faucets to relieve pressure. Then, gently warm the frozen section with a hair dryer or heating pad. Never use an open flame. If the pipe bursts, shut off the main valve and contact Einstein Pros Emergency Plumbing for immediate assistance.
7. Final November Plumbing Maintenance Tips
- Check your sump pump to ensure it’s operational before the rainy season intensifies.
- Inspect your outdoor drainage and gutters for blockages.
- Schedule a pre-winter plumbing inspection — Einstein Pros offers comprehensive maintenance plans for Vancouver homeowners that include leak detection, pipe insulation checks, and water heater inspections.
Conclusion
A few hours spent winterizing your exterior plumbing this November can prevent thousands in repair costs and protect your home from serious water damage. Vancouver’s mild coastal climate still experiences freezing temperatures, especially at night — and prevention is always cheaper than emergency plumbing.
