The short answer
Shut off and Drain Outdoor Faucets
Start by locating the shutoff valve for each outdoor faucet, usually inside the home near the point where the pipe exits. Turn the valve clockwise to stop water flow. Then open the outdoor faucet to let remaining water drain out. Leave the faucet open during winter so any trapped water can expand without pressure building up.
If your faucet has a bleeder cap, remove it to let water escape from the pipe. Some homes have frost-proof faucets, but these can still fail if a hose is left attached. Always disconnect garden hoses and store them indoors. A hose left connected can trap water and freeze back into the pipe, causing a burst.
Insulate Exposed Pipes
Pipes that run along exterior walls, in crawl spaces, or under porches are most at risk. Wrap them with foam pipe insulation or heat tape. Pay special attention to elbows and joints where freezing often starts. Insulation slows heat loss, but it does not add heat, so it works well when combined with draining.
Check for gaps around pipe entry points and seal them with caulk or spray foam. Cold air can sneak in through small openings and chill the pipes. For extra protection, use pipe sleeves made of fiberglass or polyethylene. These are easy to cut and fit around most standard pipe sizes.
- Disconnect and drain all garden hoses
- Close inside shutoff valves for outdoor faucets
- Open outdoor faucets to drain remaining water
- Wrap exposed pipes with foam insulation
- Seal gaps around pipe entry points
- Consider installing faucet covers for extra protection
Protect Sprinkler and Irrigation Systems
Sprinkler systems hold water in underground lines and backflow preventers. If that water freezes, it can crack the pipes and valves. You need to drain the system completely. Many systems have manual drain valves at low points; open them and let the water run out. Some have automatic drains that open when pressure drops.
For systems without drains, you may need to blow out the lines with compressed air. This is a job that requires the right equipment and safety care. If you are not comfortable doing it, hire a local water damage pro or a sprinkler specialist. After draining, close the main valve and insulate the backflow preventer.
Handle Pool and Outdoor Kitchen Plumbing
Pool pumps, filters, and heaters contain water that can freeze and crack. Lower the water level below the skimmer and drain the pump and filter. Store removable parts like hoses and valves indoors. Follow the manufacturer instructions for your specific pool equipment, since steps vary by model.
Outdoor kitchens often have a sink, refrigerator line, or ice maker. Shut off the water supply to these fixtures and drain the lines. Open the faucet to let air in and water out. For refrigerator lines, disconnect and drain the tubing. Cover any exposed fittings with insulation to keep them from freezing.
Prepare for Unexpected Freezes
Even with winterizing, a sudden deep freeze can catch you off guard. Keep cabinet doors under sinks open to let warm air reach pipes. Let a faucet drip slightly during extreme cold; moving water is less likely to freeze. Know where your main water shutoff valve is so you can stop the flow quickly if a pipe bursts.
If a pipe does freeze, open the faucet and apply gentle heat with a hair dryer or warm towels. Never use an open flame. If you cannot thaw it or you see cracks, turn off the water and call a local water damage pro. They can assess the damage and help with cleanup and repairs. Acting quickly can reduce the extent of water damage.
- Know your main water shutoff valve location
- Let faucets drip during extreme cold
- Open cabinet doors to warm pipes
- Use a hair dryer to thaw frozen pipes slowly
- Never use a torch or open flame
- Call a pro if you suspect a burst

Do I need to winterize outdoor plumbing if I live in a warm climate?
Even in warm climates, a rare cold front can bring freezing temperatures for a few hours. Pipes in unheated areas like garages or crawl spaces can still freeze. A simple drain and insulation routine takes little time and can prevent a costly burst. If you live in Doral, keep the shutoff valve location written down.
What happens if I forget to disconnect my garden hose?
A connected hose traps water in the faucet and pipe. When that water freezes, it expands and can crack the pipe or the faucet body. The damage may not show until you turn the water back on and find a leak. Disconnecting hoses is one of the easiest and most important steps.
Can I use antifreeze in my outdoor pipes?
No. Automotive antifreeze is toxic and not meant for plumbing. RV antifreeze is sometimes used in drains, but it should not be used in drinking water lines. The safest method is to drain the pipes completely and shut off the water supply. If you need help, ask a local water damage pro for advice.
