Winterizing Your Plumbing: How to Prevent Burst Pipes, Backflows, and Outdoor Damage
Even though Gainesville winters don’t bring blizzards or deep freezes, they’re not without risk to your plumbing. A few cold nights are all it takes for unprotected pipes to freeze and burst. Add in the risk of backflow preventers cracking or outdoor hose bibs splitting, and you’ve got a recipe for costly damage.
But the good news? A few proactive steps can keep your plumbing safe all season long. Here’s how to winterize your home’s plumbing and avoid emergencies during North Florida’s cold snaps.
1. Insulate Exposed Pipes
Most Floridians don’t expect frozen pipes to be a problem, which is what makes the issue easy to overlook. However, homes in Florida often don’t have pipe insulation, especially in crawl spaces, garages, or outdoor areas. And when temps dip into the 20s overnight, exposed plumbing is vulnerable.
What to do:
- Wrap pipes in unheated areas (like garages, attics, or crawlspaces) with foam insulation or heat tape.
- Use faucet covers on all outdoor spigots. You can find them at most hardware stores.
Tip: If you’re not sure whether a pipe needs insulation, assume it does. Better to be safe than have a burst pipe.
2. Protect Your Backflow Preventer
Backflow preventers are common in Gainesville homes with irrigation systems. They’re critical for keeping contaminated water out of your drinking supply. Unfortunately, they’re also exposed and susceptible to freezing.
Steps to protect it:
- Insulate your backflow preventer with a cover designed for outdoor valves.
- If possible, shut off and drain the irrigation line for the winter.
- Do not wrap the backflow preventer in plastic. It traps moisture and accelerates damage.

3. Disconnect and Drain Garden Hoses
Leaving a hose attached to your faucet during a freeze can cause water to back up into the pipe and freeze there.
Avoid damage by:
- Disconnecting all hoses before a cold front.
- Draining and storing them in a garage or shed.
- Shutting off any dedicated outdoor water valves if available.
This quick-fix takes two minutes and can save you thousands in pipe repairs.
4. Drip Your Faucets on Freezing Nights
When forecasts show freezing temps overnight, leave a trickle of water running from indoor faucets. The flow helps prevent the water in your pipes from freezing.
Combine this with:
- Opening cabinet doors under sinks to let warm air circulate.
- Keeping your thermostat at a consistent temp (don’t lower it drastically at night).
If you’ve already experienced pipe freezing before, it may be time to have a professional evaluate your insulation and pipe layout.
Concerned About Winter Plumbing? Call Before It’s an Emergency
Cold weather has a way of making small problems worse—like slow leaks, weak pipe fittings, or sediment in your water heater. If you’ve noticed any odd sounds, drips, or inconsistent hot water, it’s better to call a professional for plumbing repair before a cold snap hits.
We recommend calling a plumber if you notice:
- Unusual dripping or puddles under sinks
- Poor water pressure or changes in temperature
- Rusty or discolored water from taps
- Exposed pipes in unheated areas
You don’t have to wait until it’s an emergency. If something feels off, contact J.W. Freeman Plumbing and we’ll take a look before it becomes a bigger issue.
