How to Winterize Your RV for Texas Winters

Texas winters have a reputation for being mild — and most of the time, they are. But the Houston area has seen hard freezes that caught residents off guard, and an unprepared RV can suffer serious plumbing damage in a single night below 28°F.

The good news: winterizing an RV in Texas doesn't require the full treatment you'd need in Minnesota. A few targeted steps will protect your rig through even the worst Gulf Coast cold snaps.

Counterintuitively, mild-climate areas like Houston often suffer more freeze damage than colder regions. Here's why:

• Residents aren't in the habit of protecting pipes
• Infrastructure (including RV plumbing) isn't insulated for sustained cold
• Freezes often come suddenly, with little warning
• Temperatures can drop from 60°F to 20°F in 24 hours

A hard freeze in Texas is typically brief — 12 to 48 hours — but that's enough to burst an unprotected water line or damage a pump.

In an RV, the most freeze-vulnerable components are:

• Fresh water lines (especially any exposed runs under the RV)
• Water pump
• Water heater
• Holding tank valves
• Any external water connections (the hose from the park hookup to your RV)

For Texas winters, full antifreeze treatment (blowing out lines and adding RV antifreeze) is usually overkill unless you're leaving the RV unoccupied for an extended period.

For occupied RVs during a freeze event:

Heat tape — Wrap exposed water lines and the connection point at your hookup with self-regulating heat tape. It's inexpensive, easy to install, and activates automatically when temperatures drop.

Foam pipe insulation — Add foam insulation sleeves over any exposed lines. This slows heat loss and buys time during a brief freeze.

Insulate your hose — The water hose running from the park hookup to your RV is often the first thing to freeze. Wrap it in heat tape and foam, or disconnect it and use your onboard fresh water tank during freeze events.

The simplest protection is maintaining interior heat. If your RV stays above 55°F inside, your interior plumbing is safe.

During a freeze event:

• Keep your furnace running (propane furnace is more reliable than electric heat strips in extreme cold)
• Open cabinet doors under sinks to let warm air reach the pipes
• If you have a skirt around your RV, make sure it's in place to trap heat under the rig

During a hard freeze, let your faucets drip slightly — both hot and cold. Moving water is much harder to freeze than standing water. This is a simple, effective precaution during the worst nights.

If a line does freeze and burst, you need to be able to shut off your water supply immediately. Know where your main water shutoff is at the park hookup and at your RV's inlet. Practice it before you need it.

Gray and black tank valves can freeze in sustained cold. Keep your gray tank valve closed (rather than leaving it open to drain continuously) during freeze events — a full tank is harder to freeze than an empty one with residual moisture.

If you have tank heater pads, make sure they're functioning before winter arrives.

If you turn on a faucet and get no water during a freeze:

1. Don't panic — a frozen line isn't necessarily a burst line
2. Apply gentle heat — use a hair dryer on low, working from the faucet back toward the source
3. Never use an open flame — propane torches have caused RV fires
4. Check for damage — once thawed, run water and check for leaks before assuming everything is fine

The best time to prepare is before a freeze is forecast. In the Houston area, that means getting ready in October or November.

A pre-winter checklist:

• Inspect all water line connections for existing cracks or wear
• Install or check heat tape on exposed lines
• Test your furnace (don't wait for the first cold night)
• Stock extra propane — demand spikes during freezes
• Have a backup electric space heater for emergencies
• Know your park's emergency contact number
