Winterize Your Texas Well in One Afternoon
Texas may not see long, frozen winters — but one hard freeze is all it takes to burst pipes or damage your well system. Every year, homeowners are surprised by how quickly a cold front can knock out water flow. The good news? You can winterize your well in just one afternoon with a few smart steps that protect your pump, pipes, and water quality all season long.
Why Winterizing Your Well Matters
Unlike municipal water systems, private wells are fully exposed to outdoor temperatures. The pump, pressure tank, and above-ground plumbing can freeze when temps drop below 32°F for even a few hours. Freezing expands water in pipes, causing cracks, leaks, or full bursts that can cost thousands to repair. A few preventive measures can safeguard your system and keep your water flowing all winter.
Step-by-Step: How to Winterize Your Well
1. Insulate Exposed Components
Wrap above-ground pipes, pressure tanks, and fittings in foam insulation or heat tape. Focus on exposed sections near the wellhead or inside unheated pump houses. Secure insulation with waterproof tape to prevent moisture damage.
2. Seal the Well Cap and Conduit
Inspect your wellhead. The cap should be tightly sealed, with conduit connections secured to keep out water, insects, and freezing air. If it’s cracked or loose, replace it before winter. A professional well inspection can confirm your setup is weather-tight.
3. Protect the Pump and Pressure Switch
Cover the pump and pressure switch with an insulated box or heat lamp setup. Keep electrical safety in mind — use outdoor-rated extension cords and thermostatically controlled heat sources only.
4. Drain Unused Lines
If you have outdoor faucets, garden spigots, or irrigation lines connected to your well, shut off water and open valves to drain them completely. Use air pressure to blow out irrigation systems where possible.
Extra Protection for Extended Freezes
- Let indoor faucets drip slightly to keep water moving.
- Keep the well house door closed and insulated with weather stripping.
- Check pressure regularly during cold snaps — if it drops suddenly, ice may be forming in the lines.
Common Winter Well Problems
- Frozen pressure switch: If your pump won’t start, the switch may have ice buildup inside the housing.
- Burst PVC fittings: Common in shallow wells and irrigation lines.
- Low pressure: A small ice plug can block flow and trick the pump into cycling repeatedly.
Frequently Asked Questions
Do I need to shut off my well during freezing weather?
No, but make sure the pump and pipes are insulated. Continuous low flow helps prevent freezing.
Can I use a heat lamp to protect my well?
Yes, but only use a weatherproof, outdoor-rated lamp with a thermostat. Keep it clear of insulation or flammable material.
Should I drain my pressure tank for winter?
Only if the system won’t be used for months. Otherwise, keep it pressurized and insulated to prevent damage.
What if my well freezes?
Turn off power to the pump immediately to prevent motor damage. Then call 77 Water Well — our technicians can safely thaw and inspect your system.
