Quick Answer
Pool pipe winterization involves draining water from all plumbing lines to prevent freeze damage. Key steps: blow out lines with air compressor, drain equipment, add pool antifreeze to traps and low points, install winterization plugs, and protect exposed pipes. Even Texas pools need winterization during freeze warnings to prevent costly pipe bursts and equipment damage.
Why Winterization is Critical
Freeze Damage Prevention
Water expands approximately 9% when it freezes, creating tremendous pressure inside pipes and equipment. This expansion can crack pipes, damage equipment housings, and destroy expensive components. Even brief freezes can cause thousands of dollars in damage.

Components at Risk:
- •Pool pump and motor housings
- •Filter housings and tanks
- •Heater heat exchangers
- •Chlorinator cells and housings
- •Above-ground plumbing lines
- •Valve bodies and fittings
Typical Damage Costs:
- 💰Pump housing replacement: $300-800
- 💰Filter tank replacement: $400-1000
- 💰Heater heat exchanger: $800-2000
- 💰Underground pipe repair: $1000-5000
- 💰Complete system damage: $3000-10000
Winterization Methods
1. Continuous Equipment Operation (Light Freezes)
When Appropriate:
- • Brief freeze periods (under 12 hours)
- • Temperatures between 25-32°F
- • All equipment functioning properly
- • Adequate electrical power available
- • Minimal wind and weather protection
Operation Method:
- • Run pump and heater continuously
- • Keep all valves open for circulation
- • Monitor equipment every few hours
- • Have winterization supplies ready
- • Switch to full winterization if needed
Risk: Equipment failure during freeze leaves system unprotected. Always have backup winterization plan ready.
2. Partial Winterization (Moderate Freezes)
When Used:
- • Extended freezes (12-48 hours)
- • Temperatures between 20-25°F
- • Some equipment protected, some exposed
- • Quick return to service needed
- • Moderate freeze protection required
Procedures:
- • Drain exposed equipment only
- • Blow out above-ground lines
- • Add antifreeze to vulnerable areas
- • Keep underground lines full
- • Install temporary insulation
3. Complete Winterization (Severe Freezes)
When Required:
- • Extended hard freeze (2+ days)
- • Temperatures below 20°F
- • High winds increasing freeze risk
- • Equipment power loss risk
- • Maximum protection needed
Complete Process:
- • Drain all equipment completely
- • Blow out all plumbing lines
- • Add antifreeze to all trap areas
- • Install winterization plugs
- • Protect exposed components
Step-by-Step Diagnosis
Assess System Complexity
Map out all pool plumbing lines: main drains, skimmers, returns, spa lines, heater connections, and auxiliary equipment. Complex systems with multiple zones require more thorough winterization procedures.
⚠️ Warning: Missing any line during winterization can cause expensive freeze damage.
💡 Pro Tip: Draw a simple diagram of your pool's plumbing layout.
Check Weather Forecast
Monitor extended forecasts for freeze warnings. In Dallas-Fort Worth, winterize when temperatures will drop below 25°F for extended periods. Brief freezes may only require running equipment continuously.
⚠️ Warning: Don't wait until freezing weather arrives - winterize in advance.
💡 Pro Tip: Set up weather alerts for freeze warnings in your area.
Inventory Winterization Supplies
Gather necessary supplies: shop vacuum or air compressor, pool antifreeze (propylene glycol), winterization plugs, Gizzmos for skimmers, and basic tools. Having everything ready speeds the process.
⚠️ Warning: Never use automotive antifreeze - it's toxic to pool systems.
💡 Pro Tip: Keep winterization supplies on hand during winter months.
Test Equipment Function
Ensure all valves operate properly and multiport valve moves to all positions. Test that drains and plugs are accessible. Equipment problems discovered during emergency winterization create additional complications.
⚠️ Warning: Stuck valves during freezing weather prevent proper winterization.
💡 Pro Tip: Practice valve operations before freeze emergencies.
Plan Winterization Sequence
Determine order of operations: which lines to blow out first, equipment to drain, and antifreeze application points. Proper sequence prevents water from flowing back into cleared lines.
⚠️ Warning: Wrong sequence can refill already-cleared lines with water.
💡 Pro Tip: Start with highest elevation lines and work down.
Complete Winterization Process
Step-by-Step Winterization Procedure
Step 1: Equipment Shutdown and Drainage
- • Turn off all electrical power to pool equipment
- • Close main drain and skimmer valves
- • Set multiport valve to "Waste" position
- • Remove pump basket and drain pump housing
- • Remove drain plugs from all equipment
Step 2: Line Blow-Out Process
- • Connect air compressor or shop vacuum to skimmer
- • Open one return line at a time
- • Blow air until only air comes from return
- • Close return valve and move to next line
- • Blow out main drain line last
Step 3: Antifreeze Application
- • Use only propylene glycol pool antifreeze
- • Add 1-2 quarts to each skimmer
- • Pour antifreeze into main drain if accessible
- • Add to equipment low points and traps
- • Install Gizzmos in skimmer throats
Step 4: System Isolation and Protection
- • Install winterization plugs in all return fittings
- • Close and lock all valves in neutral position
- • Cover exposed equipment with insulating materials
- • Remove or drain automatic cleaning systems
- • Document valve positions for spring startup
Equipment-Specific Winterization
Protecting Different Pool Components
Pool Pumps and Motors
Winterization Steps:
- • Remove all drain plugs from pump housing
- • Remove pump basket and lid
- • Blow out pump housing with compressed air
- • Store drain plugs in pump basket
Protection Tips:
- • Cover motor with waterproof cover
- • Keep drain plugs easily accessible
- • Don't reinstall plugs until spring

Frequently Asked Questions
Do I need to winterize pool pipes in Texas?
Yes, even in Texas pools need winterization during freeze warnings. Dallas-Fort Worth experiences periodic freezes that can burst exposed pipes and damage equipment. Proper winterization includes blowing out lines, draining equipment, and adding antifreeze to prevent costly freeze damage.
How do you blow out pool lines for winter?
Blow out pool lines using a shop vacuum or professional air compressor connected to skimmer or dedicated blow-out port. Close main drain, set multiport to waste, and blow air through each line until only air comes out. Add antifreeze to trap and low points after blowing out water.
What temperature should I winterize my pool?
Winterize pool when temperatures are expected to drop below 32°F (0°C) for more than 4-6 hours. In Dallas-Fort Worth, monitor weather forecasts from December through February and winterize when freeze warnings are issued, typically when temps will be 25°F or lower.
Can I winterize my pool myself?
Basic winterization can be DIY, but proper line blow-out requires experience and equipment. Mistakes can cause expensive freeze damage. Professional winterization ensures all lines are properly cleared and protected. Complex systems with multiple returns, spas, or heaters need professional service.
