If You Have Power During Freezing Temperatures

Keep water moving at all times

• Run your pool pump continuously (24/7) during the freeze.

• Moving water is far less likely to freeze than standing water.

• If you have variable-speed pumps, even a low-speed circulation is effective.

Use freeze protection settings (if equipped)

• Many modern pool controllers automatically turn equipment on when temperatures drop.

• Double-check that freeze protection is enabled and functioning.

Consider raising the water temperature

• If you have a heater and expect no power interruptions, raising the water temperature slightly can help protect plumbing and equipment.

• Even a small temperature increase can help stabilize exposed lines.

Keep valves open

• Ensure all return lines, spa lines, and water features remain open so water continues circulating everywhere.

⚠️ If You Expect or Experience a Power Outage

Freezes + no circulation = the highest risk scenario.

If power is lost for more than ~60 minutes:

• Shut off all breakers to pool equipment immediately

• Drain water from:

  • Pump housing

  • Filter tank

  • Heater

  • Chlorinator

• Open all drain plugs and air relief valves

• Remove pump lids and store them indoors if possible

This allows any remaining water to expand safely instead of cracking expensive components.

Even a small amount of trapped water can cause serious damage once it freezes.

Extra Tips for Southern Pools

• Do not rely on pool covers alone — covers help reduce heat loss but do not prevent plumbing from freezing

• Protect exposed equipment by wrapping pumps and pipes with towels, insulation blankets, or freeze covers

• Water features and deck plumbing (sheer descents, fountains, cleaners) are often the first to freeze — keep them circulating or fully drained

• Salt systems should remain flowing; stagnant saltwater can freeze faster than expected
