1. Keep the Water Moving (Most Important)
-
Run the pump continuously when air temps hit ~32°F (0°C) or below.
-
Moving water is much less likely to freeze than still water.
-
If you have variable speeds, run low speed nonstop.
👉 If power is cheaper overnight where you live, it’s still worth running it 24/7 during a hard freeze.
2. Use Freeze Protection (If You Have It)
-
Many modern systems automatically turn on the pump when temps drop.
-
Test it before the freeze hits—don’t assume it’s working.
-
Set freeze protection to activate around 36–38°F to be safe.
3. Don’t Drain the Pool
-
Never drain the pool during freezing weather.
-
Water helps stabilize the structure and protects against ground pressure.
-
Low water levels can also expose skimmers and plumbing to freezing.
4. Protect Exposed Equipment
-
Wrap pipes, valves, and above-ground plumbing with foam insulation or towels.
-
Cover the pump motor with a breathable cover (NOT airtight plastic).
-
Avoid direct contact between covers and electrical components.
5. Skimmers & Water Features
-
Keep water mid-skimmer level so it can flow properly.
-
Turn off:
-
Waterfalls
-
Deck jets
-
Fountains
These freeze faster due to thin water flow.
-
6. Saltwater Pools (Extra Care)
-
Salt systems usually shut off below ~50°F — that’s normal.
-
Still run the pump even if chlorine production stops.
-
Test chlorine manually during extended cold snaps.
7. If Power Goes Out
-
Immediately turn off the breaker to prevent damage when power returns.
-
If possible, open drain plugs on pump and filter only if freezing is prolonged and circulation is impossible.
-
Once power returns, restart circulation ASAP.
8. After the Freeze
-
Inspect for leaks, cracks, or air in the system.
-
Rebalance water chemistry if circulation was interrupted.
-
Call a pro if you notice low pressure or strange noises.
Bottom Line
If you remember just one thing:
Run the pump and keep water moving.
That alone prevents most freeze damage.
