How to Winterize Your Outdoor Water Fountain

As temperatures drop, your outdoor water fountain needs proper care to survive the winter without cracking, pump damage, or costly repairs. Winterizing your fountain is one of the most important seasonal maintenance tasks you can do — and it's easier than you think.

Why Winterizing Your Fountain Matters

Water expands when it freezes. If water remains inside your fountain's basin, pipes, or pump during a hard freeze, the pressure can crack stone, resin, or ceramic — causing irreversible damage. A proper winterization routine protects your investment and ensures your fountain is ready to run beautifully come spring.

When Should You Winterize?

Start the winterization process when nighttime temperatures consistently drop below 40°F (4°C). Don't wait for the first hard freeze — by then, it may be too late to prevent damage.

Step-by-Step: How to Winterize Your Outdoor Water Fountain

Step 1: Turn Off and Unplug the Pump

Switch off your fountain pump and unplug it from the power source. Never leave a pump running in a fountain that's being winterized — running a pump without adequate water flow can burn out the motor.

Step 2: Remove the Pump

Take the submersible pump out of the basin. Rinse it thoroughly with clean water to remove algae, mineral deposits, and debris. Store it indoors in a bucket of clean water or in a frost-free location — this prevents the pump seals from drying out and cracking.

Step 3: Drain All Water from the Fountain

Remove as much water as possible from the basin, tiers, and any internal tubing. Use a wet/dry vacuum, sponge, or towels to absorb remaining moisture. Pay special attention to low points where water can pool and freeze.

Step 4: Clean the Fountain

Before covering or storing, give your fountain a thorough cleaning:

• Scrub the basin with a soft brush and mild soap or white vinegar solution
• Remove algae, mineral scale, and debris from all surfaces
• Rinse thoroughly and allow to dry completely

Step 5: Inspect for Cracks or Damage

While the fountain is clean and dry, inspect all surfaces for hairline cracks, chips, or damaged sealant. Address any issues now with a waterproof fountain sealant — it's far easier to repair in dry conditions than in spring.

Step 6: Cover or Store the Fountain

• Small fountains: Move indoors to a garage, shed, or basement if possible
• Large fountains: Cover with a breathable, waterproof fountain cover designed for outdoor use. Avoid plastic tarps that trap moisture and promote mold
• Resin fountains: Our UV-resistant resin fountains are highly durable, but covering them still protects against debris and UV degradation during winter months

Step 7: Secure the Cover

Use bungee cords or tie-downs to secure the cover against winter winds. Check periodically throughout winter to ensure the cover remains in place and no water has pooled on top.

Special Considerations by Fountain Material

• Resin/fiberglass: Most durable in freeze-thaw cycles; still drain completely and cover
• Concrete/stone: Most vulnerable to freeze damage; must be fully drained and sealed
• Ceramic: Very susceptible to cracking; store indoors whenever possible
• Cast iron: Drain completely; apply a light coat of oil to prevent rust

Spring Startup Checklist

• Remove the cover and inspect for any winter damage
• Reinstall the pump and reconnect tubing
• Fill the basin with fresh water
• Plug in and test before adding any water treatments
• Clean and treat the water with a fountain enzyme treatment

Final Thoughts

A little preparation in autumn saves you from expensive repairs in spring. Taking 1–2 hours to properly winterize your outdoor water fountain protects your investment and ensures it's ready to create that beautiful, calming water sound the moment warm weather returns.
