Why Winter Storm Pool Prep is Critical
Winter storms pose unique threats to pools beyond normal winter conditions. Heavy snowfall creates excessive weight on covers potentially causing collapse or damage. Ice storms coat equipment and covers with thick ice layers causing structural stress. Rapid temperature fluctuations create freeze/thaw cycles that crack surfaces and plumbing. High winds tear improperly secured covers and blow debris into pools. Power outages disable cover pumps allowing water accumulation and ice dam formation.
Without proper winter storm preparation, pools suffer extensive damage including cracked pool walls and floors from ice expansion ($1,000 to $3,000 repairs), split plumbing lines from frozen water ($200 to $500 per location), damaged equipment from freeze damage ($300 to $2,000 per piece), torn or collapsed covers from snow weight ($200 to $1,000 replacement), and surface staining from debris and organic matter ($500 to $2,000 cleanup). The cumulative cost of winter storm damage can exceed $10,000 for severe cases.
Proper winter storm preparation prevents these problems through systematic execution of five essential steps that protect pools from storm specific threats. The investment in preparation (4 to 6 hours labor, $200 to $400 in supplies) is minimal compared to potential damage costs and ensures pools survive even severe winter storms without significant damage.
Step 1: Clean and Balance the Water
Clean, balanced water before winter storms provides the foundation for effective storm protection and prevents water quality problems during dormancy.
Thorough Pool Cleaning
Remove all debris from the pool using equipment like the Deluxe Pool Leaf Skimmer Net. Brush all surfaces with quality brushes like the Swimline H2O Pro Pool Brush to dislodge algae and biofilm. Vacuum the pool bottom using equipment like the XtremepowerUS Automatic Pool Cleaner. Empty skimmer and pump baskets. Clean or backwash the filter thoroughly.
Cleaning before winter storms ensures debris does not decompose during winter consuming winterizing chemicals and creating water quality problems. Organic matter left in pools provides nutrients for algae growth even in cold water. Thorough cleaning eliminates this problem and ensures winterizing chemicals work on water chemistry rather than being consumed by contaminants.
Complete Water Chemistry Balancing
Test all water parameters using quality kits like the Taylor K-2005 Complete Test Kit. Adjust pH to 7.4 to 7.6 using pH increaser or decreaser. Balance total alkalinity to 80 to 120 ppm using alkalinity increaser. Ensure calcium hardness is 200 to 400 ppm for concrete pools or 150 to 250 ppm for vinyl pools. Proper chemistry prevents corrosion from low pH, scaling from high pH, and surface etching from aggressive water.
Add Winterizing Chemicals
Use comprehensive winterization kits like In The Swim Pool Winterizing Kit or Winter Care Pool Closing Kits. Add shock treatment to eliminate bacteria. Add winterizing algaecide at 2 to 4 times normal dose for 3 to 6 months protection. Add stain and scale preventer to sequester metals and minerals. Run pump 8 to 12 hours to circulate all chemicals throughout the pool.
Step 2: Lower the Water Level
Lowering water level before winter storms is critical for preventing freeze damage to skimmers, return lines, and pool structure.
Why Water Level Matters
Water expands approximately 9 percent when it freezes, generating forces exceeding 25,000 pounds per square inch. If water remains in skimmers and return lines during freezing temperatures, this expansion cracks skimmer throats, splits return fittings, and damages plumbing. Lowering water below these components prevents water from entering them, eliminating freeze damage risk.
Proper Water Level for Winter Storms
Lower water to 4 to 6 inches below the skimmer opening for in ground pools. This level prevents water from entering skimmer and return lines while maintaining adequate water for pool structure support. For above ground pools, follow manufacturer specifications (typically 3 to 4 inches below skimmer). Use a submersible pump for efficient water removal. For typical pools, expect to remove 500 to 3,000 gallons depending on pool size and skimmer placement.
Never Drain Pools Completely
Never drain pools completely before winter storms. Water weight counteracts ground pressure from surrounding soil and groundwater. Empty pools can crack from ground pressure, pop out of the ground in high water table areas, or suffer liner damage from exposure. Maintain proper water level (4 to 6 inches below skimmer) to protect pool structure while preventing freeze damage to components.
Step 3: Protect the Pool Equipment
Pool equipment requires comprehensive protection from winter storm conditions including freezing temperatures, snow, ice, and wind.
Drain All Equipment Completely
Turn off power to pump at the breaker. Remove all pump drain plugs and allow complete drainage. Tilt pump if necessary to ensure all water drains. Open filter drain plugs and air relief valves to allow complete drainage. For cartridge filters, remove cartridges and store indoors. Drain heaters completely following manufacturer instructions. Leave all drain plugs out throughout winter. Store drain plugs in pump basket so they are not lost.
Blow Out Plumbing Lines
Use a shop vacuum or air compressor to blow water from all plumbing lines including skimmer lines, return lines, and main drain lines. Continue until no more water emerges from jets and drains. This critical step removes residual water that could freeze and crack pipes. Install winterizing plugs like winterizing test plugs in all lines after blowing them out. Add pool grade antifreeze to lines that cannot be completely drained.
Install Gizzmos and Cover Equipment
Install Gizzmos (expansion plugs) in skimmers to absorb ice expansion and protect skimmer throats from cracking. Cover pumps, filters, and heaters with weatherproof covers to protect from snow, ice, and debris. For above ground pools, disconnect and store all equipment indoors in climate controlled environments for maximum protection from winter storms.
Step 4: Install a Winter Pool Cover
Quality winter covers properly installed provide critical protection from winter storm debris, snow, ice, and wind.
Choose the Right Cover Type
Solid safety covers like the Swimline Winter Pool Cover provide maximum protection blocking all sunlight, supporting significant snow weight, and lasting 10 to 15 years. Mesh safety covers allow water drainage, block most sunlight, and last 12 to 15 years. Standard winter covers are economical but require cover pumps and last 3 to 5 years. For winter storm protection, solid or mesh safety covers provide superior performance compared to standard covers.
Proper Cover Installation
Clean the cover if previously used. Spread evenly over the pool ensuring it extends beyond pool edges on all sides. For safety covers, attach springs to deck anchors working systematically around the pool to ensure even tension. For standard covers, secure with water bags filled 2/3 full and spaced 2 to 3 feet apart. Use 15 to 25 water bags for typical pools. Never use hard objects like concrete blocks that can damage covers.
Above Ground Pool Covers
For above ground pools, install an air pillow like the 4 foot winterizing air pillow before installing the cover. Inflate to 60 to 70 percent capacity and secure with light rope. The pillow creates a peak that sheds snow and water while absorbing ice expansion pressure protecting pool walls. Install the cover over the pillow and secure with cable and winch system or water bags.
Install Cover Pump
If using a solid cover, install an automatic cover pump like the Coverblast Pool Winter Cover Pump Attachment to remove accumulated water. Position the pump in the lowest point where water naturally collects. Direct discharge hose away from the pool area. Cover pumps prevent water accumulation that creates excessive weight and ice dam formation during winter storms.
Step 5: Monitor and Maintain Throughout Winter
Active monitoring and maintenance throughout winter prevents small problems from becoming major damage during winter storms.
Regular Winter Inspections
Check pools at least monthly during normal winter conditions, increasing to weekly or bi weekly during winter storm warnings. Inspect covers for damage including tears, separations, or sagging. Check water level and add water if needed. Verify cover pump is operating if installed. Look for signs of ice damage or equipment problems. Document conditions with photos for insurance purposes if needed.
Snow Removal from Covers
Remove snow from covers when accumulation exceeds 6 to 8 inches to prevent excessive weight. Use a soft broom, cover rake, or leaf blower to remove snow gently. Never use sharp shovels or metal tools that can tear covers. Work from pool edges toward center to avoid stepping on covers. For heavy snow (over 12 inches), remove snow in stages rather than all at once to prevent sudden weight shifts that could damage covers.
Ice Management
Never attempt to break ice on pool surfaces or covers as this can damage liners and covers. Allow ice to melt naturally. If ice dams form on covers preventing drainage, use warm (not hot) water to melt channels for drainage. Ensure cover pumps remain operational during ice storms by bringing them indoors during extended freezing periods and reinstalling when temperatures moderate.
Debris Removal
Remove leaves, branches, and other debris from covers regularly to prevent organic matter from decomposing and staining covers. Heavy debris also adds weight and can puncture covers. Use a leaf blower or soft broom to remove debris gently without damaging covers.
Emergency Storm Preparation
When severe winter storms are forecast, take additional precautions including ensuring cover pumps are operational and have power, removing any loose items from pool area that could blow onto covers, checking that covers are secured properly, and having emergency supplies ready (tarps, rope, additional water bags) in case covers are damaged during storms.
