How To Put On A Pool Cover: The Definitive Installation Guide
Mastering how to put on a pool cover protects your investment against harsh winter freezes, reduces chemical evaporation by up to 95 percent, and prevents organic debris from unbalancing your water chemistry. This comprehensive guide outlines the precise steps, safety measures, and anchoring techniques required for both solid safety covers and lightweight solar blankets.
Pre-Installation Preparation and Equipment Checklist
Successfully securing a pool cover requires proper staging, the right accessories, and adherence to manufacturer specifications. Whether you are winterizing an in-ground swimming pool or deploying a solar blanket for summer heat retention, failing to prepare the deck and water surface can tear the vinyl material or strain your anchors.
- Essential Gear and Tools: Cover pump, leaf rake, garden hose, corrosion-resistant brass anchors, tamping tool, hex key, spring covers, water tubes (for solid floating covers), and a push broom.
- Prerequisite Standards: Water level must be maintained precisely 15 to 18 centimeters below the coping for solid safety covers to prevent excessive stress on the mesh and springs, while solar blankets require a completely clean, flat water surface.
- Duration and Crew: Plan for 45 to 90 minutes of labor; enlist at least two adults to safely maneuver heavy-duty mesh or solid safety covers across large rectangular or custom-shaped vessels.
Step-by-Step Pool Cover Installation Procedure
Step 1: Clean and Balance the Water Chemistry
Before covering the pool, remove all floating leaves, twigs, and larger debris using a leaf net. Balance your pH between 7.2 and 7.6, adjust total alkalinity to 80-120 ppm, and apply a heavy-dose winter algaecide to prevent organic growth during the dormant months.
Warning: Never install a cover over untreated water. Trapping algae-prone water beneath an opaque cover for months guarantees a severe green pool opening in the spring.
Step 2: Lower the Water Level and Blow Out Lines
Drain the pool water down to the manufacturer's recommended level, typically 15 to 18 centimeters below the bottom of the tile line or skimmer mouth. For freezing climates, use a commercial shop vacuum or air compressor to blow out all plumbing lines, and thread expansion plugs into the return lines and skimmer throats to prevent structural freeze damage.
Step 3: Unfold and Position the Cover
Lay the cover box or bundle on the deep end deck, and carefully pull the material across the length of the pool. Avoid dragging the cover across rough concrete coping or sharp stone edges to prevent abrasions and pinhole punctures. Center the cover so that you have an even, symmetrical overhang of approximately 30 to 45 centimeters overlapping the pool edge on all sides.
Step 4: Secure the Anchors and Springs
For safety covers featuring brass anchors and tension springs, tap the brass anchors out of their concrete sleeves using a tamping tool or rubber mallet until they pop up fully. Attach the installation rod to the stainless steel springs, hook the spring onto the anchor, and stretch the strap outward.
Pro-Tip: Always secure the cover using a cross-pattern technique. Fasten opposite corners first (north-south, then east-west) to distribute tension evenly across the entire membrane without pulling the cover out of square.
Step 5: Adjust Tension and Install Protective Sleeves
Walk the perimeter of the pool to inspect every spring; each spring should be compressed to approximately 50 percent of its total travel distance to withstand heavy snow loads without bottoming out. Slide vinyl spring covers over the stainless steel springs to protect your concrete coping and pool deck from metal scuff marks and friction wear.

Comparative Analysis of Pool Cover Types
| Cover Type | Primary Function | Expected Lifespan | Winterization Suitability | Maintenance Requirement |
|---|---|---|---|---|
| Mesh Safety Cover | Debris exclusion & child safety | 10 to 15 years | Excellent (allows rainwater to filter through) | Low (blow off leaves; monitor water level) |
| Solid Safety Cover | Total light blockage & safety | 7 to 12 years | Excellent (blocks 100% of sunlight/algae) | High (requires regular pumping of surface water) |
| Solar Blanket | Heat retention & evaporation control | 3 to 5 years | Poor (not rated for snow loads or safety) | Moderate (rinse and store out of direct UV) |
Common Installation Failures and Field Fixes
- Root Cause: The cover sags dangerously into the water under the weight of rain and melting snow.
- Actionable Fix: Adjust the tension straps evenly around the perimeter, ensuring springs are compressed uniformly. If using a solid cover, deploy an automatic cover pump immediately to drain accumulated surface water.
- Root Cause: Brass deck anchors get jammed with dirt, scale, and winter debris, refusing to pop up.
- Actionable Fix: Flush the anchor sleeves thoroughly with a pressurized garden hose and a mild acidic descaling solution. Tap the center pin gently with a rubber mallet to break the mineral bond.
- Root Cause: Friction wear and tearing occur where the cover rubs directly against abrasive stone coping.
- Actionable Fix: Install heavy-duty polyethylene wear strips or protective padding sleeves along the underside of the cover wherever it contacts rough pool coping edges.
Frequently Asked Questions
Can I leave my pool cover on all summer?
No. Standard winter safety covers are designed for off-season dormancy and lack UV inhibitors rated for continuous summer exposure, while solar blankets will degrade rapidly if left on a super-chlorinated pool during peak heat waves. Utilize a solar cover during swimming season only when heating or evaporation control is actively required.
How do I keep rainwater off a solid pool cover?
You must use an electric or manual submersible cover pump placed at the lowest point of the sagging cover. Check the pump weekly during heavy rainfall or snowmelt seasons to prevent excess weight from detaching the safety springs or damaging the cover material.
What is the difference between safety covers and floating covers?
Safety covers are anchored permanently into the surrounding concrete deck with heavy-duty tension springs and can support the weight of adults or pets, whereas floating solar blankets simply rest directly on the water surface and offer zero safety protection against accidental drowning.
How should I store my pool cover for the summer?
Wash the cover thoroughly with a mild, non-detergent soap and a soft-bristle brush, rinse completely with fresh water, and allow it to dry completely in the sun. Fold the clean cover loosely or roll it onto a storage reel, and keep it in a cool, dry, rodent-free shed or garage.
