❄️ Quick Reference
- Purpose: Remove rainwater and melted snow from pool covers
- Activation: Automatic models turn on at 1.5-2.5" water depth (varies by model; can rise in near-freezing conditions)
- Season: Essential fall through spring in most climates
- Capacity: Range from 170 GPH (manual) to 2100+ GPH (automatic). Rated GPH is at minimal head; long ¾" garden hoses can reduce output dramatically
- Temperature: Many rated ~32°F-120°F liquid temp; avoid hard-freeze conditions
Cover pumps are specialized submersible pumps designed to remove accumulated water from pool and spa covers. They're essential winter equipment that prevents cover sagging, tearing, and the buildup of stagnant water that can become a breeding ground for mosquitoes and debris collection.

Why Cover Pumps Are Needed
Pool covers collect rainwater, melting snow, and ice throughout the winter months. Without proper drainage, this water accumulation causes several problems:
- Cover damage: Excessive weight can stretch, tear, or permanently sag covers
- Safety hazards: Standing water on safety covers creates drowning risks
- Pest breeding: Stagnant water becomes mosquito breeding habitat
- Debris collection: Water pools become magnets for leaves, dirt, and organic matter
- Freezing damage: Ice formation can damage both covers and underlying pool equipment
Types of Cover Pumps
Automatic Cover Pumps
These pumps feature built-in float switches that activate when water reaches a preset depth (commonly 1.5-2.5 inches, varies by model) and shut off automatically when water is pumped down to about 3/4-1 inch.
| Capacity | Best For | Features |
|---|---|---|
| 1700-2100 GPH | Large pools, heavy precipitation areas | High capacity, 25' cords, thermally protected motors |
| 1000-1500 GPH | Average pools, moderate climates | Good balance of capacity and energy efficiency |
Manual Cover Pumps
These require manual activation but offer more control and typically cost less. Ideal for situations where you can monitor water accumulation regularly.
Siphon Pumps
Non-electric options that use gravity and siphoning principles. Limited capacity but useful as backup pumps or in areas without electrical access.
• Superior Automatic 2100 GPH - Premium automatic pump with 25' cord
• Complete Cover Pump Collection - Automatic, manual, and siphon options
Choosing the Right Pump
Key Factors to Consider
- Pool size: Larger covers need higher capacity pumps
- Climate: Heavy snow/rain areas benefit from automatic, high-capacity models
- Cover type: Safety covers vs. winter covers have different drainage needs
- Power availability: GFCI-protected outlet within cord reach
- Monitoring ability: Manual pumps require regular checking
- Discharge setup: Use short runs and consider 1" discharge tubing in heavy-rain areas
Capacity Guidelines
- Small pools (under 500 sq ft): 500-1000 GPH sufficient
- Average pools (500-800 sq ft): 1000-1500 GPH recommended
- Large pools (800+ sq ft): 1500-2100+ GPH for quick water removal
Installation & Setup
Placement
Position the pump at the lowest point where water naturally collects on your cover. The large, stable base should sit flat to prevent tipping.
Discharge Setup
Most pumps include adapters for standard garden hoses. Route discharge water away from the pool area to prevent runoff return or ice formation near equipment.
Setup Best Practices
- Test operation: Pour water around pump to verify automatic activation
- Secure cords: Keep electrical connections elevated and protected
- Clear intake: Remove leaves and debris from pump screen regularly
- Plan drainage: Ensure discharge water flows away from pool and walkways
Maintenance
Regular Cleaning
Clean the bottom intake screen weekly during active season. Remove leaves, debris, and any buildup that could clog the impeller.
Seasonal Storage
Before storing, run clean water through the pump to flush debris, then store in a dry location. Most pumps are designed for outdoor storage but benefit from protection.
🗓️ Maintenance Schedule
- Weekly: Check and clean intake screen
- Monthly: Verify proper operation and discharge flow
- Before freezing: Remove pump if temperatures will drop below operating range
- Spring: Test operation before reinstalling
Common Issues & Solutions
Pump Won't Start
- Check GFCI outlet and electrical connections
- Verify float switch isn't stuck (automatic pumps)
- Clean debris from intake screen
- Ensure adequate water depth for activation
Pump Runs But No Water Flow
- Check for clogged intake or discharge
- Verify hose connections are secure
- Prime pump if necessary (check manufacturer instructions)
Pump Runs Continuously
- Float switch may be damaged, stuck, or obstructed
- Pump not level/upright so the switch never reaches "off" position
- Discharge hose routing causes water to run back onto cover (creating continuous cycling)
- Verify pump is stable and properly positioned
Winter Care & Temperature Considerations
Many cover pumps are rated roughly 32°F-120°F liquid temp, but require attention as temperatures approach freezing. Avoid hard-freeze conditions and drain/remove when ice is likely.
🌡️ Temperature Guidelines
- Above 40°F: Normal operation expected
- 35-40°F: Monitor closely; activation depth may increase
- Near 32°F: Remove pump to prevent freeze damage
- Below 32°F: Pump must be removed and stored
Ice Management
If ice forms on your cover, don't chop ice with sharp tools. If you use any melting product, follow your cover manufacturer and avoid de-icers with unknown additives. For detailed winter cover care strategies, see Swim University's comprehensive guide.
❄️ Winter Strategy
In harsh winter climates, consider using your cover pump strategically—deploy during milder periods when water accumulates, then store during extended hard freezes. This protects both your pump investment and maintains cover integrity.
For Spa Covers
Cover pumps work excellently on spa covers, though the smaller surface area means lower-capacity pumps are usually sufficient. The same principles apply: remove standing water to prevent damage and pest issues.
