How to Use
- Enter your pool volume in gallons or liters
- Enter your pump flow rate in GPM or LPM
- Set desired water turnovers per day (typically 1-2)
- Click calculate to see recommended run time
What is Water Turnover?
Water turnover refers to the time it takes for your pool pump to circulate the entire volume of water in your pool through the filtration system once. For example, if your pool holds 20,000 gallons and your pump moves 50 gallons per minute, one complete turnover takes 400 minutes (6.67 hours).
Most pool experts recommend 1-2 complete turnovers per day for residential pools to maintain clean, healthy water. Commercial pools or heavily used pools may require more frequent turnovers.
Recommended Turnovers by Pool Type
| Pool Type | Recommended Turnovers | Run Time Factor |
|---|---|---|
| Residential Pool | 1-2 per day | Standard |
| Hot Tub/Spa | 2-4 per day | Higher frequency |
| Commercial Pool | 4-6 per day | Maximum filtration |
| Indoor Pool | 1-2 per day | Less debris |
| Pool with Heavy Use | 2-3 per day | More filtration needed |
| Pool with Cover | 1 per day | Minimal debris |
Factors Affecting Pump Run Time
- Pool size and volume - Larger pools need longer run times
- Pump flow rate - Higher GPM means shorter run times
- Pool usage - More swimmers means more debris and contaminants
- Weather conditions - Hot weather and storms increase debris
- Surrounding environment - Trees and vegetation add more debris
- Pool cover usage - Covers reduce debris and evaporation
- Water chemistry - Poor chemistry may require longer filtration
- Filter condition - Clean filters work more efficiently
Energy Savings Tips
Pool pumps can be one of the largest energy consumers in your home. Here are ways to optimize energy usage while maintaining clean water:
- Run pump during off-peak electricity hours if you have time-of-use rates
- Consider a variable-speed pump which can save 50-75% on energy costs
- Split run time into multiple sessions throughout the day
- Clean or backwash filters regularly for optimal efficiency
- Use a pool cover to reduce debris and evaporation
- Ensure pump is properly sized for your pool
- Check for leaks that waste water and energy
- Consider a timer to automate pump operation
Pool Pump Maintenance
- Clean pump strainer basket weekly
- Check and maintain proper water level
- Inspect pump for leaks or unusual noises
- Backwash or clean filter as recommended
- Lubricate O-rings and gaskets annually
- Winterize pump properly in cold climates
- Keep pump area clean and well-ventilated
- Schedule professional inspection annually
Frequently Asked Questions
- How many hours per day should I run my pool pump?
- Most residential pools need 8-12 hours of pump operation per day for one complete turnover. The exact time depends on your pool volume and pump flow rate. In summer or with heavy use, you may need to run it longer.
- Can I run my pool pump too much?
- While over-filtering won't harm your pool, it wastes energy and increases wear on your pump. Running your pump for 1-2 complete turnovers per day is typically sufficient for clean, healthy water.
- Should I run my pool pump during the day or night?
- Running during the day is generally better because that's when the pool is used most and when algae growth is highest due to sunlight. However, if you have time-of-use electricity rates, running at night during off-peak hours can save money.
- What is GPM and how do I find my pump's flow rate?
- GPM stands for Gallons Per Minute, which measures how much water your pump moves. You can find this specification on your pump's label, in the owner's manual, or by checking the manufacturer's website with your pump model number.
