1. What is Pool Filter Pump Size?

Pool filter pump size refers to the flow rate capacity required to properly circulate and filter your pool water. It is measured in gallons per hour (GPH) and determines how quickly the pump can turn over the entire pool volume.

2. How Does the Calculator Work?

The calculator uses the pump size formula:

Where:

• \( \text{Pool Volume} \) — Total water volume in gallons
• \( \text{Turnover Time} \) — Desired time to filter entire pool volume in hours
• \( \text{Pump Size} \) — Required pump capacity in gallons per hour

Explanation: This calculation ensures your pump can circulate the entire pool volume within your desired timeframe for proper filtration and water quality.

3. Importance of Proper Pump Sizing

Details: Correct pump sizing is essential for efficient pool operation. An undersized pump won't properly filter the water, while an oversized pump wastes energy and can damage the filtration system.

4. Using the Calculator

Tips: Enter pool volume in gallons and desired turnover time in hours. Standard turnover times are typically 6-8 hours for residential pools. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the ideal turnover time for a pool?
A: Most residential pools require 6-8 hour turnover times. Commercial pools may need faster turnover rates (2-4 hours).

Q2: How do I calculate my pool volume?
A: For rectangular pools: Length × Width × Average Depth × 7.5. For circular pools: π × Radius² × Average Depth × 7.5.

Q3: What happens if my pump is too small?
A: Inadequate filtration, poor water circulation, algae growth, and inefficient chemical distribution throughout the pool.

Q4: Can a pump be too large for my pool?
A: Yes, oversized pumps cause high energy costs, increased wear on filters, and potential damage to the plumbing system.

Q5: Should I consider other factors besides pump size?
A: Yes, also consider total dynamic head (TDH), pipe size, filter type, and any additional water features when selecting a pump.
