1. What Is Water Sump Capacity?

Water sump capacity refers to the total volume of water that can be stored in a sump tank. It's calculated by multiplying the length, width, and height of the sump's interior dimensions.

2. How Does the Calculator Work?

The calculator uses the volume formula:

Where:

• \( V \) — Volume in cubic feet
• \( L \) — Length in feet
• \( W \) — Width in feet
• \( H \) — Height in feet

Explanation: This formula calculates the total volume of a rectangular prism, which is the standard shape for most water sumps.

3. Importance of Sump Capacity Calculation

Details: Knowing your sump capacity helps in proper water management, determining pump requirements, and ensuring adequate water storage for your needs.

4. Using the Calculator

Tips: Measure the interior dimensions of your sump in feet. Enter length, width, and height in the corresponding fields. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I convert cubic feet to gallons?
A: Multiply cubic feet by 7.48052 to get gallons (1 cubic foot ≈ 7.48 gallons).

Q2: What if my sump isn't rectangular?
A: For cylindrical sumps, use π × r² × h (where r is radius). For irregular shapes, consult a professional.

Q3: Should I include the sump walls in measurements?
A: No, use only the interior dimensions (water-holding space) for accurate capacity calculation.

Q4: How often should I check my sump capacity?
A: Whenever you modify your sump or if you notice changes in water storage performance.

Q5: What's the average sump size for a house?
A: Residential sumps typically range from 20-60 cubic feet (150-450 gallons), but needs vary based on water usage.
