Pool Fill Time Calculator – Hose & Flow Estimator
Estimate how long it will take to fill your pool with garden hoses or bulk water trucks. Includes a built-in bucket flow test to measure your exact hose flow rate in seconds.
Don't Know Your Hose Flow Rate?
Run a simple 30-second 5-gallon bucket test:

•If you use 2 garden hoses connected to separate hose bibbs with distinct water lines, your fill time will be cut in half.
•Never leave hoses unattended overnight without an auto-shutoff valve or water alarm.
•Check with your municipal water utility: some water suppliers offer sewer fee discounts when filling a new pool.
Tips for Filling Your Pool Efficiently & Safely
Hose Filling Best Practices
When placing a garden hose into an empty pool, tie a clean gym sock or microfiber rag over the hose nozzle to filter out sediment and pipe rust that can permanently stain new plaster or vinyl.
Weight the hose down in the deep end with a plastic-wrapped brick or deck weight so the water jet does not whip around and gouge wet plaster or mar the pool floor.
Garden Hose vs. Water Truck Delivery
Commercial pool water delivery trucks typically carry 5,000 to 6,000 gallons per load and can empty a tanker into your pool in under 20 minutes through high-volume 3-inch discharge hoses.
For homes on private wells, tanker delivery is strongly recommended to protect well pump impellers from overheating and prevent the introduction of dissolved well iron, copper, and manganese.
