Costs & Operations

Operating tools using the rates you enter (no stored tariffs): fill cost and fill time, pump energy cost, turnover flow, filter sizing and water-loss (evaporation vs leak).

Fill CostFind out what it costs to fill your pool with water: enter the gallons and the rate from your utility bill — per gallon, per 1,000 gallons or per CCF.Fill TimeSee how many hours and minutes it takes to fill your pool from a garden hose. Enter gallons and flow in GPM — a typical hose delivers about 9 GPM.Pump Energy CostEstimate the daily, monthly and yearly electricity cost of running your pool pump from its horsepower, motor efficiency, run hours and your own $/kWh rate.Turnover / FlowFind the pump flow in GPM needed to turn over your whole pool within a target number of hours — the basis for sizing pumps, filters and daily run time.Filter SizeFind the minimum filter area for your flow rate using standard design rates for sand, cartridge and D.E. media — size the filter to match your pump flow.Water LossTurn a measured drop in water level into gallons lost and inches per day, and see whether it looks like normal evaporation or a possible leak.

Every Costs & Operations tool is calculated server-side — visible immediately — with its formula, a worked example and a reference table. Background reading is in the guides.
