Your details

Everything updates as you change it. Nothing is sent anywhere.

Flow rate in gallons per minute. Anything installed before 1994 is likely 5.0 gpm.

Gallons per week during the dry season.

Gallons lost to evaporation each month. Desert summers run at the high end.

Heavy hot water demand

At this volume a single 40 gallon tank tends to run short during morning peaks. Worth comparing a larger tank against a tankless unit before yours fails.

Estimates use typical fixture flow rates and average habits. Actual use varies with appliance efficiency, irrigation controllers and household routine. A large gap between this estimate and your bill is worth investigating as a leak.
