What does the efficiency setting change?

Efficient fixtures reduce shower, toilet, laundry, and dishwashing estimates. Older fixtures increase those estimates to model higher-flow equipment.

Can I use cubic meters instead of liters?

Yes. Switch the display unit to cubic meters if your water bill or meter reports usage in m³.

Find the habits that move the water meter

Most household water use is not one dramatic leak. It is repeated minutes, flushes, loads, and watering sessions. Model the routine first, then decide which habit is easiest to change.

"The fastest wins usually come from shower duration, toilet/fixture efficiency, and outdoor watering because they repeat at high volume."

Start with daily routines

Shower minutes and flushes happen every day, so small changes compound quickly across a household.

Check fixture age

Low-flow showerheads, efficient toilets, and full appliance loads can materially change the estimate without changing comfort.

Watch outdoor water

Garden watering can dominate the chart. If outdoor use is high, adjust timing, soil moisture, or irrigation duration first.
