Calculate Your Needs

How do you choose the resin volume?

Size your water softener in 4 steps

1. Estimate your daily water needs

Simply take your bills for the year, add up the billed water volumes, and divide by the number of days you were at home.

Reference: average water consumption in France is around 150 liters per day per person.

2. Decide on the water volume between regenerations

For example, if you live with your partner, you use about 300 liters of water per day.

If your goal is to regenerate the resin in your Ideal every 7 days on average, you get 2,100 liters.

3. Measure your water hardness

Tests are available as strips or a liquid at any home improvement store.

4. Calculate your resin needs

Calculation formula

Resin volume = Water volume between regenerations × TH / 5,000
