A polyphosphate doser volumetrically releases preservatives into the water before the heating phase to complex calcium bicarbonate molecules, preventing their precipitation and thereby reducing limescale build-up.
Polyphosphates are food preservatives, but they are still preservatives.
If we need to observe the rule that the water supplied to us at the meter must be kept unchanged (in the case where it is intended for human consumption), we risk heavy penalties, so it’s better to avoid this.
However, if the water is intended for technical purposes, we are not incurring any health sanctions.
For the technical water line (toilet, dishwasher, washing machine…) you are not at risk of health sanctions, but you should be aware of possible corrosion risks since the water is rich in Sodium.
For the water line intended for human consumption, if it is served by the softener, you run the risk of health sanctions since the treated water can no longer be considered suitable for human consumption because its original mineral composition has been changed. This can lead to the health risks previously described for users.
The treatment with the ExtraH2O device does not change the mineral composition of the water being treated.
Calcium, Magnesium, Potassium, and Total Dissolved Solids continue to be present in the treated water in the same quantity as they were originally.
This property allows the nutrients present in the water intended for human consumption to reach our bodies in their original concentration, performing their nutritional and health role with preventative functions for various diseases, including cardiovascular ones.
A reverse osmosis system produces demineralized water.
It is usually placed downstream of the faucet, which is a condition to avoid sanctions as it does not interfere with the plumbing system between the meter (point of entry) and the faucet (point of use).
Calcium, Magnesium, Potassium, and Total Dissolved Solids will be completely removed from your water, depriving it of essential mineral and nutritional elements for your health.
The water now coming out of your reverse osmosis system is suitable for technical use (iron, batteries) but not for food use.
