We would lose money and we would have health risks ...
Well, there must be two of us who are badly informed
it's weird,
for me, minerals are inorganic by nature and the body assimilates them very well since they are necessary.
little pierrot, I'm afraid you’ve read the sellers' ad too much.
at € 8000 + the rental of a second meter,
Water from the public network must meet the drinking conditions defined by the regulations. In this case, it is not advisable to use household treatment systems but rather to regularly take note of the level of potability of the water distributed in order to be able to react quickly.
In the case of water from a private source, domestic treatments can be installed. Although UFC-Que Choisir has not specifically tested reverse osmosis units, we can warn you of the risks arising from these treatments. Indeed, they can cause the rejection of toxic compounds (nitrites, etc.) as well as the development of harmful or even fatal bacteria. In addition, the reverse osmosis filters all the elements of the water, including the mineral salts, which represents a loss of nutritional quality. Finally, the water consumption required is 3 to 4 liters for 1 liter of purified water!
At a minimum, it is imperative to:
- circulate the water regularly to avoid clogging the filter;
- purge the system a few seconds before each use;
- consume purified water quickly to avoid stagnation in the absence of chlorine;
- regularly change the filter on your device;
- observe the instructions for use.
Our association now invites you to inform yourself as much as possible of the risks involved and the strict conditions to be observed for the use of your reverse osmosis unit.

In fact, in most cases, the water to be distributed is pumped from a well, a collection gallery or surface water. To be distributed, it requires more or less heavy and expensive treatments. As for the energy balance of the operation, we accept as an average value one kilowatt-hour of electrical energy expended per cubic meter of water distributed. The energy required to pump a cubic meter of water from a tank is only a fraction of this value. That said, it is quite obvious that a comparative eco-balance is a study that remains to be done.
At one of his conferences, the director of a distributing company affirmed that never had quantities of heavy metals as high in distribution water as those I had measured in city water. Mons, questioning my competence or my scientific honesty. I have, in fact, measured 25 times more zinc in the city water of Mons than in the water of a series of tanks. We can still doubt the results of a researcher, but much less those obtained by a team during a study spread over several years made in an official laboratory of the state. In fact, in the laboratory of the CSTC (Center Scientifique et Technique de la Construction), in Belgium, we measured up to 11.900 µg / l of zinc in tap water at the outlet of the consumer's tap, and up to at 130 µg / l in rainwater tanks. The ratio observed was similar for copper. (Ref .: K. De Cuyper and K. Dinneg, The quality of water from the tap. Tribune de l'eau, n ° 268/2, March-April 1994, pages 35-42)
a) at your home maybe the mains water is rotten (I knew that in Strasbourg but especially in southern Brittany in Guérande, the water was chlorinated almost like a swimming pool !!!) but it is not the case of all regions. Where we live (Ardennes) it is excellent!
b) nothing prevents you from putting the filters on the network water ... which will anyway be "cleaner" than that of your tank ...
We are dependent on the network ok but you are dependent on the seller of filter cartridges and of course the weather ...
If I understood correctly: you have a 30L tank and you are completely cut off from the water network? Can you give us a little photo report? Your site is restrained ... too bad ...
They talk about financing but by no means economic profitability ... in certain regions I doubt that it will be profitable (especially in renovation) ...
