Water has always been a fundamental part of our lives, constantly in search of well-being through it we select the best for our ego.
But for our system what water should we choose?
The answer to this question is quite simple, there are two standards that define the type of system and the quality of water we should supply.
They are respectively UNI 8065 of 06/1989 and the DM of 26 June 2015 known as the 'Minimum Requirements Decree'.
The UNI 8065:1989 standard sets the chemical and physical parameters of water in plumbing systems for civil use a:
Appearance: clear
pH: greater than 7
Iron (as Fe): < 0.5 mg/kg
Copper (as Cu): < 0.1 mg/kg
Hardness: 15°F
Furthermore, depending on the size of the system, they oblige or recommend filtration; but in order to be able to treat, we need to know what we have. Hence the second question:
What do we get from the public waterworks?
All waterworks are obliged according to ISO 22000 quality standards to periodically check, record and publish the 'technical data sheet' of the water they supply. We can easily find this data on the Internet or by calling the local service.
With this data we can choose our treatments so that they have maximum yield and effectiveness.

What should we do to treat water in the best possible way and ensure not only energy savings but also a long life for our products and systems?
In this chapter we move on to a practical example, in the table "Extract Water Quality distributed in the village of Gargallo in the 2nd half of 2018" the type of water supplied by the Gargallo aqueduct appears.
Our reference values are:
Conductivity: Electrical conductivity provides an indirect measure of the concentration of dissolved substances in the water and consequently its salinity.
Hardness: Hardness mainly refers to the content of calcium and magnesium salts.
From the data in the table, we could easily deduce that rather acidic water flows inside our system, which in the medium to long term could lead to corrosion or hardening of the seals of certain system components or our appliances.
If, as a preventive measure, we add a filter, which is always recommended, and a salt dispenser to reduce the risk of corrosion, we can ensure a long and happy life for our systems and appliances.
