TAP WATER AND WELL WATER
To ensure maximum hygiene and durability of the minipool it is essential to pay close attention to the quality of
the water that will be used to ll it. It is important that the water used be drinkable. It is always advisable not to
use well water because it may be very hard, rich in metals like iron and manganese, and have bacterial loads. Tap
water is recommended.
In the case of very hard or ferrous water it is always recommended to install softening and iron removal systems
upstream.
The company cannot be held responsible for issues related to the use of non-drinkable water or lack of installation
of such systems.
The plumber is responsible for choosing the type of components to be used and the verication of compliance
with the purity and potability parameters of the water supply.
WATER HARDNESS
Water hardness (TH) is determined by the total content of calcium and magnesium present in the water, coming
from their soluble salts.
Water classication:
........up to 7ºf = Very soft water
From 7ºf to 14ºf = Soft water
From 14ºf to 22ºf = Slightly hard water
From 22ºf to 32ºf = Fairly hard water
From 32ºf to 54ºf = Hard water
more than 54ºf = Very hard water
(1°f = 10 mg calcium carbonate per litre of water)
WATER ALKALINITY
Alkalinity (CAT) represents the concentration of bicarbonate ions present in the water. It is expressed as mg/L of
calcium carbonate or in French degrees (°F). Ideal values of alkalinity range between 80 mg/L and 125 mg/L (8°F-
12.5°F). Values outside of this range can more easily cause variations of the pH. Instead, alkalinity within the range
noted makes it possible to "buffer" the pH value, resulting in fewer abrupt variations.
WATER PH
What is pH?
The pH is a chemical parameter that gives an idea of the acidity or basicity of the water. It can assume values
between 0 and 14. By denition water is considered neutral if its pH is equal to 7. It is acidic if the pH is lower
than 7 and basic if the pH is greater than 7. Disinfectants have an ideal pH at which they are most effective. In the
case of heated water treated with bromine products it is recommended to keep the pH value in the range from
7.4 to 7.8 using chemical correctors as needed if the pH is higher or lower to bring the the pH value back to the
recommended interval.
