Water hardness can cause a number of problems in the home: limescale deposits, clogged pipes, less efficient household appliances, dry skin and hair. Understanding water hardness is therefore essential for choosing the right water treatment. Thanks to effective solutions such as our water filtration, purification and softening systems, HydroSolution helps to improve the quality of tap water, while optimizing your daily comfort and protecting your domestic installations.
Knowing the hardness of the water in your home is essential for choosing the right water treatment system.
To find out if you have hard water in your home, a few clues may help:
- You have limescale build-up in your pipes
- You have low pressure in your taps
- You have stains on your clothes and discoloration after washing
- You have soap stains on your glasses and dishes
- You have soap deposits on your shower glass
- You have dry skin and hair after a shower
- You have limescale deposits on your taps throughout the house
In the table below, you’ll find a census of water hardness in some Quebec cities. It’s important to know the water quality of your municipality, and they share their results annually.
Water hardness is measured in milligrams per liter (mg/L) or grains per gallon (gpg).
