Why city-specific water solutions matter
High calcium and magnesium damage appliances and fixtures and dry out skin. Most GTA water is hard.
Common in well water, causing staining and a metallic taste.
Organic matter in some wells and surface water causes a yellow tint and earthy smell.
Private wells may need UV treatment for microbiological safety.
Tailoring your system to local water chemistry gets you the best performance, lifespan and value.

Questions
How hard is Ontario water?
Most regions range from moderately hard to very hard. GTA municipal water typically runs 7 to 8 grains per gallon (about 120–140 mg/L); private wells can be much harder.
Do I need UV for municipal water?
No. Municipal supplies are disinfected. UV is for private wells, which owners are responsible for testing.
How do I know if I have iron or tannins?
Reddish or orange stains usually mean iron; yellow or tea-coloured water usually means tannins. Our free test confirms it.
