That Rotten Egg Smell in Your Water Is Sulphur. We Remove It Fast.
Hydrogen sulphide gas creates that unmistakable rotten egg odour in water. It's unpleasant, can stain fixtures, and is a sign your water needs treatment — especially common in well water across GTA's rural edges.
Rotten Egg Smell Throughout the Home
GTA homeowners deal with these water issues daily — and every one of them has a proven solution.
Hydrogen sulphide (H₂S) gas dissolves in water and releases when you run taps, shower, or use your dishwasher — filling your home with a sewage-like smell.
Sulphur reacts with copper and silver in your plumbing, leaving dark black tarnish on fixtures and potentially corroding pipes over time.
High sulphur concentrations make water taste and smell foul, making it essentially unusable for drinking. At certain concentrations, it can also irritate eyes and airways.
Sulphur Odour Is Fully Removable — With the Right System
The right treatment depends on your sulphur concentration and water source. PureFlow's free water test identifies the exact level and recommends the most effective, cost-efficient solution.
