Stains that say a lot about the quality of your water
Have you noticed blue-green stains on your faucets or sinks?
This is not just an aesthetic problem: it is often a sign that your water contains high levels of copper, caused by an acid imbalance.
These acid stains can cause serious damage to your facilities.
In Quebec, where many homes still use copper or brass pipes, this phenomenon is becoming increasingly common.
But rest assured: solutions exist.
What causes blue-green spots?
Stains caused by acid are often the result of overly acidic water, a phenomenon that may seem harmless at first, but which nevertheless has very real consequences. When water flows through copper or brass pipes, its acidity can gradually dissolve the metals present in the piping over time. As a result, this process releases copper residues that are then deposited as blue-green stains on your sinks, faucets, and other surfaces that come into contact with water. At first glance, these marks may appear to be purely aesthetic. However, their presence signals a deeper problem: over time, this internal corrosion can cause micro-holes to form in your pipes, eventually leading to leaks that can be difficult to detect… until it’s too late.
Signs that your water is too acidic
Beyond visible stains, several signs may indicate acidic water:
- A metallic taste in drinking water
- Discoloration of aluminum surfaces
- Premature wear and tear on household appliances
- Rapid deterioration of water heaters and dishwashers
Why does this problem need to be addressed quickly?
Stains caused by acid will not disappear on their own.
Ignoring this problem can lead to:
- Expensive plumbing repairs
- A reduction in the lifespan of your devices
- Lower quality water for consumption
- Health risks, especially for children
In Quebec, where municipal water is treated, its pH is sometimes slightly low.
This is enough to cause corrosion in older homes.
Culligan reverse osmosis: an effective solution
At Culligan Quebec, we recommend installing a reverse osmosis system to combat acid-induced stains.
This system removes impurities, including copper, at a microscopic level.
It is a four-step process:
1. Prefiltration
The water is first filtered to remove large particles, chlorine, and sediment.
2. Reverse osmosis
It then passes through a semi-permeable membrane, which blocks particles smaller than one micron.
3. Drainage of contaminants
Impurities are drained away, far from your drinking water.
4. Final filtration and storage
Before reaching your tap, the water is filtered one last time for optimal taste.
Advantages of a reverse osmosis system
- Removes over 70 contaminants
- 12 times more effective than a filter jug
- Reduction of microplastics, PFAS, lead, and copper
- Connected technology to monitor water quality
- Helps prevent corrosion in your pipes and appliances
The Culligan neutralizing filter
Another equally effective solution is Culligan’s Neutralizing Filter, designed to rebalance the pH of your water as soon as it enters your plumbing system. By neutralizing acidity before the water even reaches your taps, this filter plays an essential preventive role. It is particularly recommended for homes supplied by a well or where the water is naturally very soft—two situations where the risk of corrosion is often higher. With this system, the acidity of the water is corrected at the source, effectively protecting your pipes from premature wear and tear.
