Rusty Water: When Pipe Corrosion Affects Water Quality
If the water coming from your taps appears yellowish, has a metallic taste, or contains rust particles, it could be a sign of pipe corrosion. The presence of iron and metal oxides in the water not only affects its quality but can also damage household appliances and heating systems.
In this article, we’ll explain how internal pipe corrosion contaminates water, the risks involved, and the best solutions for filtering and removing iron sediment.
What Does Yellowish Water or a Metallic Taste Mean?
Rusty water is characterized by a yellow, reddish, or brown color along with an unpleasant metallic taste. These signs indicate oxidation inside the pipes, especially in older systems made of iron or galvanized steel.
Common Causes of Rusty Water:
- Internal corrosion of metal pipes, releasing iron particles into the water.
- Low water circulation, allowing rust residues to accumulate.
- High iron levels in the water supply, worsened by degraded plumbing systems.
While rusty water is not necessarily toxic, continuous consumption can degrade water quality and damage appliances connected to the plumbing system.
How Internal Rust Can Contaminate Drinking Water?
Rust forms when metal pipes oxidize due to prolonged exposure to water and oxygen. This process releases metal residues, which remain suspended in the water you consume.
Main Risks of Rust in Water:
✔ Poor drinking water quality – Alters the taste and color of the water.
✔ Damage to appliances – Washing machines, boilers, and water heaters can clog due to sediment buildup.
✔ Stains on clothes and dishes – Dissolved iron can leave permanent stains on fabrics and utensils.
✔ Impact on skin and hair – Water with high iron content can dry out skin and damage hair.
If you notice that your home’s water is consistently yellowish or contains rust particles, it’s important to investigate the source of the problem and seek appropriate solutions.
Impacts of Corrosion on Heating Systems and Appliances
The effects of rust go beyond just water quality. Heating systems such as water heaters, storage tanks, and radiators can suffer severe damage due to sediment buildup inside their components.
How Rust Damages Appliances:
- Reduces heating efficiency, as sediment acts as an insulator.
- Causes blockages in internal pipes, restricting water flow.
- Shortens the lifespan of appliances, accelerating wear on heating elements and valves.
- Increases energy consumption, as the system must work harder to compensate for blockages.
If your water heater or boiler takes longer to heat water or makes unusual noises, it could be a sign of rust and sediment buildup.
Techniques for Filtering and Removing Rust Sediment from Water
Fortunately, there are various solutions to remove iron and other metallic residues from water, improving its quality and preventing damage to plumbing systems.
1. Installation of Sediment Filters
Particle filters are the simplest solution for removing rust residues before they reach your taps.
Advantages:
-
Installed directly at the water supply entry point.
-
Traps visible particles without altering the water’s chemical composition.
2. Iron and Manganese Removal Filters
For water with high levels of dissolved iron, a specialized iron removal filter may be necessary. These systems use resins to capture metals present in the water.
Advantages:
-
Improves drinking water quality.
-
Reduces discoloration and metallic taste issues.
3. Reverse Osmosis Systems
Reverse osmosis is one of the most effective ways to eliminate not only iron but also other impurities from water.
Advantages:
-
Removes heavy metals and unwanted substances.
-
Ideal for household consumption and appliance use.
4. Replacement of Old Pipes
If rusty water is caused by deteriorated pipes, the best solution may be to replace them with corrosion-resistant materials such as PEX, CPVC, or PVC.
Advantages:
-
Permanently eliminates the source of the problem.
-
Prevents future occurrences of discolored and contaminated water.
