Yellowish water in taps is a relatively common problem and can cause concern. As well as looking unpleasant, it can indicate problems in the plumbing or the supply network. Identifying the correct cause is essential in order to apply the right solution.
In this comprehensive guide, we explain the main causes of yellowish water, whether it is dangerous for your health and what to do to solve the problem. For quick diagnosis and an effective solution, the Lisbon plumber company is the best solution for checking the pipe and eliminating the source of the problem.
Main causes of yellow water
1. old pipes with rust
One of the most common causes. Old iron pipes oxidize over time, releasing rust particles that turn the water yellow.
2. Interventions in the public network
Work or maintenance on the water network can loosen accumulated sediment in the pipes, causing a temporary change in color.
3. Standing water in pipes
If the water is left standing for a long time (for example, after a vacation), it can accumulate residues and become colored when it circulates again.
4. Limestone and sediment deposits
Internal accumulations can release particles into the water, altering its color and transparency.
5. Water heater or storage tank problems
Old equipment can accumulate rust or sediment that ends up in the taps.
Is yellow water dangerous?
It doesn't always represent an immediate danger, but it shouldn't be ignored. It may indicate the presence of metals or impurities. Avoid consumption until the cause has been identified.
For official information on water quality, you can consult the ERSAR.
How to solve the problem
1. Let the water run
If it's a temporary problem, let the water run for a few minutes. If it returns to normal, it may have been caused by intervention in the network.
2. Check whether the problem is general or localized
- If it occurs in all taps → can be from the mains or the main pipe
- If it only occurs in one → it could be a local problem
3. Inspect the water heater
If the yellowish water only appears in hot water, the problem could be with the equipment.
4. Replacing old pipes
If the pipes are old and corroded, replacement is the most effective solution.
5. Install water filters
In some cases, filters help to trap particles and improve water quality.
