Dirty or Smelly Water at Your Koh Samui Property
Discoloured, cloudy, scaly or smelly water has several possible causes, and each calls for different treatment. Water that looks clear can still have issues, and water that looks bad isn't always unsafe — so the reliable way to know is a laboratory test. Water quality should be tested before selecting filtration.

Possible causes
Iron & manganese
Cause brown or black staining and a metallic taste, and are often invisible until the water meets air.
Sediment & turbidity
Cloudiness from fine particles, sometimes appearing after heavy rain or pump work.
Hardness
Limescale on fixtures and heaters — a mineral rather than a contaminant, but hard on equipment.
Odour
Often sulfur- or bacteria-related; the specific cause determines the treatment.

What should be checked
- A laboratory water analysis — the foundation for any treatment decision.
- When and how the problem appears — constantly, after rain, or only in hot water.
- The existing filtration, if any, and whether it is overdue for service.
- The water source and its history.
These notes are general guidance only. Water systems vary from property to property, and the actual cause requires a site inspection to confirm.

How Deep Well Samui can help
Laboratory water testing
Identifying exactly what is in your water, rather than guessing from appearance.
Filtration designed from the results
Only the treatment stages your water actually needs, based on the analysis.
Fixing existing systems
Filters that were the wrong type, or that are overdue for media and cartridge changes.
Verification
A retest after installation, so results are documented rather than assumed.

What to prepare before we visit
- What you're seeing — colour, cloudiness, staining, smell or taste.
- When it appears — constantly, after rain, or in hot water only.
- Your water source and any existing filtration.
- What the water is used for (drinking, bathing, guests).
Frequently asked questions
Is my water safe to drink?
We can't say from a description — clear water can carry invisible issues, and discoloured water isn't always unsafe. A laboratory test is the only reliable answer, and we verify treated water with a retest.
Will a filter fix it?
The right filter will — but the right filter depends on what the test finds. A finer cartridge won't remove dissolved iron, and softening won't fix bacteria. Treatment is designed from the analysis.
Why does my water look fine but stain everything?
Dissolved iron is invisible in the glass and only oxidises — turning brown — on contact with air, tiles or laundry. A water test confirms it.
The smell comes and goes — why?
Intermittent odour is often biological or related to the water heater. The cause should be identified by testing before any treatment is chosen.
Get your water tested
Before choosing any filtration, get a laboratory analysis. We'll sample, test and design treatment around the results.
