High dissolved solids (TDS)
TDS is a single number for everything dissolved in your water. When it climbs, taste changes and scale increases.
How you know this is your problem
- A slightly salty or heavy taste
- Fast scaling in the kettle and the steam iron
- A clear taste difference between your home and another in the same area
Why this happens in Qatar
The number varies by neighbourhood and by tank. A dirty or old tank raises it, and so does the age of the building's internal pipework.
What fixes it
Reverse osmosis is the only method that genuinely lowers TDS — which is why it is the drinking-water filter.
