TDS Adjustment for Better-Tasting Water
RO systems with a TDS controller blend a small amount of pre-filtered water back with the purified output to retain some natural minerals — get the ratio wrong and water tastes either flat and metallic or too heavy. We calibrate the TDS controller against your actual source water rather than a generic setting, so the output lands in a taste-appropriate range without over- or under-purifying.
Common signs you need tds adjustment
How our tds adjustment process works
Source & output TDS test
We measure both to establish the current bypass ratio.
Controller calibration
The TDS control valve is adjusted to bring output within a healthy, palatable range.
Taste verification
We check the adjusted output against your preference before finishing.
Reading recorded
Final TDS reading is shared so you have a reference point for future checks.
Frequently asked questions
What is a healthy TDS level for drinking water?
Generally 50–150 ppm is considered good for taste and mineral content, though this varies by source water and personal preference. We calibrate toward a range that suits your taste while staying within safe limits.
Can I adjust the TDS controller myself?
The knob is accessible on some models, but getting the ratio right needs an actual TDS reading before and after — without testing, it's easy to over-correct in either direction.
