RO-CTOP High TDS

The causes to the High TDS are listed in the timeframe that you've owned your RO system. The grey background applies to systems in use for under 3 months and the white background applies to systems in use for more than 3 months

Make sure all lines to the RO system and within the RO head are not obstructed. Low water pressure result in slightly higher tds than good water pressure.

Wrong membrane direction

TDS test

Normally without the membrane, the RO water's ppm is equivalent to the Tap water's ppm.

(Extremely Rare)

Flow rate test

Clogged pre-filters inadvently lowers the water pressure. Thus cause the tds to escalate.

Use TDS meter to measure the TDS
